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.

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

Reasons to Get Lasik Surgery
Reasons to Get Lasik Surgery
By Connor R Sullivan
Since the early 2000s, the amount of people who choose to have Lasik eye surgery completed has risen dramatically, especially now that there has been plenty of time for the method to be perfected. Davis vision care is, of course, one of the many options for those who elect not to have this kind of surgery performed on their eyes. However, as far as Lasik surgery is concerned, it is currently one of the most sought after elective surgical procedures in the United States. Now, some eyemed VSP will cover at least some, if not all of the costs of the surgery, which makes it even more alluring to potential patients. There are many reasons why one might want to have eye surgery to improve their sight. Below is a list of explanations of the different benefits that can come with having this surgery done:
1. Naturally, your vision will improve dramatically, better than it would with glasses and/or contact lenses. The reason being is that contact and/or glasses prescriptions are not always exact when it comes to your vision. Also, they are meant to help you to see, instead of being your actual eyes. Having Lasik surgery makes it so that your eyes are able to do the work they are meant to do, which means they then do not need any help, such as contacts and/or glasses anymore.
2. Paying a pretty large amount of money for Lasik up front for the surgery will actually save you money in the future. People who have Lasik surgery completed rarely have to wear glasses and they do not need to wear contacts. This will save your money not only on these products, but you will save on your eye care insurance as well. The way you save on your eye care insurance is that there is still a deductable for contacts and/or glasses, so you would not have to worry about this if you have the Lasik procedure.
3. Most people will tell you that when they swim or get into any kind of water with their contacts in, their eyes get sore or dry because the chlorine in pools takes the moisture out of the contacts, so the more they stick to your eyes. If you have a Lasik procedure, this will most likely not be a problem for you any longer. It is important to remember, though, that just because you do not have contacts because of the Lasik surgery, it is does not mean that your eyes will never get dry from pool water ever again, but it will most likely not be as big of an issue as it would be with contacts.
It is very interesting to see that more and more people are deciding to get rid of the contacts and/or glasses in favor of paying more money up front so they can save money in the future because they will be contact and/or glasses free. With the economy the way it is now, it will be interesting to see if this trend continues as it seems that more people are trying to save their money, by cutting back on elective surgical procedures.

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.

Lasik Eye Surgery Guide
Lasik Eye Surgery Guide
By Yan Susanto
Today Lasik is considered as a common eye surgery to correct vision. Performed with the use of laser, lasik helps to easily remove blurry vision, farsightedness, short sightedness, and other vision impairment issues with the eye.
This surgery though safe, can't be considered risk free as all surgical procedures normally involve some amount of risks. As such proper care before and after is necessary.
Keep in mind that there are some people who are not a good candidate for lasik surgery for some reasons or the other.
If you fall in any of the following category it is advised that you refrain from undergoing any eye surgery.
1.Those that have serious myopia or hypermetopia.
2.Those that have thin or cone shaped cornea.
3.Those with with high eye cylinder.
4.Anyone who is prone to eye infections or suffer from dry eyes.
5.Anyone who has cancer or experienced positive in HIV.
6.Those that are addicted to drugs and steroids or use them methodically.
These are but some the reasons why a person is not advised to undergo lasik eye surgery. It's therefore important to consult an eye consultant before you plan to do any eye surgery to avoid any future eye complications.
Familiarize yourself with the risks and complications often associated with the surgery and what to do before and after the surgery. Talk to the doctor about the procedure, the cost, complications, and other such issues before deciding if this kind of eye surgery is suitable for you.
While lasik surgery can't guarantee a 20/20 vision, it is certainly a good option to get rid of glasses or contact lenses and the freedom to see the world without the use of any visual aid.
