Purpose: To report our experience with Descemet stripping only (DSO) for the treatment of Fuchs endothelial corneal dystrophy. Methods: Thirteen eyes 9 patients symptomatic dystrophy underwent a 4 mm central Descemetorhexis without graft implantation between June 2017 and July 2020. All had confluent guttata, undetectable cell count by specular microscopy, healthy peripheral endothelium. In 6 eyes, procedure was combined phacoemulsification intraocular lens implantation. Eight were treated...
Purpose To develop a model for predicting postoperative keratometry in children undergoing cataract surgery with primary intraocular lens (IOL) implantation. Methods The longitudinal retrospective study included all who underwent bilateral and had available intraoperative data. Variables that could influence were analyzed, generalized estimating equation regression was used to predict keratometry. Results One hundred twenty eyes of 60 included. mean age at 2.95 ± 2.78 years (range: 0.12...
To compare the performance of a self-refraction device (EyeQue Vision Check 2, EyeQue, USA) with autorefraction (OPD-Scan III, NIDEK) and subjective cycloplegic refraction in measuring refractive errors. This descriptive study included 80 eyes from 40 patients. Measurements were obtained using portable EyeQue device, OPD-Scan performed by an experienced examiner. Spherical equivalent (SE), cylindrical power, axis values analyzed power vector decomposition (M, J0, J45) to improve accuracy...
Purpose: To describe the outcomes of corneal transplantation after minimally invasive neurotization (MICN) in pediatric patients. Methods: Medical records all children who underwent post-MICN with sural nerve graft for neurotrophic keratopathy between 2015 and 2021 were reviewed retrospectively. Data collected included demographic information, ocular comorbidities, maximum sensitivity by Cochet–Bonnet aesthesiometer (CBA) preoperatively postoperatively measured central area, survival...
Purpose: To compare the refractive predictability of intraoperative aberrometry (IA, ORA, Alcon) and Barrett True-K/Universal II formulas for intraocular lens (IOL) power calculations in post-corneal surgery normal eyes. Methods: Retrospective study eyes that underwent cataract with IA at tertiary academic center. Preoperatively, IOL were performed using Universal (normal eyes) or True-K (post-corneal formulas. Intraoperatively, aphakic measurements used calculations. Mean absolute...
To report clinical outcomes and surgical technique of flanged intrascleral intraocular lens fixation with double-needle combined either penetrating keratoplasty (PKP) or ultrathin Descemet-stripping automated endothelial (UT-DSAEK).Five patients underwent keratoplasty. Three triple procedure (open sky PKP) secondary to ocular trauma a failed corneal transplant. Two UT-DSAEK for pseudophakic bullous keratopathy (PBK) anterior chamber (AC IOL).Flanged PKP was shown be safe effective method...
Purpose: The purpose of this study was to report a case “smoldering” keratolimbal allograft (KLAL) rejection in patient with subtherapeutic levels systemic immunosuppression temporal association BNT162b2 messenger RNA vaccination for severe acute respiratory syndrome coronavirus 2. Methods: This report. Observations: A 72-year-old man presented circumferential perilimbal engorgement, stagnation, and tortuosity vessels mild chemosis his right eye KLAL segments 1 month after receiving the...
Purpose: To assess optical quality dynamics using a double-pass (DP) system in patients with dry eye disease (DED). Methods: Seventy-six eyes DED and 44 control subjects were enrolled this study. Each patient underwent ocular surface evaluation including fluorescein corneal staining Schirmer's II test. Ocular Surface Disease Index (OSDI) questionnaire was used to subjective symptoms. Optical tear film instability analyzed DP (HD Analyzer TM , Visiometrics, Spain). Mean objective scatter...
The purpose of this study was to evaluate 5-year safety and efficacy outcomes femtosecond-enabled Descemet membrane endothelial keratoplasty (F-DMEK) in patients with Fuchs' dystrophy (FED).This a retrospective study, including FED cataract who underwent either F-DMEK (16 eyes 15 patients) or manual DMEK (M-DMEK) (42 37 combined extraction. Outcome measures included visual acuity, graft detachment, survival, cell loss.The average follow-up M-DMEK 57.1 ± 12.4 months 58.5 17.3 months,...
Abstract Objective: The objective of the study was to evaluate impact dry eye treatment on intraocular lens (IOL) biometry measurements and postoperative refractive outcome. Design: This involves a prospective interventional study. Participants: Consecutive patients with disease undergoing cataract surgery were included in Materials Methods: All participants underwent comprehensive assessment including ocular surface index (OSDI) questionnaire, Schirmer’s test without anesthesia, corneal...
PURPOSE: To compare ray-tracing aberrometry, Hartmann-Shack wavefront analysis, automated refraction, and manifest refraction in patients with echelette diffractive intraocular lenses (IOLs) monofocal IOLs negative spherical aberration. METHODS: Pseudophakic implanted an IOL (Tecnis ZXR00; Johnson & Vision) a control group consisting of aberration ZCBOO, were included this study. Ray-tracing aberrometry (iTrace; Tracey Technologies Corp.), analysis (LADARWave; Alcon Laboratories, Inc.),...
Purpose: To investigate outcomes of femtosecond laser (FL)-assisted cataract surgery (FLACS) and refractive lens exchange (RLE) in patients with prior radial keratotomy (RK). Setting: Single clinical practice. Design: Retrospective observational case series. Methods: All RK undergoing FLACS- or FL-assisted RLE surgeries over a 6-year period were reviewed. Inclusion criteria diurnal stability stable manifest refraction. Exclusion any other incisional corneal surgery, macular glaucomatous...
To evaluate the prediction of postoperative anatomical lens position (ALP) using intraoperative spectral-domain optical coherence tomography (SD-OCT) anatomy metrics in patients who underwent femtosecond laser-assisted cataract surgery.Intraoperative SD-OCT (Catalys; Johnson & Vision) and biometry (IOLMaster 700; Carl Zeiss Meditec AG) were used to assess anterior segment landmarks, including thickness, volume, chamber depth, meridian (LMP), measured ALP. LMP was defined as distance from...
Purpose: The success of Descemet stripping only (DSO) is optimized by performing a well-centered, accurately sized diameter descemetorhexis with smooth curvilinear border. To achieve this success, we describe repeatable and relatively straightforward technique to optimize for DSO. Methods: “two-flaps” uses the Gorovoy DSO forceps. takes advantage flat surface forceps create desired 4-mm minimal stromal trauma along continuous descemetorhexis, minimizing risk postoperative scarring extension...
To report clinical outcomes of a patient with unilateral neurotrophic keratitis following penetrating keratoplasty for lattice dystrophy treated topical recombinant human nerve growth factor.A 75-year-old male and history herpes simplex keratitis, presented recurrent ulceration in the right eye two years keratoplasty. The was successfully factor.Neurotrophic is rare chronic disorder that affects quality life due to risk vision loss. Topical factor novel effective treatment option may help...
