AIM To evaluate the efficacy and safety of phacoemulsification using torsional modality with different parameter settings for hard nucleus cataract extraction. DESIGN A prospective, randomised clinical study. METHODS A clinical practice study conducted at the Cataract Service, Zhongshan Ophthalmic Center, Sun-Yat-Sen University, and Guangzhou. One eye each from 198 consecutive patients with...

Surgically induced diffuse scleritis (SIDS) is a recognised but less well reported cause of pain and reduced vision following cataract surgery. We have previously reported on complications of conventional extracapsular cataract extraction in which SIDS was the second most common. Recently, we conducted an audit of patients who underwent phacoemulsification cataract extraction to compare the inc...

PURPOSE To evaluate anatomic and functional results after surgery of retained lens fragments in the vitreous cavity after previous phacoemulsification. METHODS The authors studied retrospectively 18 patients who underwent pars plana vitrectomy (PPV) for retained nuclear lens fragments. Patients having only cortical material in the vitreous cavity were excluded. In all cases the nucleus or nuc...

Methods: Retrospective chart review of residentperformed phacoemulsification cases at the Atlanta Veterans Affairs Medical Center, Decatur, Georgia, from July 1, 1999, through June 30, 2002. Outcomes measured included postoperative uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), intraoperative complications, and adjusted phacoemulsification times (total phacoem...

The phacoemulsification surgery is one of the most advanced surgeries to treat cataract. However, the conventional surgeries are always with low automatic level of operation and over reliance on the ability of surgeons. Alternatively, one imaginative scene is to use video processing and pattern recognition technologies to automatically detect the cataract grade and intelligently control the rel...

BACKGROUND To evaluate the efficiency and practicality of femtosecond laser assisted cataract surgery (FLACS) in a public teaching hospital setting using a mobile FLACS system compared to conventional phacoemulsification cataract surgery (CPCS). METHODS Ninety eyes from 90 patients underwent either FLACS or CPCS (45 in each group). Cataracts were graded using the Lens Opacities Classification...
