OCTOBER 2010 CATARACT & REFRACTIVE SURGERY TODAY 39 A rguably, the single most significant complication faced by today’s phaco surgeon continues to be rupture of the posterior capsule.1 When the posterior capsule is breached, vitreous that presents anterior to the plane of the capsule must be removed. Fortunately, in the setting of small-incision surgery, if the ophthalmologist adheres to certa...

Repair of the posterior capsule is advocated to reduce dislocation after total hip replacement (THR). To date, no predictable physical findings are reported in the literature to assess the capsular integrity and risk of hip dislocation after the posterior approach. The internal rotation test is performed at 4 to 6 weeks postoperatively with the hip and knee flexed at 90° while the patient is su...

PURPOSE To present a cause of posterior capsule aspiration and a technique using optimized parameters to prevent it from happening when operating soft cataracts. PATIENTS AND METHODS A prospective list of posterior capsule aspiration cases was kept over 4,062 consecutive cases operated with the Alcon CENTURION machine and Balanced Tip. Video analysis of one case of posterior capsule aspiratio...

The nervous fibers in the human internal capsule were mapped according to their three-dimensional orientation. Four human cadaver brains were cut into comparable and standardized sections parallel to the ACPC-plane, stained with DiI, and analyzed using a combination of confocal and polarized light microscopy at the same time. This combination provides information about the structure and orienta...

PURPOSE To image the posterior zonular attachment site by using environmental scanning electron microscopy (ESEM). METHODS A custom-made device was designed to mount human cadaveric lenses, with the zonule, ciliary body, and sclera attached, inside an environmental scanning electron microscope (ESEM). The mount was designed to allow radial stretching to enhance exposure of the accommodation a...

PURPOSE To develop and validate a digital imaging and analysis technique for assessing the extent of posterior capsular opacification after cataract surgery. METHODS Retroillumination images of the posterior capsule were obtained by using a digital camera mounted on a slit lamp. The images were analyzed using an available image analysis software program. The image acquisition and analysis tec...

nd:yag laser capsulotomy is accepted as standard treatment for posterior capsule opacification (pco). although, nd:yag laser capsulotomy is a noninvasive and safe treatment it carries risk of some complications. using less total energy and performing smaller capsulotomies are effective choices to decrease complications after nd:yag capsulotomy.

The purpose of this study was to quantify regional variations in material properties of the glenohumeral joint posterior capsule and to compare these data with the anterior band of the inferior glenohumeral ligament (AB-IGHL). Mechanical properties were determined for individual bands of the AB-IGHL, superior posterior capsule (SUP-PC), middle posterior capsule (MID-PC), and inferior posterior ...

BACKGROUND The middle genicular artery (MGA) is responsible for the blood supply to the cruciate ligaments and synovial tissue. Traumatic sports injuries and surgical procedures (open and arthroscopic) can cause vascular damage. Little attention has been devoted to establish safe parameters for the MGA. PURPOSE To investigate the anatomy of the MGA and its relation to the posterior structures...
