Eye Laser Treatment - Repair Damaged Vision

Eye Laser Treatment - Repair Damaged Vision
By
Claire Zamenka

Eye laser treatment goes by several different names. It is known as LASIK (laser-assisted in situ keratomiluesis), LTK (laser-thermokeratoplasty), keratectomy or PRK (photorefractive keratotomy). Using these procedures, a physician can correct a number of vision defects.

Astigmatism is a defect that causes vision to be significantly blurred because of decreased visual acuity. This is very difficult to correct using the traditional lenses found in glasses or contacts, but it can be corrected by eye laser treatment. A procedure such as LASIK can help smooth the cornea, creating a spherical shape, which improves vision.

With myopia, or nearsightedness, the cornea is too steep. This condition can cause eyestrain and headaches because the person is often squinting to see objects in the distance. Eye laser treatment can help correct this refractive error by flattening the cornea. On the other hand, hyperopia, or farsightedness, means that a person can clearly see objects at a distance, but will oftentimes have trouble deciphering letters in a book they are reading. Surgical procedures using lasers can alter the shape of the cornea, thereby increasing the person's ability to see objects that are close up such as books and magazines.

Glaucoma is a loss of vision from optic nerve damage. Intraocular pressure is thought to play a part in this damage. Eye laser treatment can help by creating scars in the eye's drainage system, which can reduce pressure.

Diabetic retinopathy can lead to PDR (proliferative diabetic retinopathy) which can cause loss of vision, neovascular glaucoma and retinal detachment. PDR occurs in patients with diabetes. This can be treated with a form of surgery called PRP (pan retinal photocoagulation).

These procedures are done while the patient is awake. The patient is given some medication to help calm and relax them. Drops are placed to help numb the area. The patient then lies back in a chair and a lid speculum is placed to hold the eyelid open. During the procedure, the patient may experience slight pressure and discomfort, but it should not be painful. The exact procedure the physician uses will depend on the type and degree of vision defect being treated. When this is finished, there will be a shield placed over the eyelid to prevent injury.

After eye laser treatment, there may be some itching, burning or irritation. The eyes may water up, but it is very important not you rub them. There may also be some light sensitivity and the eyes may appear bloodshot. A patient may not wear eye makeup for at least two weeks. No contact sports should be performed for at least four weeks, and during this time, an eye-shield should also be worn at night. It will be 8 weeks before the patient is allowed to swim or use a hot tub. If any severe pain is felt, the patient's physician should be immediately contacted. Post-op visits will be done 1-2 days after the procedure and then regularly until the patient is released from care.

Laser Eye Treatment - Lasik Vs Lasek

Laser Eye Treatment - Lasik Vs Lasek

If you are considering having laser eye treatment then it's important that you understand the differences between the 2 most popular procedures which are Lasik and Lasek. In some instances your laser eye surgeon may insist that you are only suitable for either Lasik or Lasek based on the findings of the tests carried out during your laser eye surgery consultation. In this situation, you have no option but to go with the procedure that is advised by your surgeon. However, if you are suitable for both types of laser eye treatment, then it is important to understand the key differences between the 2 techniques so you can make an informed decision.

Lasik and Lasek are both types of laser eye treatment and involve reshaping the surface of your eye (cornea) to eliminate the prescription in your glasses or contact lenses. The reason you need glasses in the first place is because the light entering your eye is not focussed precisely onto the retina, which is what is required for perfect vision. If you are long sighted, the light entering your eyes falls behind your retina, whereas if you are short sighted the light entering your eye falls in front of your retina. Both Lasek and Lasik reshape the surface of the eye to ensure that the light is refocused permanently onto the retina.

The key difference between the 2 techniques is the way in which the surgeon accesses the part of your cornea which is to be lasered. During the Lasik procedure, your surgeon creates a flap (thin layer of cornea) using a micro-keratome (surgical blade) thus enabling the surgeon access to the inner layers of your cornea that need to be lasered during the Lasik surgery.

There is however no flap created during the Lasek procedure. Instead, the epithelium (outer corneal layer) is loosened with alcohol and then gently moved to the side. This enables the surgeon access to the inner layers of your cornea that are to be lasered during the Lasek eye surgery. This layer is then replaced back over the eye and smoothed over.

