PURPOSE: The aim of this study was to determine the correlation between ocular biometric parameters and sulcus-to-sulcus (STS) diameter. METHODS: This was a cross-sectional study of preoperative ocular biometry data of patients who were candidates for phakic intraocular lens (IOL) surgery. Subjects underwent ocular biometry analysis, including refraction error evaluation using an autorefractor and Orbscan topography for white-to-white (WTW) corneal diameter and measurement...

Purpose: To report a case of bilateral iridoschisis with cataracts and corneal decompensation in a patient who underwent cataract extraction and superficial iridectomy followed by Descemet membrane endothelial keratoplasty (DMEK). Observations: A 58-year-old man with previously diagnosed iridoschisis, cataracts, and diabetes mellitus experienced progressive vision loss bilaterally due to corneal decompensation. Slit lamp examination revealed iridoschisis with iris fibrils contacting the corneal endothelium, stromal edema, and mild guttate changes bilaterally...

Despite the use of modern methods of prevention, at least 10% of patients operated on for ophthalmic indications not develop corneal erosion as the indirect complication of general anesthesia. OBJECTIVE: To reduce the number of ophthalmic complications of general anesthesia by prophylactic use of new mito- chondria-targeted antioxidants - Vizomitin (eye drops). MATERIALS AND METHODS: 70 patients, which was supposed to perform the average duration of operations under general anesthesia were randomized into 3 groups depending on the method specific (pharmacological) prevention of corneal erosions: (1) control (specic (pharmacological) prevention was not carried out), (2), using preparation "natural tear, and (3) "Vizomitin" preparation...

Fungal keratitis is a severe and common ocular infectious disease. The present study evaluated the efficiency of full-thickness conjunctival flap covering surgery with amniotic membrane transplantation (FCCS + AMT) as a transitional surgery for severe fungal keratitis. A total of 17 patients with severe fungal keratitis without corneal perforation underwent FCCS + AMT between January 2010 and December 2015. The pathogenic factors, preoperative diagnosis and postoperative prognosis of FCCS + AMT at 3 months were evaluated...

BACKGROUND: Torsional mode phacoemulsification results in more effective fragmentation of the nucleus due to a different movement of the phacotip. In this clinical study, we investigated the influence of a modified tip design and active fluidics on the efficacy of phacoemulsification and safety for the corneal endothelium. MATERIAL AND METHODS: We conducted a prospective randomized 2 : 1 study in which 40 patients were operated on with the mini-flared Kelman Tip using the Infiniti ® System (group 1), and 20 patients were operated on with the Intrepid ® Balanced Tip and the Centurion ® System...

PURPOSE: Posterior capsule opacification (PCO) still represents the main long-term complication of cataract surgery. Research into pharmacologic PCO prophylaxis is extensive. One promising candidate drug is methotrexate (MTX). Our aim is to determine the in vitro feasibility of MTX-loaded poly(lactic-co-glycolic) (PLGA) biomatrices sprayed on intraocular lenses (IOLs) as a drug-delivery implant. METHODS: Hydrophilic and hydrophobic acrylic IOLs were spray-coated with MTX-loaded PLGA...

Purpose: To evaluate the accuracy of IOL power calculation using adjusted corneal power according to the posterior/anterior corneal curvature radii ratio. Methods: Nine hundred twenty-eight eyes from 928 reference subjects and 158 eyes from 158 cataract patients who underwent phacoemulsification surgery were enrolled. Adjusted corneal power of cataract patients was calculated using the fictitious refractive index that was obtained from the geometric mean posterior/anterior corneal curvature radii ratio of reference subjects and adjusted anterior and predicted posterior corneal curvature radii from conventional keratometry (K) using the posterior/anterior corneal curvature radii ratio...

Aim. To study the outcome of cataract surgery in eyes with pseudoexfoliation without signs of glaucoma. Methods. This prospective study was done over nine months on patients with pseudoexfoliation undergoing small incision cataract surgery. Only patients with normal intraocular pressure (Central Corneal Thickness Corrected), normal cup disc ratio and open angles were included. Patients on anti-glaucoma medication were excluded. Patients underwent surgery performed by a single senior surgeon. Intraoperative and postoperative day (POD) 1 findings were noted...

The authors present five cases of bilateral corneal disorders, on which they performed penetrating keratoplasty. All five patients were clinically blind and after the surgery on one eye, they gained their visual independence. Visual acuity, intraocular pressure, fundus examination, and ultrasonography were used to evaluate the patients before and after the surgery.

Pseudophakic bullous keratopathy is characterized by corneal stromal edema with epithelial and subepithelial bullae due to cell loss and endothelial decompensation through trauma during cataract surgery. Patients present decreased vision, tearing, and pain caused by ruptured epithelial bullae. Cataract affects approximately 20 million people worldwide, and this complication can occur in 1 to 2% of the cataract surgeries. This study reviewed the bullous keratopathy etiopathogenesis and the clinical and surgical treatment available for this corneal disease...

Background: Mitomycin C (MMC) as an alkylating agent is miscellaneous an antineoplastic, antibiotic and ophthalmic agent. Here we aim to report a case of inadvertent intravitreal MMC injection instead of Avastin in case of diabetic macular edema. Case presentation: A 53 years old woman was planned to receive intravitreal Avastin injection, but accidentally, 0.05 ml of MMC 0.2% was injected. Best corrected visual acuity (BCVA) was 20/160 before injection. After 2 days, patient was referred to a tertiary referral eye center...

PURPOSE: The purpose of this study was to evaluate the 5-year clinical results of isolated Bowman layer (BL) transplantation in the treatment of advanced keratoconus. METHODS: In this prospective, single-center, interventional case series at a tertiary referral center, 20 eyes of 17 patients with advanced keratoconus underwent BL transplantation, i.e. an isolated Bowman layer graft was positioned into a manually dissected mid-stromal pocket. Scheimpflug-based corneal tomography measurements, best corrected spectacle and contact lens visual acuities (BSCVA and BCLVA), endothelial cell density, and complications were evaluated up to 5 years after surgery...

PURPOSE: Cataract surgery has been reported to adversely affect the IOP control in eyes with the glaucoma drainage implant (GDI). One reason might be the flow of lens debris/viscoelastic material through the GDI tube into the bleb. This pilot study was conducted to determine the clinical results of a novel technique for temporary occlusion of the GDI tube with an iris retractor hook during phacoemulsification. METHODS: Retrospective analysis of 15 patients (control group) who underwent phacoemulsification between January 2005 and December 2010 and 17 patients (treatment group) who underwent phacoemulsification with the hooked tube technique between January 2011 and April 2016 with a minimum 1-year follow-up...
