Refractive procedures manipulate the eye to improve vision. Though there are several types of refractive procedures, the most popular is known as LASIK (laser assisted in situ keratomileusis). LASIK involves reshaping the cornea using incisions and lasers. An incision creates a flap which is folded back. Lasers are then used to reshape the middle layer of the cornea and correct the vision. The flap is folded back and allowed to heal, resulting in much clearer vision.
Not everyone should consider a LASIK procedure. Candidates should be over 18 years of age. If you are pregnant, nursing, or suffering from a number of diseases, you probably are not eligible for LASIK. You are also not eligible if your prescription has changed a great deal over the past year. Talk to your eye doctor about LASIK. They will be able to assess your eligibility, the risks you may encounter, and they can recommend how to move forward.
For the most part LASIK is a safe procedure. However, in rare cases, there have been complications that have arisen after the procedure, including droopy eyelids, constant discomfort or the inability to wear contact lenses. In even rarer cases, there have been complications during the procedure. However, as technology improves, there will likely be a decrease in these instances.
