Lasik Vision Surgery.

Refractive surgeries are cosmetic, elective procedures performed to reshape corneal tissue and correct refractive errors so that eyeglasses or contact lenses are no longer needed. Current procedures include radial keratotomy, photorefractive keratectomy (PFK), and Lasik vision surgery.

Among the different refractive surgeries, Lasik vision surgery is considered as one of the most convenient and has shorter recovery time compared to photorefractive keratectomy or PRK. Statistics show that nearly 99% of patients who used to wear eyeglasses can do without them after undergoing Lasik vision surgery and the visual acuity rates more than 99% as well.

Lasik vision surgery combines delicate surgical procedures and laser treatment. A flap is surgically created and lifted to one side. A laser is then applied to the cornea to reshape it. This type of refractive surgery alters the major optical function of the eye and thereby carries certain surgical risks. The patient must fully understand benefits, potential risks and complications, common side effects, and limitations of the procedure.

Lasik vision surgery does not alter the normal aging process of the eye. If the reason for the procedure is occupational vision requirements, the results must satisfy both the patient and the employer. Precise visual outcome cannot be guaranteed with certainty. Typically, patients must be at least 18 years of age.

The corneal structure must be normal and refractive error stable. Patients are required to discontinue using contact lenses for a period before the procedure, preferably 2 to 3 weeks for soft lenses and 4 weeks for hard lenses. Patients with conditions that are likely to adversely affect corneal wound healing, such as corticosteroid use, immunosuppression, are not good candidates for the procedure. Any superficial eye disease must be diagnosed and fully treated before a refractive procedure.
