For some people, LASIK may offer a viable option, however, it is always a good idea to know both the risks and the benefits before deciding. Not all people are good candidates for this type of eye surgery. For some people the risks are much higher than the benefits.
LASIK surgery should be performed by either a medical doctor who has received training in eye surgery using a laser, or an ophthalmologist.
LASIK surgery is most often used to correct hyperopia, myopia, and astigmatism. These are the eye conditions most likely to result in wearing glasses. They are also conditions that have been successfully treated using a less invasive treatment than surgery.
Before jumping into the surgery, there are a few things that you should discuss with your doctor, which we’ll discuss below. Sadly, you may have to bring up these things with your eye doctor because many LASIK patients have reported that they were not fully informed of the possible problems resulting from the surgery.
What Will Actually Happen During the Surgery?
The doctor will make a cut in your eye so that they can pull back a flap. This flap is pulled back to allow the laser to reach the corneal stoma and make the necessary corrections.
When the surgery is complete the flap is replaced with care to ensure that no dirt or air is trapped beneath it. The eye is then allowed to heal naturally. In most cases no sedative is used for this procedure.
The benefits of the surgery are said to include never having to wear glasses again. Only you can decide if that is enough of a benefit to allow someone to cut into your eye. Read the fine print carefully before you agree to surgery. What is considered to be successful treatment doesn’t necessarily mean that you’ll be able to toss out the glasses.
The Most Common Risks of LASIK Eye Surgery
Several studies have been done on the incidence of dry eye after undergoing LASIK surgery. The American Journal of Ophthalmology reported a 36 percent chance of dry eye after the six month healing process was complete.
Another study published by Hovanesian et al. reported up to a 48 percent chance of dry eye developing after the same period. As you can see, it is difficult to set a definitive number, but the fact remains that the chance of developing dry eye after the surgery is real.
If left untreated, dry eye can result in less than optimum results from the surgery. It is important to know that in some cases dry eye cannot be treated or does not respond to treatment and can result in permanent chronic pain or impaired vision.
Diffuse Lamellar Keratitis (DLK), also referred to as “Sands of the Sahara” has also been recorded after LASIK surgery. The nickname comes from the feeling of having sand in your eyes – all the time! DLK results when dead cells lodge under the corneal flap.
The eye treats this like a foreign particle and tries to flush it out. Sadly, this can result in permanent vision loss or scarring of the eye if not treated immediately.
Other Reported Complications Resulting From LASIK Surgery
- Corneal Ectasia (bulging of the cornea)
- Increased sensitivity to light
- Vitamin D deficiency caused by sun sensitivity
- Over- or under-correction
- Fluctuating visual acuity (changes in clarity)
- Seeing double or ghost images
- Seeing halos around lights at night
- Debris under eye flap
- Developing astigmatism
- Small break or hole in the macula
- Posterior vitreous detachment (when the vitreous membrane separates from the retina)
- Thin or buttonhole flap (caused when an incomplete flap is created during surgery)
- Eye floaters
As we said earlier, LASIK may be the right choice for some people. This is a decision that you will have to make for yourself. We are just trying to make sure that you know the risks involved. Most invasive procedures prove to have more complications than non-invasive treatments.
Look at LASIK surgery the same way that you would look at a new drug your doctor wanted you to take. You would want to ask your doctor about all the possible side affects. You’d want to know how often people who have used the drug have experienced problems with it. You would ask about possible dangers associated with the drug and about how it would react with other drugs you were taking.
Before you have LASIK surgery you should really be asking all these questions about the procedure and side affects from it as well. Only you can decide what risks you are willing to take. However, before you can make that decision you have to know what the actual risks involved are. Don’t be afraid to ask. It’s you eyes you’re talking about. You have the right to know what could result from the surgery.
The FDA website on LASIK surgery has some great advice: “Before undergoing a refractive procedure, you should carefully weigh the risks and benefits based on your own personal value system, and try to avoid being influenced by friends that have had the procedure or doctors encouraging you to do so.”
