PURPOSE A new, potentially accommodative posterior chamber lens (PCIOL) was designed based on principles elaborated by Hanna using finite element computer simulation methods. We report 3-month postoperative results in patients. METHODS In a prospective study, 12 eyes of 12 patients (age 45 to 87 yr) underwent phacoemulsification for cataracts and PCIOL implantation. The PCIOL, 1 CU, has hapti...

The efficacy and safety of a combined operation for cataract and glaucoma is established. This procedure of combined cataract extraction and trabeculectomy is taken one step further by the simultaneous insertion of the Severin intraocular posterior chamber lens implant. The results of treating 24 eyes in terms of control of glaucoma are discussed. Postoperative miotics may be required to improv...

PROBLEM Effective tamponade of a Descemet-stripping endothelial keratoplasty graft with a gas bubble requires that there is no route for the bubble to escape into the posterior chamber. SOLUTION Exchange the angle-supported anterior-chamber intraocular lens (IOL) for an iris-enclaved Artisan IOL and position the IOL haptics over the peripheral iridectomy to occlude it to the extent that no ga...

CASE REPORT We present the clinical case of a 68 year-old woman who developed a pupillary block acute glaucoma due to vitreous hernia into anterior chamber following posterior dislocation of the intraocular lens one month after an Nd:YAG capsulotomy. DISCUSSION We should consider these symptoms in the differential diagnosis of pseudophakic acute glaucoma, especially when visualisation of the ...

Unoperated cataract in the developing world remains ophthalmology's major unsolved problem. Recent developments have brought into question the assumptions of those who have thought that extracapsular surgery with implantation of a posterior chamber intraocular lens is an unrealistic approach to the treatment of global cataract blindness. High-quality 1-piece posterior chamber intraocular lenses...

BACKGROUND This study evaluates patients with congenital aniridia and cataract who underwent phacoemulsification, capsular tension ring placement, and foldable intraocular lens implantation. METHODS In this prospective case series, 10 patients (17 eyes) underwent cataract surgery via a 3.2 mm clear corneal incision. A continuous circular capsulorhexis with <6 mm diameter was employed. A capsu...

AIM To identify risk factors for the development of posterior synechiae of the iris (PSI) after 23-gauge phacovitrectomy. METHODS A retrospective chart review was performed in consecutive Asian patients treated with 23-gauge phacovitrectomy with a 3-piece intraocular lens (IOL) or a single-piece 4 haptics IOL. RESULTS A total of 263 eyes from 242 patients were included in the study. Postope...
