Candidate assessment Suitability depends on stable prescription, corneal thickness and shape, eye health, tear quality, age, pregnancy status and realistic expectations.
Procedure and recovery A thin corneal flap is created and the underlying cornea is reshaped. Vision often improves quickly, but dryness, glare and fluctuating vision are common early.
Risks and limitations Risks include persistent dry eye, halos, undercorrection, overcorrection, infection, flap problems and rare loss of best-corrected vision. Reading glasses may still be needed with age.
Alternatives PRK, implantable lenses or continued glasses and contact lenses may be more suitable for some patients.

Is the result permanent?
Corneal reshaping is lasting, but eyes can change with age.
Can dry eye worsen?
Yes, especially in the early months.
Will reading glasses still be needed?
