LASIK is a type of eye surgery that is designed to reduce or even eliminate the need for the patient to wear eyeglasses or contact lenses. This type of surgical procedure is performed with a laser. The eye surgeon will reshape the eye's cornea, which can correct vision issues like farsightedness, nearsightedness, and astigmatism. Whether the degree of correction needed is minor or major, LASIK may be an excellent option. If Dr. Alexandrov determines that a patient may be a good candidate for vision correction with LASIK, she will refer the patient to an eye surgeon with whom she works closely for the procedure.
The LASIK surgery is done by incrementally taking small amounts of tissue off the cornea in the eye. This gradual tissue removal allows for precise reshaping of the cornea, which will, in turn, lead to clearer vision.
Patients must be a minimum of 18 years of age before opting for LASIK eye surgery. Patients must also be in good overall health and have no serious risk factors, something that will be determined well in advance of scheduling the procedure. Patients must have a stable eye prescription for 12 months continuously before LASIK. Although some medical conditions may prevent a person from having LASIK surgery, most people who desire this type of vision correction are able to have it.
In some cases, it will, but vision is not always correctable to perfect 20/20. Although the vision may not be precisely perfect after LASIK, it will be dramatically improved enough that most people are able to go about their lives without vision correction. People who have LASIK may not have 20/20 vision, but they will generally not be able to tell the difference between "perfect" and "almost perfect."
Generally, it is a permanent correction. However, patients should be prepared for the fact that eyesight may change as a person ages.
