Brief Summary
This study evaluates the Rayner T-flex Toric IOLs for spherical and astigmatic correction, and rotational stability in cataract surgery. 50 patients with cataract and corneal astigmatism \>= 2 diopters will undergo cataract surgery, with implantation of Rayner toric intraocular lens. Post-operative examination will include IOL axis measurements and refraction.
