During surgery, a laser is used to cut a flap in the cornea. If you have any corneal conditions, such as thin corneas, keratoconus (cone-shaped corneas) or a history of corneal abrasions, Lasik may not be a safe alternative for you. After the cornea is cut with the laser, there must be a small amount of tissue remaining that has not been altered by the laser. This is necessary for the cornea to retain its rigidity and shape. In the case of a thin cornea, not enough of this tissue will remain to safely perform the surgery.

People with large pupils are usually not candidates for Lasik. If you have large pupils and have Lasik, you may experience double vision, glare, starbursts and halos after surgery. It may be impossible to drive at night due to the glare and halos.

Cataract patients are not candidates for Lasik. Cataracts worsen over time and will need to be removed eventually. When they are removed, vision can usually be improved when the intraocular lens is implanted.

If you have dry eyes, Lasik may not be recommended, as the procedure can worsen the condition. In some cases, the surgery can be performed, but you will need to use artificial tears or prescription medication to help you produce more tears.

Conditions that slow or prevent healing mean that you are not a candidate for Lasik. Autoimmune disorders such as lupus, rheumatoid arthritis or fibromyalgia will prevent you from having surgery. Diabetes and retinal disorders may also mean that you are not a good candidate for Lasik.

Tips & Warnings
Before you have Lasik, read everything you can about the surgery. Don’t just limit yourself to the information that your doctor provides, seek out information on your own. Go to the library, use the internet, talk to other people who’ve had the surgery and ask about their experiences. Ask them if they would recommend their doctor if they were having surgery again.