The vast majority of people choose to have Lasik (7x more popular than Lasek) and this is primarily due to the fact that the recovery period following surgery is much quicker when compared with Lasek. Most people can return to work and normal activities the day following Lasik surgery, whereas with Lasek it can be up to 1 week. There is also more discomfort involved with the Lasek procedure which is another reason people usually choose Lasik. People involved in extremely physical jobs or who play contact sports are usually advised to have Lasek. The reason for this is that your cornea is slightly weakened during Lasik as a result of the creation of the flap. There is no flap created during Lasik meaning there is no weakening of the eye.

In summary, Lasik eye surgery is the most common procedure, mainly due to the quick and painless recovery procedure. Lasek may be advisable in certain situations but this will be discussed with you by your laser eye surgeon.

Medical Procedures That Can Improve Your Quality of Life

Medical Procedures That Can Improve Your Quality of Life
By
Connor R Sullivan

It used to be surgical procedures were something that was a last resort. It was used in response to a medical emergency and not something a person would look forward to undergoing. Over the last few decades, surgical procedures have been developed that are meant as a way to help people avoid more serious medical problems in the future, or to help them lead a better life right away. These elective surgeries are options for people who have something wrong with them that may not be life-threatening at the moment, but if they were to be able to correct the problem, it could lead to a much better life. For instance, if you have problems with your vision, there are surgical procedures that can correct the problem. The cost of Lasik eye surgery is reasonable so it is an option for many who have vision problems. The cost of Lasik is not always covered by insurance, but your Lasik eye cost may be worth the investment if you never need to wear glasses or worry about contact lenses ever again.

If vision problems do no affect you, there may be another health problem that causes you strife. Those who are severely overweight may want to speak with their doctors about gastric bypass. This surgical procedure allows you to make the size of your stomach smaller, helping food pass through your system. It also forces you to eat less so you are not consuming as many calories as before. There are numerous options now for this procedure, and the risks associated with the procedure is much less than it used to be. This procedure can not only help you lose weight for cosmetic reasons, it helps you lead a healthier life. Those who spend years of their lives overweight end up facing a number of health risks in the future. They are more susceptible to problems like diabetes, cancer, and heart problems. Electing to have the gastric bypass can make a big difference in the health of your future.

Even if your health issues are not as serious as vision or weight problems, there may still be a surgical procedure that can improve your life. Minor procedures include hair implants and mole removal. In some cases, mole removal may be a health problem due to skin cancer, but other times you just want to remove something you are tired of looking at. Hair implants are a minor procedure, but they can make a big difference about how you feel about your appearance. Both of these procedures are done in an outpatient manner, so you stop by for a doctor's appointment, they help you with the procedure, and then you are on our way. Cosmetic procedures like these are paid for out of pocket, but they are often very affordable. In the long run, you may find the investment was well worth it because you will be feeling happy, healthy, and attractive once you have spent some time improving your current situation.

Am I Suitable For Lasik Eye Surgery?

Am I Suitable For Lasik Eye Surgery?
By
Stephen McBride

Lasik sight correction routine is fast attaining popularity and many people around the globe are considering it. Lasik (laser-assisted in situ keratomileusis) is a sort of refractive laser eye operation carried out by eye doctors for the correction of generally shortsightedness. People need to recognise the advantages, risks, and how the Lasik process operates. One of the important matters to turn over is what are the prerequisites somebody needs to fulfill in order to undergo a productive Lasik operation. Although all individual cases should be talked about with a qualified Lasik surgeon, here are a few guidelines to determine if wyouare a good prospect for Lasik.

First of all, the eye ought to be in good order. This signifies that it is not advisable for anybody under the age of 18. This is due to that the shape of the eyeball will keep changing for a few years. If the eye shape alters following the Lasik procedure, the clearness of sight will be impacted. Therefore some Lasik docs advocate holding back until aged 25.

In addition to an age cutoff, the sight prescription for the Lasik prospect ought to be static for at least a year, and preferably for much longer than that. This is for precisely the aforementioned grounds as above. The Lasik routine will only remain effective if the eyeball shape continues unvarying following surgery.

You might wish to note that a lot of older people have received Lasik routine. The principal condition in these types is capable tear production for successful recovery and lubrication post Lasik sight correction.

The Lasik Patient's Eyes need to be in good condition.

This ensures that someone receiving a Lasik operation ought to have had no eye infection nor trauma for at least a year, and needs to have zero scarring on the cornea of the eyeball. Additional things to note is that the person must not have any continual eye trouble, such as an account of viral infection in the eyes.

