[Combined vitrectomy-lensectomy surgery with bag-in-the-lens or lens in the bag implantation: comparison of final visual acuity].

Introduction: Combined vitrectomy-lensectomy surgery is a safe and effective procedure. Nevertheless, it is frequently complicated by posterior capsule opacification and the formation of posterior synechiae. These complications can be avoided by placing a "bag in the lens" (BIL) implant.

Bag-in-the-lens implantation helps avoid posterior synechiae of the iris after phacovitrectomy.

Purpose: To compare the rate of posterior synechiae of the iris (PSI) occurrence after phacovitrectomy between a group with lens-in-the-bag (LIB) implantation, that is, implantation in the capsular bag, and a group with bag-in-the-lens (BIL) implantation.

Setting: CHU de Caen, Department of Ophthalmology, Caen, France.

Design: Comparative retrospective study.

Optomechanical response of human and monkey lenses in a lens stretcher.

Purpose: To quantify the forces necessary to change the shape and optical power of human and monkey lenses.

Methods: Cynomolgus monkey (n = 48; age: 3.8-11 years), rhesus monkey (n = 35; age: 0.
