PURPOSE To investigate mechanical properties of the human posterior lens capsule. METHODS Twenty-five human donor eyes were obtained from an eye bank. The age of the donors ranged from 1 to 94 years. Test specimens were prepared as tissue rings from posterior lens capsules by means of excimer laser. Capsular thickness was measured microscopically as the difference in focus between microspheru...

Posterior polar cataracts present special challenges to the cataract surgeon. These are often associated with weakness/dehiscence of the posterior capsule and thus have a higher rate of intraoperative posterior capsule rupture. The surgeon needs to adhere to special surgical strategies to minimize the risk of a posterior capsule rupture. These include, adhering to the principles of closed chamb...

PURPOSE To measure interspecies thickness differences in the central anterior and posterior capsules of postmortem crystalline lenses, by a technique that maintains the anatomic integrity of the lens. METHODS Central capsule thickness was measured with a custom-built, noncontact optical system, using a focus detection technique. Anterior and posterior lens capsule thickness measurements were ...

Objective- To find normal value of thickness of the lens capsules in domesticated rabbits by ultrasonography. Design- experimental in vivo study and clinical trial. Animals- Twelve matured and immature domesticated rabbit. Procedures- The eyes of 12 non anaesthetized domesticated rabbits were sonograophed using a linear 6-12 MHz high frequency transducer. The thickness of anterior and posterior...

Introduction: Equality between the extension gap (EG) and the flexion gap (FG) is one of the most important factors for good clinical results in total knee arthroplasty (TKA). The gap situation during surgery has a wide variation. The EG needs to be widened in patients with varus knees that have a small EG. For this purpose, posterior soft tissue release is necessary to avoid additional resecti...

INTRODUCTION Primary posterior capsular plaques can be highly adherent to the posterior capsule leading to possible posterior capsular rupture during attempted removal. Here we describe a novel method for posterior capsular plaque removal using a technique inspired by the experience of retina surgeon in the peeling of membranes from the posterior pole. METHODS Retinal end-grasping forceps wer...