The medical record of a potential Lasik patient likewise plays an important role. Some long standing conditions, such as autoimmune disorders couls cause some people to be inappropriate prospects for Lasik routine. Consequently we need to be be very definite about our medical circumstances, past and present. Additionally, women who are pregnant or nursing ought to postpone a Lasik operation until afterwards

It is Important That You Read This Before You Have LASIK Surgery

It is Important That You Read This Before You Have LASIK Surgery

Many people are interested in getting LASIK surgery, and they want to know the risks and benefits as well as how the procedure works. One of the first questions you need to ask yourself before getting LASIK vision correction is, "Am I a good candidate for LASIK Surgery?" You need to consult with a qualified LASIK physician and after a preliminary exam you will have your answer. Each individual case is different but here are some basic guidelines to follow before you consider getting LASIK surgery.

Eyes must be properly matured before you can get LASIK. Anyone under 18 years of age should wait to have LASIK as the shape of their eye is still changing and will probably not stop until they are at least 25 years old. If you do it too young your eyes could keep changing shape and the clarity of your vision will be affected. Your vision prescription should be stable for a year or longer as this shows your eyes will not greatly change making the surgery highly effective.

There is no maximum age cutoff as older patients have had the same successes as younger patients. The only consideration in older patients is tear production for successful healing and eye lubrication after the surgery.

Your eyes must be healthy. This means that all LASIK candidates must not have had any eye infections or injury to the eyes for at least a year. Plus you must not have any recurring eye problems.

Your medical history plays an important in becoming a candidate for eye surgery. Some disorders like Lupus will prevent some people from having eye surgery. You must disclose any medical conditions current and in the past to your doctor before you have the surgery. Also pregnant or nursing women should wait before they schedule their LASIK surgery.

Patients with dry eye syndrome are usually not good candidates for LASIK surgery. You must have sufficient tear production for lubricating the eye naturally although minor problems may be aided with medication during the healing process. But those with eyes that dilate very widely are not good candidates for LASIK surgery.

These are some basic guidelines to follow when deciding on having LASIK Surgery.. If you can't meet some of these guidelines there are other eye improvement methods you can look at. If you are generally healthy and have a standard vision problem, you are probably a good candidate for LASIK Surgery. Make sure you find a professional physician well trained in LASIK Surgery to discuss your individual needs in detail.

All You Need to Know About Astigmatism

All You Need to Know About Astigmatism
By
Guzel De Jong

When what your eyes see looks a little distorted and blurry, then you might be suffering from astigmatism. Now, don't panic. Many people have astigmatism, even if they don't know it, and minor cases don't affect the vision in a noticeable way. But what if it does?
Let's see what astigmatism is. It is a condition of the eyes where the cornea is irregular in shape. This causes the light to be refracted differently which results in blurry vision. This difference in curvature may be very slight or more pronounced.


Astigmatism may be so mild you don't even know you have it, or it can cause serious problems such as distorted vision and headaches. Many people with this problem also have myopia or hyperopia.

If you get a regular eye exam, your eye doctor will let you know if you develop astigmatism. Normally, your doctor will measure how your eyes focus light and measure the curvature of your cornea. He uses tests and instruments to determine the curvature of your cornea.

If needed, then this optical defect is treated with corrective actions. It could mean you have to start wearing prescription eyewear, such as glasses or contact lenses, but there are also options such as orthokeratology, laser or other refractive surgery techniques.

Most people will choose eyeglasses. It's safer and not as risky as an operation. The prescription is ground in a special way to compensate for the astigmatism. For the people around you they will look like ordinary glasses.

Contact lenses also work very well for some people. Special toric soft lenses are usually prescribed for astigmatic eyes. They help reshape the cornea for better vision.

Orthokeratology involves fitting a series of rigid contact lenses for a patient to help reshape the cornea. Each set of lenses is worn for a limited period of time, such as overnight, and then removed from the eyes. This helps some people to be able to see without corrective lenses during the day. Note that this is not a permanent cure!

Now to surgery. Laser procedures such as LASIK may also be used to reshape the cornea. This procedure removes an inner layer of the eye tissue to help shape the cornea correctly. Most patients immediately notice improvement in their vision following laser surgery. However, your vision can continue to improve for up to six months afterwards. Though hundreds of thousands of people today have had this type of eye surgery with exceptional results, you should not forget that LASIK is an operation with a certain risk.

How Do Eyes Heal After LASIK Surgery?

How Do Eyes Heal After LASIK Surgery?

Luna Moonfang

Suppose, with eyeglasses what will happen if you are dating with the one you admire most? It is not hard to imagine that your dating will be affected by your glasses. Then, why not consider over LASIK surgery that can help you get rid of glasses and regain perfect vision?

