Purpose: To analyze the rate of inadvertent anterior lens capsular tears with vitrectorhexis or continuous curvilinear capsulorhexis (CCC) in pediatric cataract and intraocular lens (IOL) implantation surgery between January 1, 1997, and December 31, 2006.
Methods: Retrospective chart review, collecting for each eye: age at cataract surgery, type of anterior capsulotomy, any tearing of the capsule, and if yes, details of the tear.
Results: A total of 737 eyes were reviewed.
We compared the pediatric anterior capsulotomy preferences of members of the American Society of Cataract and Refractive Surgery (ASCRS) and the American Association of Pediatric Ophthalmology and Strabismus (AAPOS) reported in 3 surveys (1993, 2001, and 2003). In 1993 and 2001, more than 50% of ASCRS respondents preferred manual anterior capsulotomy techniques; in 2001 and 2003, AAPOS respondents preferred manual and vitrector techniques. The ASCRS preferences remained unchanged when subdivided into domestic and international, as did AAPOS domestic preferences; however, more than 50% of AAPOS international preferences changed from manual alone in 2001 to a manual-vitrector combination in 2003.

Methods: A total of 93 eyes of 52 subjects were evaluated preoperatively between 1 January and 31 March 2003, using a Hartmann-Shack-based aberrometer. Age, gender, cycloplegic refraction, pupil size, keratometry readings, anterior chamber depth, white-to-white tests, intraocular pressure and basic secretion tests were evaluated.

Purpose: The aim of this study was to determine the vitreous brimonidine concentration of topically applied brimonidine-Purite 0.15%.
Methods: Patients scheduled for a pars plana vitrectomy were invited to participate in this study after institutional review board (IRB) approval was obtained.
Purpose: To compare the extensibility and scanning electron microscopy (SEM) of 5 currently used pediatric anterior capsulotomy techniques: vitrectorhexis, manual continuous curvilinear capsulorhexis (CCC), can-opener, radio frequency diathermy, and plasma blade in a porcine model.
Setting: Storm Eye Institute, Medical University of South Carolina, Charleston, South Carolina, USA.
Methods: Extensibility was determined by stretching each capsulotomy until it ruptured and measuring it by calculating the mean stretch-to-rupture circumference of each capsulotomy (20 eyes per technique) as a percentage of its baseline circumference.
Purpose: The aim of this study was to investigate the prophylactic use of 0.3% gatifloxacin drops to prevent endophthalmitis in a rabbit model.
Methods: Forty (40) New Zealand white rabbits were randomly placed into group A (20 rabbits) where they received 1 drop of 0.
Purpose: To determine outflow resistance of the Baerveldt glaucoma implant using different tube configurations.
Methods: Outflow resistance of 6 tube configurations (C1- C6) of Baerveldt implants was measured under conditions of constant pressure perfusion. Pressures ranged from 2 to 55 mm Hg.
To determine the refractive surgery preferences of ophthalmologists worldwide, questionnaires were sent to 8920 members of the American Society of Cataract and Refractive Surgery. A total of 1174 questionnaires was returned by the deadline. The practice distribution included 30.

Methods: A retrospective review of 29 eyes of 20 patients receiving a hydrophobic acrylic (AcrySof; Alcon, Fort Worth, TX) IOL implantation was conducted. All eyes underwent primary posterior capsulectomy and anterior vitrectomy.
A survey of pediatric cataract surgery and intraocular lens (IOL) implantation practice patterns of adult and pediatric cataract surgeons was performed in October 2001. Questionnaires were distributed to the American Society of Cataract and Refractive Surgery and the American Association for Pediatric Ophthalmology and Strabismus. The overall return rate was 12.

Other ocular findings include glaucoma, corneal opacity (keloid), enophthalmos, and hypotonia.
Objective: To describe the treatment of 7 patients (14 eyes) with bilateral cataracts associated with oculocerebrorenal syndrome.
