LASIK - FAQ

+What is LASIK?

LASIK stands for laser in-situ keratomileusis, a procedure that involves the use of a laser to reshape the cornea of the eye so that refractive capability is improved. This allows the correction of varying degrees of myopia (short-sightedness), hyperopia (far-sightedness) and astigmatism (“san guang”).

+How do I know if I qualify to undergo LASIK surgery?

You would have to be at least 18 years of age to ensure you have achieved a stable refraction status. You should not have any significant illnesses nor be on any medication that could adversely affect the surgery. You would have to be generally healthy with a refractive condition that is not overly severe or outside the accepted treatment limits of LASIK surgery. Importantly, you should have realistic expectations with a good understanding of the risks and benefits of LASIK surgery. Pregnancy is a definite disqualifier. Eligibility is best determined through a pre-LASIK evaluation with your doctor.
