Scleral fixation of intraocular lenses (IOLs) and adjunctive capsular devices can be performed under the protection of a scleral flap. A modification of this technique uses a scleral pocket initiated through a peripheral clear corneal incision. Full-thickness passage of a double-armed suture through the scleral pocket and conjunctiva, with subsequent retrieval of the suture ends through the ext...

THE closure and healing of the wound in cataract surgery is a most important factor in the success of the operation, and various suturing techniques have been evolved. The present communication attempts to evaluate the results in 668 cases operated on from January to November, 1961. The same pre-operative preparation, operative technique, and post-operative treatment were used, and the same thr...

Purpose. To report a new technique for anterior placement of tubes for glaucoma drainage devices to reduce the risk of tube erosions. Methods. Retrospective review of select cases of Ahmed Valve surgery combined with the novel method of a limbal-based scleral flap covered by a scleral patch graft to cover the tube at the entrance through the limbus. Intraoperative and postoperative illustration...

The prediction of aerodynamic characteristics and smart flap of airfoil under the ground effect are carried out by the integration of computational fluid dynamics. Considering different types of beams, a parametric bending profile of a smart flap is designed. Cantilever beam with uniformly varying load with roller support at the free end is considered in here. A pressure-based implicit procedur...

to compare the success of patients with ocular hypertension, secondary to pars plana vitrectomy and silicon oil tamponade, who had an ex-press glaucoma filtration device p50 (alcon laboratories, inc. fort worth, texas, usa) to those who had conventional trabeculectomy this study has been performed. the records of 10 eyes of 10 consecutive subjects who had ex-press implants and 9 eyes of 9 conse...

The introduction of perforator flaps represented a significant advance in microsurgical reconstruction. However, confusion has developed due to the erroneous belief that perforator flaps are different from conventional flaps. The concept of the perforator is not new, but is an idea that evolved from the conventional flap. In fact, some of the flaps used by microsurgeons were perforator flaps. T...

PURPOSE To compare surgically induced corneal refractive change following trabeculectomy with the nonpenetrating trabecular filtering surgeries with and without implant. SETTING Department of Ophthalmology, Ege University School of Medicine, Izmir, Turkey. METHODS A consecutive series of 34 patients (34 eyes) with uncontrolled open-angle glaucoma had trabecular filtering surgery. Patients w...

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...

Aim—Membrane formation in the chamber angle induced by argon laser trabeculoplasty (ALT) can be a cause of treatment failure. Identification of risk factors for membrane formation was the primary aim of this retrospective study. Methods—Semithin sections of trabeculectomy specimens obtained in a 2 year period were examined by light microscopy. 122 eyes which were treated with one or more ALTs b...