If you want to receive such surgery, you should be cautious about several points. To be simple, you should stick to what your eye doctors have suggested. For example, you will feel some discomfort in your eyes after the wearing off numbing medication. However, if you can realize this and do not rub your eyes, your recovery will be quick and safe with less pain.

Such discomfort will disappear quickly. Some special medications will be used, as antibiotics and anti-inflammatory, to reduce the risk of infection and swelling. Of course, after the surgery, your eyes will be very dry, and the eye doctors will give you some drops to maintain moisture.

After the surgery, you are stepping into the healing period, no less than two months. During this period, you should be very careful, such as do no swim; do not rub your eyes, etc. And even at night, an eye patch is still needed for at least one month.

As mentioned above, rubbing is prohibited. This act can affect the healing process. Anyway, you are not suggested to have strenuous sports within two months.

Generally, eyes are unstable after the surgery. Therefore, you should be careful within one to two months before your eyes are stabilized. The reason is there are some common symptoms within this period, such as glare, haloes, etc.

After the healing process, almost all existing symptoms will disappear once your eyes are stabilized.

If we have some eye problems, we can choose to receive eye surgery. However, in the surgery, no scalpel will be used, but laser. The Excimer laser plays the same role as scalpel in the surgery. Laser surgery is also suitable for those who can not receive scalpel surgery.

Generally, eyeglasses and contact lenses are the commonest solutions for nearsightedness and farsightedness. Of course, laser surgery is also suitable and effective for the two problems. But for sufferers of other complicated eye problems, like astigmatism, those glasses and lenses are not so ideal. On the contrary, LASIK surgery is the best alternative.

In laser surgery, every detail is operated in an accurate way. Safety is also another very important feature of this surgery. The recovery time is very short and receivers can enjoy perfect vision after the surgery. In the surgery, the inner cornea will be reshaped by the laser.
Generally, cutting cornea with laser will lead to great risk. And luckily, this has been much improved in the accuracy of the surgery now.


In U.S., there are no less than one million receivers of laser surgery with very high success rate, almost 80%.

In the past, the surgery on the cornea requires greatly on the surgeons and almost no people can receive it. And now, the emergence of laser surgery has solved all such problems.
Some merits of laser eye surgery have attracted many people to receive it, like the great success rate, short recovery time, etc. Several days after the surgery, receivers can have very good vision. However, this surgery is very expensive. If you earn a lot of money, you can consider of receiving it.


One of the most important steps in the surgery is to find the just right surgeon. It is true that there are more and more surgeons for LASIK. Therefore, it is essential to confirm the identification of the surgeon, including the equipments for the surgery. Also, it is a very good idea to listen to other's feedbacks on the surgeon.

Is LASIK Right For You?

Is LASIK Right For You?
By
Sara Roberts

There are 24.6 million LASIK surgeries performed worldwide and an estimated number of over one million LASIK procedures performed annually in the USA alone. With the prevalence and increasing popularity of LASIK to improve and correct vision, and with a high satisfaction rate for those who underwent the procedure, you may find yourself asking - am I a good candidate for it?
Good candidates for the LASIK procedure are people who are over 18 years of age and have stable prescription glasses or contact lenses for two years. Surgeons want to find out if you have stable vision since people aged 18 and younger have visions that are still developing. Another criteria would be having vision problems such as near-sightedness (myopia), far-sightedness (hyperopia), astigmatism or any combination of these with low or moderated degrees of refractive error. People who want to be free from using contact lenses and glasses, and have realistic expectations of surgery results are also good candidates.
Patients with diabetes, rheumatoid arthritis, Sjogren's disease, HIV, AIDS, lupus, or other chronic diseases are not good candidates. The same is true for people taking certain medications such as steroids, retinoic acid since they may also impair wound healing and affect the outcome of the surgery.
This procedure is not for women who are pregnant or breast-feeding. Pregnant women have fluctuating hormones which causes increased retention of body fluids that may change the shape of your cornea and temporarily change your vision. After surgery, patients are often required to take antibiotics and other medications to promote healing and prevent infections. These medications when ingested by women who are either pregnant or breastfeeding may harm or pose risks to their babies.
Another criteria worth mentioning is to find out if you have sufficient corneal thickness and pupil size. The surgeon would need to cut out a flap of your cornea to sculpt it so having sufficient thickness is important since operating on thin corneas may cause blindness complications. Pupil size is also important in order to help the surgeon plan the corrective procedure better and also to take into consideration your night vision after LASIK surgery. Patients with dry eyes should not undergo this procedure since LASIK may worsen your condition.
Not everyone is eligible to undergo LASIK. Patients should consult their doctors first for potential risks and complications before undergoing any procedure. It also wise to learn more about the procedure itself, the outcomes, short term and long term complications, risks and benefits of this procedure. Lastly, get a list of reputable surgeons who have competency and adequate experience of performing this procedure.

