LASIK is used to treat virtually all refractive conditions that cause distance vision to be unclear. This includes a range of nearsightedness, farsightedness and astigmatism. A screening with your doctor is the best way to determine your candidacy.
LASIK cannot restore focusing flexibility for near objects, the normal aging process known as presbyopia. It does not create clear vision in an eye with amblyopia, otherwise known as "lazy eye."
Again, the vast majority of people that experience blurred vision can be treated with the LASIK procedure. In general, to be eligible for LASIK good candidates: are at least 18 years of age, have a stable prescription (the same prescription) for about one year, are in good general health, and have no eye diseases such as cataracts, glaucoma, keratoconus, or certain retinal and optic nerve diseases.
Should be free of certain eye viruses including herpes simplex and herpes zoster.
Should also be free of certain health problems including uncontrolled diabetes, autoimmune or collagen vascular disease, and any medication or condition which renders the patient immunocompromised.
Patients should make their doctor aware of certain eye problems including amblyopia (lazy eye), strabismus (muscle imbalance), severe dry eyes, previous eye surgery or injury, or any recurrent, residual or active eye conditions which may affect healing.
Other conditions that should be related to the doctor include keloid scarring with previous surgical healing, back problems, claustrophobia or other psychological problems, which may affect the surgery or recovery.
Since hormones may affect the stability of your prescription, pregnant or nursing women are not eligible to pursue laser vision correction. Check with your surgeon for specific eligibility once you are done nursing.
