Having LASIK or PRK in the past does not prevent you from having cataract surgery. It does, however, make preoperative measurements and intraocular lens calculations more complex.
Why Does Prior LASIK Matter?
LASIK and PRK change the shape of the cornea. Standard IOL calculation formulas were originally developed for eyes that had not undergone corneal refractive surgery, so additional methods and measurements may be used when planning cataract surgery after LASIK or PRK.
What Testing May Be Helpful?
- Corneal topography or tomography
- Detailed keratometry
- Optical biometry
- Review of previous refractive surgery records when available
- Macular or other retinal testing when clinically indicated
Can I Still Get a Premium IOL?
Some patients with previous LASIK or PRK may be candidates for monofocal, enhanced monofocal, EDOF, multifocal, or toric lens strategies. Suitability depends on corneal health, ocular surface status, retinal health, visual goals, and the accuracy and reliability of the available measurements.
What Should You Tell Your Cataract Surgeon?
Tell your surgeon what type of refractive surgery you had and, if possible, provide old records showing your pre-LASIK prescription, operative information, or historical measurements. These records may be helpful for surgical planning.
Set Realistic Expectations
Prior LASIK or PRK can increase the uncertainty of the final refractive result. Your surgeon should discuss the expected range of outcomes and whether glasses, enhancement procedures, or other treatments could still be needed.
