PURPOSE: There are no reported large series of trabeculectomy with mitomycin-C (MMC) in Western patients with primary angle-closure glaucoma (PACG). Our study evaluates long-term tonometric outcomes of trabeculectomy in PACG. METHODS: This is a retrospective cohort study. The primary outcomes were the Kaplan-Meier success rates on survival analyses using three criteria, with or without adjunctive medication: (A) intraocular pressure (IOP) ≤18▒mmHg and IOP reduction of 20%; (B) IOP≤15▒mmHg and IOP reduction 25%; and (C) IOP≤12▒mmHg and IOP reduction 30%...

REVIEW
Gaëlle Ho Wang Yin, Louis Hoffart
Postoperative visual acuity can be limited by post-keratoplasty astigmatism, even with a clear corneal graft. Astigmatism management can be performed by selective suture removal, adjustment of sutures, optical correction, photorefractive procedures, wedge resection, intra-ocular lens implantation, intracorneal ring segments, relaxing incisions with or without compression sutures and repeated keratoplasty. Relaxing incisions can be made in the graft, graft-host interface or host cornea. Despite the unpredictability of the method because the flat and steep meridians are usually not orthogonal after penetrating keratoplasty, with asymmetric power distribution, all the studies showed an overall reduction of refractive, keratometric or topographic astigmatism, ranging from 30% to 72% with manual or femtosecond-assisted techniques...

Lenticular changes are often seen following electrical injury. We report an unusual case of electrical injury with late spontaneous posterior dislocation of lens nucleus with intact anterior capsule with ruptured posterior capsule in the right eye and anterior subcapsular cataract in the left eye. The right eye was managed with pars plana vitrectomy with cortical matter removal with multipiece intraocular lens insertion in ciliary sulcus. This report adds posterior capsular rupture and posterior dislocation of lens to the usual ocular complications of electrical injury...

BACKGROUND: The purpose of this paper is to report the first use of an intraocular lens (IOL) in an astronaut during long duration spaceflight (LDSF). An astronaut developed a unilateral cataract and underwent phacoemulsification with insertion of an acrylic IOL. Approximately 15 mo later he flew on a Soyuz spacecraft to the International Space Station (ISS), where he successfully completed a 6-mo mission. CASE REPORT: Ocular examination, including ultrasound (US), was performed before, during, and after his mission and he was questioned regarding visual changes during each portion of his flight...

PURPOSE: To assess the influence of decentration and aperture size on the optical quality of different intraocular lenses (IOLs) of the same material, body design, and refractive power using standardized optical bench testing. METHODS: Using an optical bench set-up, an aspheric monofocal (CT ASPHINA 409M; Carl Zeiss Meditec, Jena, Germany), an aspheric diffractive bifocal (AT LISA 809M; Carl Zeiss Meditec), and an aspheric diffractive trifocal (AT LISA 839M; Carl Zeiss Meditec) intraocular lens (IOL) were evaluated, each with the same distance power, body design, and material...

PURPOSE: To determine whether use of a capsular tension ring (CTR) can increase refractive stability in patients with implantation of two different trifocal intraocular lenses (IOLs). METHODS: A prospective, consecutive series of eyes underwent refractive lens exchange with implantation of two different trifocal IOL designs: FineVision Micro F (non-toric) and FineVision POD FT (toric) (PhysIOL, Liege, Belgium). Power calculation was determined using the Haigis formula...

PURPOSE: To compare the prediction error in the calculation of toric intraocular lenses (IOLs) associated with methods that estimate the power of the posterior corneal surface (ie, Barrett toric calculator and Abulafia-Koch formula) with that of methods that consider real measures obtained using Scheimpflug imaging: a software that uses vectorial calculation (Panacea toric calculator: http://www.panaceaiolandtoriccalculator.com) and a ray tracing software (PhacoOptics, Aarhus Nord, Denmark)...

A 58-year-old woman with bilateral Fuchs endothelial corneal dystrophy presented with predominantly central guttata in the left eye causing visually significant stromal edema. A 4.0 mm descemetorhexis without endothelial keratoplasty was performed. At the 6-week follow-up, the central cornea had cleared completely and the central endothelial cell density (ECD) was 541 cells/mm2. The central corneal clearing remained stable for 2 years after the procedure; however, vision declined because of a visually significant cataract in the left eye...

A 28-year-old woman had uneventful implantation of a phakic intraocular lens (pIOL) in her left eye (Visian ICL, EVO+ model, 13.2, -7.50 diopters) to correct myopia. Six days after the procedure, she presented with herniation of the iris. Surgical reduction was carried out successfully through the previous peripheral corneal paracentesis. On the following day, the patient reported ocular pain and blurry vision. Examination showed a shallow anterior chamber, moderate diffuse corneal edema, and ocular hypertension...

Background: Dropped lens fragments into the vitreous are uncommon, but potentially sight threatening complications of cataract surgery. The recommended approach for removal of dropped lens matter is pars plana vitrectomy with or without ultrasonic emulsification with the fragmatome. This study aimed to determine the visual outcome following pars plana vitrectomy for dropped lens fragments complicating cataract surgery at 6 weeks, 3 months and 6 months. Methods: This study is a retrospective review of patients who had PPV as treatment for dropped lens fragments complicating cataract surgery at Ispahani Islamia Eye hospital and Institute...

BACKGROUND: Intraoperative IOLs clouding of several kinds of hydrophilic acrylic intraocular lenses (IOLs) have been reported due to temperature changes. This phenomenon reported previously occurred in cold countries and during the winter months. However, no clinical case was reported about trifocal IOL opacification during operation. We report a case in which acute opacification of the optical region occurred simultaneously when AT LISA tri 839mp(Carl Zeiss) was implanted into the eye...

Hydrogen sulfide (H2S) is a gaseous transmitter with well-known biological actions in a wide variety of tissues and organs. The potential involvement of this gas in physiological and pathological processes in the eye has led to several in vitro, ex vivo, and in vivo studies to understand its pharmacological role in some mammalian species. Evidence from literature demonstrates that 4 enzymes responsible for the biosynthesis of this gas (cystathionine β-synthase, CBS; cystathionine γ-lyase, CSE; 3-mercaptopyruvate sulfurtransferase, 3MST; and d-amino acid oxidase) are present in the cornea, iris, ciliary body, lens, and retina...

A 23-year-old female patient presented 3 months after the implantation of an Artisan® phakic intraocular lens with a severe depigmentation of the iris and peripheral anterior synechiae. Explantation of the intraocular lens and goniosynechialysis were performed. Eleven months after the explantation appearance of the iris significantly improved. There was no loss of lines of corrected distance visual acuity. Severe pigment dispersion after the implantation of an Artisan® phakic intraocular lens may happen and may require explantation of the lens...

A 55-year-old female with an aphakic nanophthalmic eye underwent a secondary intraocular lens implantation (IOL) with double Artisan aphakia iris claw IOLs (ICIOLs) and was evaluated in this research. The patient's preoperative best-corrected visual acuity (BCVA) of the right eye was 0.4 (0.4 logMAR) (with + 21.00 D), postoperative 1st and 3rd month, 1st year, and 3 years BCVAs were 0.4 (0.4 logMAR). The intraocular pressure was 15 mmHg preoperatively, and 14, 12, 12, and 15 mmHg postoperatively at 1st and 3rd month, 1st year, and 3 years, respectively...
