To engender best visual result from LASIK

Having an age of 18 years or more
Having constant eyesight or a change in prescription of not more than 0.50 D within at least 1 year
Not being in the pregnancy or lactation period
Not having a large scar on the cornea
Not having any diseases concerning the cornea and other optical maladies which perhaps can affect the treatment such as severe dry eyes, keratoconus, glaucoma, cataract, amblyopia (lazy eye), macular degeneration, etc.
Not having any diseases about the immune system such as SLE, diabetes, and so on.

The vision screening process by an eye doctor and staff takes about two hours following the steps below:

Measurement of intraocular pressure to determine the risk of glaucoma
Measurement of corneal thickness
Analysis of the corneal surface and capturing a minute detailed picture of the individual’s iris
Thorough testing of eyesight and ocular muscles
Dilated retinal examination to rule out any underlying condition which may affect vision outcome after LASIK

Refrain from wearing contact lenses prior to the examination at least two weeks for hard or semi-hard lenses and three days for soft lenses. This way, the cornea can return to its normal shape, allowing an accurate analysis of the corneal topography.

Have someone drive for you as the eye examination involves the use of dilating eye drops. This will affect your near vision and increase sensitivity to light for about 4-6 hours.

Certain medications such as acne drugs like Roaccutane, Acnotin, Isotane should be discontinued for at least one month prior to the eye examination due to its side effects like having dry eyes.

After eye examination, if the patient can do Lasik , it will take about one hour preparation for the procedure and about 30 minutes in the operating room. After the procedure, patient can return straight home and have a follow up the next day with the doctor. Another one week, one month,3months and 1 year follow ups are done to observe stability of eyesight after laser vision correction.
