Tests and Consultations Before a LASIK Surgery

LASIK eye surgery is known to be highly effective in correcting common vision problems. The procedure uses laser technology to reshape the patient’s cornea underneath a corneal flap; and results in the patient being able to see more clearly without the aid of eyeglasses and other corrective lenses.

While LASIK has a very high rate of success and is considered to be a very safe procedure, it is not for everyone. In some patients, certain pre-conditions can affect the outcome; while in others, LASIK may simply not be the appropriate treatment. To maximize the chances of success and to determine suitability for the procedure, pre-testing needs to be done on patients. Specifically, some of the information that the eye doctor needs to know are the following:

• The true capacity of one's vision (prescription)
• The presence of infections that could be treated, or may inhibit the procedure
• The quality and quantity of tears produced in both eyes
• The shape of the cornea before the procedure
• The thickness of the cornea
• The sizes and measurements of one's pupil when both exposed and absent to light.

Certain conditions, such as an infection or poor production of tears, can be corrected before the surgery is done. However, other conditions, such as a thin cornea, may altogether disqualify a person from the procedure. Those who wish to know if they are good candidates for LASIK should consult with a reputable eye doctor to find out.
