Tolerance to surgically induced anisometropia—A systematic review

Acta Ophthalmologica, Volume 104, Issue 1, Page 10-21, February 2026.
Abstract Surgically induced anisometropia is well tolerated by some individuals, while others experience binocular visual complaints. Surgically induced anisometropia is a common treatment for presbyopia and may also intentionally or non‐intentionally be the results after surgery for unilateral cataract with ametropia in the fellow eye.
