Cataract surgery is generally suitable after PRK or LASEK, with similar lens‑calculation challenges to post‑LASIK eyes.
Favourable features after surface laser
The absence of a flap can simplify corneal integrity.
- Stable corneal shape and prescription for several years
- Regular topography without signs of ectasia
- Healthy tear film to allow accurate measurements
- Use of post‑refractive formulas to select the intraocular lens
- Expectation that small residual prescriptions are possible but manageable
Points needing extra attention
Past surface treatments can still affect outcomes.
- History of haze, scarring, or high corrections that altered corneal profile
- Potential mismatch between measured and effective corneal power
- Cautious use of multifocal lenses in eyes with reduced contrast
- Discussion of possible need for glasses or enhancement afterwards
- Detailed consent explaining the added uncertainty in lens power choice
