Often, both eyes eventually need treatment, although one eye is usually worse. I operate one eye at a time for safety, comfort and the chance to fine‑tune the plan for the second eye.

For the technically minded: Sequential unilateral surgery lowers the already small risk of bilateral endophthalmitis and allows refractive feedback from the first eye to adjust the second eye’s target. Inter‑eye optimisation can improve refractive accuracy by accounting for effective lens position behaviour in the individual.
