A very common question after LASIK is whether the procedure affects cataracts — either increasing risk, preventing them, or complicating future cataract surgery.
Does LASIK Increase Cataract Risk?
No — LASIK does not increase your risk of developing cataracts. Cataracts are caused by age-related changes in the protein structure of the natural crystalline lens inside the eye. LASIK only affects the cornea and has no effect on the lens. You will develop cataracts at whatever rate your genetics and lifestyle determine.
Can You Have Cataract Surgery After LASIK?
Yes — and this is increasingly common. However, cataract surgery after LASIK requires special planning. The standard IOL power calculation formulas assume a normal corneal curvature. After LASIK, the cornea has been reshaped, so modified formulas must be used (Barrett True-K, Haigis-L, or Holladay 2). At Centre For Lasik, we maintain detailed records of all patients’ pre-operative measurements for exactly this reason.
Can LASIK Prevent Cataracts?
No — LASIK cannot prevent cataracts. However, for patients in their mid-50s or beyond, Refractive Lens Exchange (RLE) may be preferred over LASIK as it addresses both the refractive error and eliminates future cataract risk simultaneously.
