Effect of a single-piece and a three-piece acrylic sharp-edged IOL on posterior capsule opacification.

Background: To compare the intensity of posterior capsule opacification (PCO) between two intraocular lenses (IOLs) of the same optic material, but with different haptic design (1-piece vs. 3-piece).

Methods: This prospective intraindividual controlled cohort study comprised eighty eyes of 40 patients with bilateral age-related cataract.

Influence of blue-light-filtering intraocular lenses on color perception and contrast acuity.

Purpose: To compare contrast acuity at different illumination levels and color vision and the subjective impression in patients after bilateral cataract surgery with a mixed implantation of a blue-light-filtering and an ultraviolet (UV)-filtering intraocular lens (IOL).

Design: Randomized, controlled, double-masked, and bilateral study with intraindividual comparison.

Participants: This study included 48 eyes of 24 consecutive patients with age-related cataract.
