Details.
Refractive surgery uses a laser to reshape the cornea and help the eye focus light properly on the retina. Options mentioned on the page include ASLA, LASIK and SMILE. Where patient candidacy has been confirmed, refractive surgery can reduce or eliminate the need for corrective lenses. Most procedures are performed under local anaesthetic. Temporary irritation and dryness may occur after the procedure and are usually managed with medications and eye drops.
