Outcomes of Cataract Surgery Complicated by Retained Lens Fragments Requiring Pars Plana Vitrectomy.

Objective: To analyze outcomes and complications related to cataract surgery complicated by retained lens fragment (RLF) requiring pars plana vitrectomy (PPV) in a county hospital where procedures are performed by trainees.

Methods: Retrospective study of consecutive patients who met inclusion criteria and underwent PPV for RLF in the vitreous cavity at an urban teaching hospital between January 2010 and January 2016 (N=20).

Main Outcomes/measures: Visual acuity was recorded pre- and post-operatively over a follow-up period of 3 to 12 months.

Band keratopathy in children previously treated with diode laser for type 1 retinopathy of prematurity.

Band keratopathy is a corneal degeneration caused by chronic inflammation, systemic abnormalities, or, rarely, a primary biallelic SLC4A4 mutation leading to calcium hydroxyapatite deposition in Bowman's layer. We report a series of 16 eyes of 10 children with a remote history of diode laser treated retinopathy of prematurity who developed late-onset band keratopathy without evidence of other prior risk factors. The majority of patients developed band keratopathy bilaterally.

Etiology and treatment outcomes of persistent postoperative inflammation in primary resident-performed cataract surgeries at a large tertiary care public hospital.

Purpose: To determine the risk factors, intraoperative and postoperative complications, therapeutic interventions, and visual outcomes for persistent postoperative inflammation in primary resident-performed cataract surgeries.

Setting: Ben Taub General Hospital, Houston, Texas, USA.

Design: Retrospective case series.

Outcomes and complication rates of primary resident-performed cataract surgeries at a large tertiary-care county hospital.

Purpose: To identify the preoperative risk factors, intraoperative events, and postoperative complications increasing the risk for poor visual outcomes in resident-performed cataract surgeries at a tertiary-care county hospital.

Setting: Ben Taub General Hospital, Houston, Texas, USA.

Design: Retrospective case series.

Comparison of corneal power, astigmatism, and wavefront aberration measurements obtained by a point-source color light-emitting diode-based topographer, a Placido-disk topographer, and a combined Placido and dual Scheimpflug device.

Purpose: To evaluate and compare the performance of a point-source color light-emitting diode (LED)-based topographer (color-LED) in measuring anterior corneal power and aberrations with that of a Placido-disk topographer and a combined Placido and dual Scheimpflug device.

Setting: Cullen Eye Institute, Baylor College of Medicine, Houston, Texas USA.

Design: Retrospective observational case series.

Contribution of posterior corneal astigmatism to total corneal astigmatism.

Purpose: To determine the contribution of posterior corneal astigmatism to total corneal astigmatism and the error in estimating total corneal astigmatism from anterior corneal measurements only using a dual-Scheimpflug analyzer.

Setting: Cullen Eye Institute, Baylor College of Medicine, Houston, Texas, USA.

Design: Case series.
