LASIK Risks & Side Effects: A Straightforward Patient Guide
Dr. Nikhil Nasta
2 min read
LASIK is one of the most studied elective surgeries in ophthalmology - and it also has real trade-offs. Major institutions (including regulatory and professional bodies) emphasise the same themes: dryness and night-vision symptoms are common early, serious complications are uncommon, and patient selection matters enormously.
This guide is written to help you ask better questions in consultation, not to replace informed consent with your treating surgeon.
Common side effects (many improve with time)
Dry eye and irritation
Temporary tear-film disruption is very common in the first weeks to months. A minority of patients have longer-lasting dryness requiring ongoing therapy.
Glare, halos, starbursts
Especially noticeable at night or in high-contrast lighting early after surgery. Many patients improve substantially, but not everyone returns to “perfect” night optics.
Fluctuating vision
Early healing can make vision feel “sharp one hour, softer the next.” Persistent blur should be evaluated.
Less common but important complications
Examples your surgeon should discuss (incidence varies by technique and case mix):
- Infection (rare but vision-threatening if delayed)
- Inflammation under the flap (e.g., diffuse lamellar keratitis) - usually treatable if caught early
- Epithelial ingrowth or flap-related issues (more relevant with flap-based LASIK)
- Under-correction / over-correction - sometimes addressed with enhancement when safe
- Corneal ectasia risk - why topography and thickness rules exist
“Red flag” symptoms after LASIK
Seek urgent care if you have severe pain, rapid vision loss, a shadow/curtain, or copious discharge.
How to reduce your personal risk
1. Choose comprehensive screening (topography, thickness, dry eye assessment - not a quick refraction-only check).
2. Be honest about contact lens overwear, eye rubbing, autoimmune disease, and pregnancy plans.
3. Follow drop schedules and avoid rubbing your eyes during early healing.
4. Match technology to your eyes, not to advertisements.
