Single loop fixation of posterior chamber intraocular lens in the presence of partial capsular support is usually performed by creation of additional scleral flap or tunnel. This extra port may expose the suture holding the intraocular lens or the tucked-in lens haptics to the outside environment thereby increasing the risk of endophthalmitis. We describe a technique of single loop fixation whe...

BACKGROUND Development of the eye depends partly on the periocular mesenchyme derived from the neural crest (NC), but the fate of NC cells in mammalian eye development and the signals coordinating the formation of ocular structures are poorly understood. RESULTS Here we reveal distinct NC contributions to both anterior and posterior mesenchymal eye structures and show that TGFbeta signaling i...

OBJECTIVE To investigate the prevalence of "masked" pseudoexfoliation (PEX) syndrome in eyes with circular posterior synechiae receiving antiglaucomatous therapy with miotics. DESIGN Cross-sectional prospective study. METHODS Twenty-eight eyes of 27 consecutive patients with circular posterior synechiae and a history of miotic drug use without previous intraocular surgery, inflammation, or ...

This is a prospective clinical assay that included six patients who were diagnosed with penetrating corneal injury, traumatic cataract, and posterior segment intraocular foreign body (IOFB). Following anterior segment repair and extraction of traumatic cataract by clear cornea phacoemulsification, a standard 25-gauge transconjunctival pars plana vitrectomy was performed to find and release the ...

T he history of IOLs began in 1949 with Sir Harold Ridley’s insertion of an artificial lens into the posterior chamber. Although placing an IOL within the space from which the cataract had been removed seemed (and seems still) a natural, almost obvious choice, ophthalmologists abandoned posterior chamber lens implantation within a few years. I reawakened surgeons’ interest in posterior chamber ...

BACKGROUND Non Phaco suture less cataract extraction through temporal approach retains most of the advantages of phacoemulsification but can be delivered at lower cost with better visual out come. METHODS Extra capsular cataract extraction followed by posterior chamber intraocular lens implantation was performed, on 300 eyes of 250 patients. The technique involved was posterior limbal corneal...

Purpose: To evaluate intraocular pressure (IOP) and anterior chamber depth (ACD) change after phacoemulsification with posterior chamber intraocular lens implantation Methods: In this quasi-experimental study, 84 patients with senile cataract were included. All patients had normal IOP. Patients with traumatic and complicated cataract, any history of uveitis, glaucoma, or other ocular disease or...

OBJECTIVE To compare the Po(2) distribution in different regions in the eyes of patients undergoing intraocular surgery. METHODS Before initiation of intraocular cataract and/or glaucoma surgery, an optical oxygen sensor was introduced into the anterior chamber via a peripheral corneal paracentesis. The tip of the flexible fiberoptic probe was positioned by the surgeon for 3 measurements in a...
