A child suffering from traumatic cataract and corneal astigmatism of 2.14 D had a phacoemulsification operation and implantation of a ReSTOR Toric intraocular lens (IOL) to correct the astigmatism. The primary outcome measurements were the uncorrected distance visual acuity (UDVA), uncorrected near vision at 40 cm, intraocular pressure, spherical equivalent refraction, residual astigmatism, corneal astigmatism, presence of unusual optical phenomena, and use of spectacles. At 7 months postoperatively, UDVA was maintained between 16/20 and 24/20, near vision was between J1 and J3, residual spherical refraction was 0-0...

PURPOSE: Klotho genes are expressed in limited tissues and have been found to be a pathogenic factor of age-related diseases in mammals, but their expressions and functions in human eyes are yet to be defined. This study was performed to investigate the expression of Klotho family genes in human ocular tissues and anterior lens capsules of age-related cataract. METHODS: Individual tissues were isolated from human eyeballs collected from Henan Eye Bank. Human anterior lens capsules were collected from cortical cataract patients during phacoemulsification with the informed consent...

INTRODUCTION: Epiretinal membranes (ERM) have been increasingly characterized with the advent of new optical coherence tomographies (OCTs). We intended to perform a systematic review regarding prognostic factors (PF) of ERM after surgery. MATERIALS AND METHODS: Systematic review of electronic databases was performed (last date of search was 10 August 2015): Medline, Scopus, Google Scholar, clinicaltrials.gov and current controlled trials. Search queries included: "membrane", "pucker", "prognosis", "prognostic", "epiretinal", "épirétinienne"...

PURPOSE: To compare the shape of the capsulotomy, its change, and its impact on visual quality over 1 year using the femtosecond laser system from the manual technique. METHODS: In this two-center cross-sectional study from May 2012 to June 2013, each patient had femtosecond laser-assisted cataract surgery in one eye (FLACS group) and conventional phacoemulsification cataract surgery in the other eye (CPCS group). An evaluation of the capsulotomy was performed using retroillumination slit-lamp photographs at 7 days, 6 months, and 1 year after surgery...

A 25-year-old man suffered an isolated lens anterior capsular tear and mature cataract formation following blunt injury to his right eye. One week after the trauma, best-corrected visual acuity (BCVA) in the right eye was hand motion. B-scan ultrasonography showed that the lens posterior capsule was intact; no vitreous foreign body or retinal pathology were observed. Orbital computed tomography revealed narrowed anterior chamber and increased lens material volume and lens reflectivity in the injured right eye...

A 56-year old female patient presented to our clinic with a complaint of low vision in her right eye. Twenty-two years earlier she had undergone a scleral buckling operation in her right eye because of retinal detachment. She indicated that vision in her right eye was good after the surgery but had recently been gradually declining. Best-corrected vision acuity was counting fingers at 1 meter in the right eye and 8/10 in the left eye. Anterior segment examination revealed stage 3 nuclear cataract in the right eye...

BACKGROUND: Antifibrotic agents are commonly utilized to enhance the success rates of trabeculectomy. Novel approaches to further improve success rates and reduce the risks of complications are needed. The purpose of this study was to compare intraocular pressure (IOP)-lowering efficacy and safety of trabeculectomy or combined phacoemulsification and trabeculectomy with mitomycin-C (MMC) vs. Collagen Matrix (CM). METHODS: A prospective, multicenter, randomized controlled trial was performed...

Phacoemulsification followed with intraocular lens (IOL) implantation is the most effective clinical surgeries in treating cataracts. However, posterior capsular opacification (PCO), a common complication of this surgery, may cause vision decrease after surgery. PCO is mainly caused by the adhesion, proliferation and trans-differentiation of the residual lens epithelial cells (LEC) after surgery. Surface modification of IOL to reduce the LEC adhesion is of great importance in PCO prevention. Herein, surface initiated reversible addition-fragmentation chain transfer (SI-RAFT) polymerization was utilized to modify the IOL materials for generating a comb-like polyethylene glycol (PEG) brush coating on the surface...

PURPOSE: To determine the potential role of intraoperative dexamethasone intravitreal implant (DEX-I) in reducing diabetic macular edema (DME) worsening after phacoemulsification. METHODS: This was a prospective study on 19 eyes of 19 patients with type 2 diabetes mellitus with DME and cataract. Mean preoperative Early Treatment Diabetic Retinopathy Study visual acuity (VA) was 16.7 letters. Mean foveal thickness (FT) was 451 μm. The DME was naive in 11 eyes and refractory in 8 eyes...

: We report a case of anaphylactic shock following topical administration of moxifloxacin for endophthalmitis prophylaxis prior to cataract surgery. Immunoglobulin E (IgE) serology and IgE skin testing confirmed the anaphylactic etiology. Phacoemulsification with posterior chamber intraocular lens implantation was later performed with identical preoperative preparation except for the exclusion of moxifloxacin; no anaphylactic response occurred. To our knowledge, this is the first report of an anaphylactic response to topical moxifloxacin...