All About Wavefront Technology

All About Wavefront Technology
By
Sara Roberts

In the past an eye examination involved sitting in an examination chair and looking through a device that would scare most children, then declaring "better" or "worse" until the Optometrist was satisfied. This method is acceptable in most circumstances, but due to the subjective nature of the exam, the prescription can be inaccurate. This type of exam isn't able to detect other conditions that may exist either.
Advances in the field of eye surgery has brought a new method of examination to the table though, Wavefront. With Wavefront all the "better" and "worse" is taken out, and this technology can diagnose a wider range of conditions. The best part of this is that now this technology can be applied to eyeglasses as well as eye surgery.
In a popular type of wavefront exam a light is reflected off of the back of your eye (the retina) and a map is made from the way that the light travels in your eye. This exam is simple, requires no subjective input, and is almost instantaneous. More accuracy is assured with this method, and more conditions can be corrected from this map.
As pointed out before, this technology can be applied to eyeglass lenses, here's how. In optical laser surgery, such as Lasik, a wavefront map is used to guide and optimize the laser that creates a custom eye surface (cornea) to achieve the best focus possible. Now manufacturers are using this same precision to correct common issues like nearsightedness, farsightedness, and astigmatism along with the higher-order conditions.
Wavefront type lenses are advertised to be the way to achieve a crisper, clearer view as compared to the conventional type lenses, but will probably not be covered by an insurance policy. The cost of these lenses is generally 25%- 35% more expensive than the conventional lenses, depending on the lenses you select.
With the added benefits of wavefront mapping, lens companies have started using digital correction on both sides of the lenses. This type of correction allows for a finer precision in manufacture process resulting in a lens more suited to the wearer. Additional benefits of wavefront technologies are being developed. The DOD granted $3.5 million dollars to PixelOptics Inc. for the development of an adaptive lens system that is referred to as SuperVision lenses.
In light of these advances, many companies have started to delve into this technology and are now producing wavefront inspired lenses. One company, iZon, produces highly regarded and specialized lenses requiring a specialized machine that creates an optical fingerprint for each eye.

Factors Determining LASIK Surgery Cost

Factors Determining LASIK Surgery Cost
By
Pinky Savika


LASIK (Laser Assisted in Situ Keratomileusis) is the "the newest and most successful surgery that utilizes a laser to reshape the cornea and improve vision". Currently, LASIK eye surgery is a preferred option mainly because of the lesser timed consumed, technological advancement, and performance ratio.
Evidently, the LASIK surgery cost has to be a little high but one should not base everything on costs! Here are given some factors that determine the costs.
- Prices vary in relation to geographical location such as a surgery in metropolitan city will cost more than the suburbs!
- The overall cost also depends on the complexity of the case, the surgery, the equipments used, the care given, the experience of the doctor, and the post-operative care. As per rough estimates, the LASIK surgery costs vary between $500 and $2,500 per eye. Ask the LASIK eye surgeon about the factors that contribute towards the surgery cost.
Other reasons may or may not include these considerations: royalty to the manufacturers, medications used before and after surgery, rent of the premises, office location, expense of disposable items, post operation care and doctor appointments until complete recovery, advertising, and employee salaries.
Wondering what the above things got to do with you? It is simple economics- funds are needed to maintain an establishment. So, how would doctors procure maintenance expense? The fees from patients help in funding. Of course, one can always ask for discounts, which depends on the provisions permissible by law. However, never fall for aggressive advertising gimmick. You might end up paying more than you had bargained for!
As with other surgeries, there is no guarantee on the LASIK eye surgery. Some people tend to think that if they pay more money, better the success rate. All depends on the surgeon's skill and experience. Anyhow, better to check the facilities you are paying beforehand than repent later!

3 Potential Lasik Complications

3 Potential Lasik Complications
By Tina Redman

While the majority of people you will speak with will speak highly about Lasik eye surgery, the fact exists that there are several potential side effects. Keep in mind; this isn't to scare you away from Lasik, any medical procedure has inherent risks to it. In order to make you aware of some of these risks, this article is going to describe three potential side effects that you may experience as a result of Lasik.

