PURPOSE An unexplained clinical observation is the development of posterior capsular opacification (PCO), even when the central part of the posterior capsule has been removed. The purpose of this study was to investigate in vitro the mechanisms involved in the closure of the posterior capsulorrhexis in a capsular bag model. METHODS A sham extracapsular cataract extraction was performed in 71 ...

A Modified Iris Suture Technique for In-the-bag Intraocular Lens Dislocation Clinically significant posterior chamber intraocular lens (PCIOL) decentrations or dislocations occur in the aftermath of approximately 2% to 3% of cataract surgeries. Early inor out-of-the-bag intraocular lens (IOL) dislocations arise within 3 months of surgery, primarily as a result of traumatic zonular or capsular r...

Intraocular lenses (IOLs) are implanted during cataract surgery. For optimum results, stable positioning of the IOL in capsular bag is important. Wound-healing events following surgery lead to modification and secondary visual loss due posterior capsule opacification. At present, it unclear how these biological can affect stability within bag. In present study, a human vitro graded culture mode...

We describe a technique to manage late spontaneous intraocular lens (IOL) and capsular tension ring (CTR) dislocation within the intact capsular bag. The subluxated IOL and CTR complex can be positioned in a closed chamber and fixed to the pars plana at both 3 and 9 o'clock quadrants with the presented ab externo direct scleral suturation technique which provides an easy, safe and effective sur...

Secondary visual loss occurs in millions of patients due to a wound-healing response, known as posterior capsule opacification (PCO), following cataract surgery. An intraocular lens (IOL) is implanted into residual lens tissue, known as the capsular bag, following cataract removal. Standard IOLs allow the anterior and posterior capsules to become physically connected. This places pressure on th...

OBJECTIVE To determine the physiologic effectiveness of multi-site, multi-depth sacral lateral branch injections. DESIGN Double-blind, randomized, placebo-controlled study. SETTING Outpatient pain management center. PATIENTS Twenty asymptomatic volunteers. BACKGROUND The dorsal innervation to the sacroiliac joint (SIJ) is from the L5 dorsal ramus and the S1-3 lateral branches. Multi-sit...
