Lasik surgery is a procedure used to correct your vision, so that you no longer need to wear glasses or contact lenses. Often times, people who have the surgery have no complications, and their vision is near perfect in just a few days after the surgery. In other cases, however, there can be some complications and eye problems. Any surgery carries certain risks. Before you decide to go ahead with the procedure, you should understand the potential risks.
If too little tissue is removed from the eye, it can result in an undercorrection, and your vision will not be as clear as it could be. This happens most often in people who are nearsighted. If the vision is undercorrected, you would need to have an enhancement surgery within a year, so that the rest of the tissue can be removed.
If the laser removes too much tissue, it can result in an overcorrection. This problem is much more difficult to repair than an undercorrection.
Vision Returning to its Pre Surgery State
Over time, your eyes can return to the level of vision that you had before the surgery. This can occur due to hormonal imbalances, pregnancy, and the abnormal healing of wounds. If this happens, you may need to repeat the surgery.
Visual Loss or Changes
While the risk is very rare, you can experience loss of vision due to complications. You may also not be able to see quite as sharply as you did before the surgery.
If the tissue was not removed in equal amounts on both sides, it can lead to an astigmatism. If this happens, you may need to wear glasses or contact lenses, or you may need to have another surgery.
Double Vision, Glare, and Halos
Following your surgery, you may begin having trouble seeing at night. You may see glare when driving at night. Also, you may notice halos around bright lights, as well as double vision. It is also possible to have difficult driving in foggy conditions or at dusk.
For at least 6 months after the surgery, your eyes may not produce tears the way that they should be, leading to dry eye. This condition can make your vision worse. When this happens, the doctor will recommend that you use eye drops. If the problem is severe, the doctor will place plugs in your eyes, which will keep the tears from draining to the surface of the eye.
When the flap on the front of your eye is folded back or removed during surgery, it can lead to complications, such as inflammation, infections, and excess tears. Also, the epithelium can grow abnormally under the flap when you are recovering from the surgery.
There are several medical conditions, which would make the outcome of your surgery less predictable. Often times, if you have one of the following conditions, you may not be a good candidate for Lasik surgery.
Immunodeficiency conditions caused by HIV or immunosuppressive medications. Unstable medical conditions caused by hormonal changes, pregnancy, and breastfeeding
Eye diseases, such as herpes simplex on the eye area, glaucoma, keratitis, cataracts, and lid disorders. These eye diseases can hinder the surgery results.
While the results of Lasik surgery is often excellent, it is important that you understand the risks involved with this type of surgery, and the eye problems that it can cause.
