Laser Eye Surgery — Procedure Guide, Recovery & Risks | MyMedicPlus

Laser eye surgery uses focused laser beams to reshape the cornea and correct refractive errors including myopia, hyperopia, and astigmatism, reducing or eliminating dependence on glasses or contact lenses.

Suitable for adults over 18 with stable refraction for at least 12 months, myopia up to -12D, hyperopia up to +6D, and adequate corneal thickness. Not suitable for progressive keratoconus or severe dry eye.

A flap or surface ablation is created on the cornea. An excimer laser removes precise amounts of corneal tissue to reshape the surface. The flap is replaced (LASIK) or the epithelium regrows (PRK/LASEK).

LASIK patients notice improved vision within 24 hours. PRK recovery takes 3–5 extra days for epithelium healing. Night driving is restricted for 2–4 weeks; vision stabilises fully within 3 months.

Risks include dry eyes (30%), halos and glare at night, under or over-correction, flap complications (LASIK), corneal haze (PRK), and regression requiring enhancement in 5–10% of patients.

Over 95% of patients achieve 20/40 vision or better; approximately 85% achieve 20/20. Patient satisfaction exceeds 95%. Enhancement procedures address residual refractive errors in 5–10% of cases.
