Is LASIK safe, and what are its main risks?
LASIK can reduce dependence on glasses in suitable candidates, but it is not appropriate for everyone and does not guarantee glasses-free vision. Risks include dry eye, glare and night-vision difficulty; persistent symptoms and more serious complications can occur.
Details
Suitability comes first
The surgeon checks corneal shape and thickness, prescription stability and the eye surface. Keratoconus, thin corneas or significant dry eye may make LASIK unsuitable. Pregnancy and breastfeeding can affect measurements, so discuss timing before making a decision.
Set realistic expectations
Some refractive error may remain, and reading glasses may still be needed with age. Ask about persistent dryness, halos and difficulty driving at night, as well as what happens if the result falls short of your expectations. A promotional success percentage cannot describe your personal risk.
Questions for the surgeon
Ask why LASIK suits your eyes, which alternatives exist, and how follow-up or complications will be managed. A second procedure is not always possible or appropriate. Severe pain or deteriorating vision after surgery requires urgent contact with the treating team rather than waiting for a scheduled visit.