The first (and most frustrating) side effect is regression. Regression occurs when a patient's post operative vision returns to its original prescription. The only way to resolve this side effect is to undergo eye surgery again.

Next, many laser eye surgery patients will experience dry eyes (this is by far the most common side effect). This condition can either be temporary or permanent. The condition occurs when the eyes are no longer able to produce enough tears to keeps the eyes moist. If you notice this condition, you should immediately contact your eye surgeon. Most likely, he will advise you to use eye drops, but you should still have your surgeon take a look at you to make sure it doesn't become a serious problem.

The last complication that we are going to discuss is the possibility of developing an eye infection. If you notice an infection developing after your eye surgery, you should immediately contact your eye surgeon. If not treated properly and quickly, infection can lead to diminished vision or in some cases, blindness.

While these three side effects sound dreadful, the fact is that with good post operative care, these complications can be resolved or mitigated. If you notice any of them occurring though, you should contact your eye surgeon as soon as possible.

The Basics of Lasik

The Basics of Lasik
By Tina Redman

For many people with vision problems, the answer to their woes is a phenomenal eye surgery called Lasik. Not only does this surgery resolve the majority of refractive eye problems, it also has a very quick recovery time. As such, this article is going to describe the Lasik eye surgery.

As noted above, Lasik is designed to resolve refractive eye problems (such as astigmatism and farsightedness). In order to resolve them, the eye surgeon uses this medical procedure to reshape the patient's cornea. Because the eye is reshaped, it allows the light to be better focused, resulting in improved vision.

Since a question that frequently arises is the cost of this eye surgery, let's answer that question now. While there are numerous variables which will determine the final cost, it will usually cost around $2200 for a person to have Lasik on one eye. Hence, if you need Lasik on both eyes, it will cost you around $4400.

Another thing to realize is that just because you have Lasik, it will not always be successful. Depending on which medical studies you review, the success rate of Lasik is between eighty and ninety five percent.

Lastly, one of the advantages of Lasik is the fact that the recovery time is very quick. While you will able to see after the surgery, you vision will continue to stabilize for the next three to six months.

As you can see, Lasik eye surgery is a great tool in an eye surgeon's toolkit. If you are interested in finding out if you qualify for Lasik, we recommend you contact an eye surgeon today and schedule a consultation. As a recommendation, you should not go to your consultation with the idea that Lasik is the only procedure which will fix your refractive vision problems; you may find out that there is better eye surgery for your condition and situation.

The Evolution of LASIK Treatments

The Evolution of LASIK Treatments
By Ryan Frank

Lasik eye surgery is incredibly popular today, but just a few decades ago it was a revolutionary innovation in the field of ophthalmology. Lasik is actually an acronym that stands for "laser assisted in-situ keratomileusis", and it was made possible first and foremost by the invention of the microkeratome in the 1950s by Spanish ophthalmologist Jose Barraquer. The microkeratome was a surgical instrument with an ultra precise oscillating blade that allowed doctors to cut thin flaps in the patient's cornea in order to alter its shape.

The invention of the first successfully tested laser in 1960 led to further development in laser technology. The Excimer laser was invented in the early 1970s and would be one of the key technologies that made laser eye surgery possible. The excimer ultraviolet laser was special because, unlike other lasers, it allowed for precision cuts without the need to burn through tissue. Rather, the excimer laser delivered enough energy to break molecular bonds in surface tissue, thus causing them to disintegrate into the air in a controlled manner rather than through burning.

The excimer laser's ability to remove extremely thin layers of surface material with almost no heat or damage to remaining material involved made it a perfect tool to use in extremely delicate eye surgery procedures. The microkeratome developed by Barraquer in 1950 was used to access the cornea, whereupon the excimer laser could then perform surgery on the exposed cornea.

This concept of using the microkeratome in combination with the excimer laser was pioneered by Dr. Palliakaris in 1992. The procedure became known as LASIK and it was instantly popular due to the immediate results it provided, as well as the fact that it involved much less pain and discomfort than previous eye surgery procedures.

LASIK Today

Today, the development of ever-faster and more precise lasers has made laser eye surgery a much more complex field than it used to be in the early 1990s. In addition to Lasik and epi-lasik procedures, IntraLase has added a new level of technology to traditional eye surgery. With IntraLase procedures, a laser blade is used instead of the metal microkeratome blade to cut the flap in the cornea. This results in improved precision and less eye irritation and post-surgery complications.
