OBJECTIVE: To assess the effect of lens status and cataract surgery on glaucoma drainage device (GDD) efficacy. DESIGN: Retrospective cohort study. SUBJECTS: 243 eyes of 216 patients that underwent GDD implantation with ≥ one follow-up visit within 3-years postoperatively. Exclusion criteria included GDD combined with other ophthalmic procedures. 90-94% of GDDs were Ahmed implants; 83-90% had adjunctive mitomycin-C. METHODS: Outcomes were compared between phakic eyes (group A), eyes phakic at time of implantation but subsequently underwent cataract surgery within three years (group B), and pseudophakic eyes (group C)...

We describe a novel technique that uses precision pulse capsulotomy (PPC) to perform a secondary capsulotomy for the management of anterior capsule contraction syndrome (ACCS), a condition that comprises a late complication after cataract surgery and intraocular lens (IOL) implantation. Micropulse secondary capsulotomy offers a controlled and safe approach for patients with severe anterior capsule contraction syndrome and may be considered as an alternative surgical technique.

BACKGROUND AND OBJECTIVE: We describe an in-office lens repositioning technique for anterior crystalline lens dislocation. PATIENTS AND METHODS: We present a case series of four patients with spontaneous or traumatic anterior crystalline lens dislocation. RESULTS: The technique included supine patient positioning, gentle pressure with a cotton swab on the peripheral cornea to guide the lens into the posterior chamber, and the use of a miotic agent afterward to prevent subsequent subluxation...

PURPOSE: This study was undertaken to evaluate the safety and efficacy of CSF-1 (0.4% pilocarpine hydrochloride ophthalmic solution) for use in individuals with presbyopia. METHODS: Two Phase 3 multicenter, randomized, double-masked, vehicle-controlled, parallel-group clinical trials were conducted in 35 private ophthalmology clinics in the United States from October 2020 to February 2022. Key inclusion criteria were the following: (1) age 45-64 years, (2) distance-corrected near visual acuity (DCNVA) at 40 cm ≥0...

To demonstrate the results of ray tracing higher- and lower-order aberrations in pseudophakic eyes with rotationally asymmetrical segment multifocal lenses, total high- and low-order aberrations, measured by root mean square value (RMS), refraction, uncorrected distance and uncorrected near visual acuity (UCDVA and UCNVA), and tear break-up time, were measured at scotopic size in 42 eyes of patients implanted with bifocal refractive Mplus15/Mplus30 IOL with +1.5 dpt near addition (42 eyes of patients implanted with Mplus15)/+3...

BACKGROUND: The authors sought to determine if resident operative time in cataract extraction and intraocular lens insertion (CE/IOL) affects early visual outcomes and post-operative recovery. They further sought to investigate if attending surgeons can reduce resident operative time. METHODS: This retrospective, chart-review, case series at single Veterans Affairs Hospital (VA Tennessee Valley Healthcare System) studied resident cataract surgeries between March 1, 2018 and March 31, 2020...

PURPOSE: Retinal capillary hemangioblastoma (RCH) is present in about half of the carriers of the VHL (von Hippel-Lindau) gene mutation and can lead to the evolution of blindness. Herewith is a proposal for surgical intraretinal feeder vessel ligature to induce ischemia the phakoma and to resolve the exudative secondary retinal detachment, with satisfying results at the 6 months follow-up end point. METHODS: The patient underwent a chandelier-assisted 23 G pars plana vitrectomy with valved trocars...

AIMS: To establish and evaluate predictive models for glaucoma-related adverse events (GRAEs) following secondary intraocular lens (IOL) implantation in paediatric eyes. METHODS: 205 children (356 aphakic eyes) receiving secondary IOL implantation at Zhongshan Ophthalmic Center with a 3-year follow-up were enrolled. Cox proportional hazard model was used to identify predictors of GRAEs and developed nomograms. Model performance was evaluated with time-dependent receiver operating characteristic (ROC) curves, decision curve analysis, Kaplan-Meier curves and validated internally through C-statistics and calibration plot of the bootstrap samples...

PURPOSE: Iridocorneal endothelial (ICE) syndrome may cause refractory glaucoma due to progressive synechial closure or membrane formation at the anterior chamber angle. Filtration surgeries are often required but are associated with a higher rate of surgical failure or complications than other types of glaucoma. Herein, we report a new and effective surgical procedure for glaucoma secondary to ICE syndrome: Ex-PRESS shunt combined with ab-interno peripheral iridectomy using a small-gauge vitreous cutter...

BACKGROUND A Sömmering ring is a post-cataract opacity (PCO) formed due to the adhesion of anterior capsule edges to the posterior capsule. It is mostly associated with aphakic cases but has also been reported in pseudophakic eyes. It becomes clinically important when dislocation occurs. The purpose of this manuscript was to report a case of anterior dislocation of the Sömmering ring 14 years after lensectomy for congenital cataract. CASE REPORT We describe a 20-year-old man who presented to the emergency room with pain, photophobia, redness, and blurry vision in the right eye...

We included consecutive cases with rhegmatogenous retinal detachment (RRD) treated with vitrectomy and silicone oil tamponade, and subsequent secondary IOL implantation during silicone oil removal between September 2019 and June 2022...

INTRODUCTION: We present a unique case of iris chafing syndrome in a patient with a complex ophthalmologic history after successful placement of a single-piece in-the-bag intraocular lens (IOL) in an eye with healthy zonular support. CASE PRESENTATION: A patient with a previous history of multiple retinal surgeries presented with pain and elevated intraocular pressure (IOP) secondary to retained viscoelastic material in the anterior chamber. Following removal of the viscoelastic material in clinic, the patient underwent a combined cataract and glaucoma surgery...

OBJECTIVES: Iris-claw intraocular lens (IC-IOL) implantation and sutureless scleral fixation of intraocular lenses (SSF-IOL) are two commonly preferred surgical approaches for the management of aphakic patients without sufficient capsular support. The aim of this study was to compare the outcomes of IC-IOL implantation and trocar-assisted SSF-IOL implantation. METHODS: The medical records of secondary IOL implantation patients were retrospectively reviewed. All patients had a detailed ophthalmological examination, including LogMAR best-corrected distance visual acuity (CDVA), intraocular pressure (IOP), and endothelial cell density (ECD) preoperatively and postoperatively...
