We treated an opacified membrane on the anterior surfaces of the posterior capsule of two cynomolgus monkeys that had undergone extracapsular cataract extraction and intraocular lens insertion. After development of opacification of the posterior capsule, argon laser energy was employed in an attempt to debride the capsules while maintaining structural integrity of the capsule. With this technique, small areas of destruction of the membrane on the anterior surface of the posterior capsule were created with preservation of the capsule.

Purpose: Severely myopic eyes have been associated with high posterior capsule opacification (PCO) incidence. Although it has been reported that myopic eyes have weaker or more delayed capsule adhesion than emmetropic eyes, it is unclear whether/how dioptric power and posterior curvature of IOLs affect IOLs' affinity for the posterior lens capsule (PLC) and their PCO potential.
Methods: To investigate this, acrylic foldable IOLs with increasing dioptric power of 6.

Background: Mycobacterium bovis BCG is the human tuberculosis vaccine and is the oldest vaccine still in use today with over 4 billion people vaccinated since 1921. The BCG vaccine has also been investigated experimentally in cattle and wildlife by various routes including oral and parenteral. Thus far, oral vaccination studies of cattle have involved liquid BCG or liquid BCG incorporated into a lipid matrix.

Optic capture of a three-piece lens in the absence of posterior capsule support is an effective strategy for stabilizing and sequestering the optic to reduce the risk of dislocation and UGH syndrome compared to sulcus placement. We present a novel technique that facilitates optic capture in the presence of a contracted, fibrotic rhexis opening, while minimizing stress on the zonules by using iris retractors to assist in stabilization and expansion of the rhexis, followed by direct injection of the optic of the lens behind the anterior capsule opening into an optic captured configuration.

Introduction: Bony and ligamentous ankle injuries are some of the most commonly treated injuries by orthopedic surgeons. Open ligamentous ankle injuries without an associated fracture or dislocation are rare and to our knowledge have only sparsely been described in the literature. We present a case and successful treatment of an open lateral ankle injury with capsular rupture and ligamentous damage without fracture or dislocation in a 22-year-old female.
