Dry eye and fluctuating vision
Temporary dryness is common after LASIK and can sometimes persist. Pre-existing dry eye may influence both symptoms and suitability. Vision can fluctuate during healing and may not feel identical every hour of the day.
Report symptoms and attend follow-up rather than assuming every sensation is normal or every symptom is permanent.
Glare, halos and night-vision symptoms
Some people notice starbursts, glare or halos around lights. These symptoms often change over time, but persistent effects are possible. Discuss night driving and visually demanding work before treatment.
No ethical surgeon can promise that you will never experience these symptoms.
Residual correction and enhancement uncertainty
Undercorrection, overcorrection or regression can leave a refractive error. Glasses or contacts may still help certain tasks, and an enhancement may be considered in selected cases after stability and safety are assessed.
Further treatment has its own limitations and is not guaranteed to produce a chosen number on an eye chart.
Infection, inflammation, flap issues and ectasia
Less common but important complications include infection, inflammation, flap-related problems and corneal ectasia—a progressive weakening and bulging of the cornea. Severe outcomes can threaten vision.
Careful screening aims to reduce risk, not eliminate it. Ask how the surgeon’s findings affect your personal risk and what follow-up or urgent care is available.
Making an informed choice
Read the consent information, ask about alternatives and take time. Recognised patient resources from the American Academy of Ophthalmology and US FDA provide additional balanced context. Online education supports—but never replaces—a personal ophthalmic examination.
