Pur6pose To detect epithelial thickness-based diagnostic variables to detect early keratoconus (KC) and differentiate cases of early KC from high regular astigmatism, especially if abnormal topographic changes are present. Patients and methods A total of 84 eyes with high regular astigmatism on Scheimpflug imaging were evaluated by anterior segmen...

Background A safe alternative to excimer laser in fixing high myopia is the implantable phakic contact lens (IPCL). Cycloplegics have been found to produce vault changes in the implantable collamer lens but not tested yet for the IPCL. Purpose To analyze central vault changes linked with instillation of cyclopentolate in myopic IPCL implanted pati...

Purpose The aim of this study was to determine the effectiveness of a novel innovative monofocal intraocular lens (Tecnis Eyhance ICB00) compared with the standard monofocal lens (Tecnis-1-piece ZCB00) in terms of contrast sensitivity, postoperative refraction, intermediate visual acuity (VA), and uncorrected and best-corrected distance VA. Patien...

Purpose To study the effect of neodymium-doped yttrium aluminum garnet (Nd : YAG) laser posterior capsulotomy on refraction and best-corrected visual acuity in pseudophakic eyes. Patients and methods This retrospective nonrandomized analytic study included 110 eyes (n=100 patients) with posterior capsular opacification following a phacoemulsificati...

Purpose To evaluate differences in the subjective aniseikonia and stereoacuity in patients with axial anisometropia after full correction of the refractive error with spectacles, contact lenses, and refractive surgery. Methods A prospective study was performed in Cairo University Hospitals on 20 patients with axial anisometropia caused by unilater...

Purpose To report the prevalence of subclinical keratoconus (KC), and KC suspects, in pediatric Egyptian population with astigmatic error ≥2 diopters (D), with the use of CSO Sirius tomographer. Methods A cross-sectional study that included all the children aged 6–18 years with an astigmatic error of ≥2 D who attended the pediatric ophthalmology c...

PURPOSE: To assess Visian Implantable Collamer Lens (ICL) (STAAR Surgical, Monrovia, CA) implantation in the ciliary sulcus to correct pseudophakic ametropia in patients who are not candidates for a keratorefractive procedure. METHODS: The authors performed a prospective non-comparative case series study of 18 patients (age: 48 to 61 years) with re...

Purpose To evaluate femtosecond laser in DSAEK surgery as an improvement to manual DSAEK. Settings Department of Ophthalmology, Cairo University. Design A retrospective observational clinical study. Methods 20 eyes with SBK and Fuchs' dystrophy underwent a Femto-assisted DSAEK by laser cutting of two matching posterior stromal discs in the recip...

Purpose: To evaluate retinal sensitivity in children who are on hydroxychloroquine (HCQ) for systemic lupus erythematosus using microperimetry and compare the results with those of the Humphrey visual field (HVF) 10-2 and spectral-domain optical coherence tomography (SD-OCT). Procedure: A case-control cross-sectional study including 19 patients...

Purpose: To assess the safety and efficacy of intravitreal infliximab (1 mg/0.05 mL) in patients with refractory posterior uveitis in Behcet's disease. Methods: Twenty patients were included in this study. Best corrected visual acuity (BCVA), vitreous haze (graded 0-4), vasculitis, retinitis, and papillopathy (presence or absence) were assessed...

Purpose To compare complete versus incomplete ring implantation for keratoconus correction. Methods We investigated 25 eyes of keratoconic patients, of which 15 had femtosecond-assisted MyoRing corneal implantation (Group 1) and 10 had femtosecond-assisted Keraring segments (Group 2). Uncorrected distance visual acuity (UCVA), best corrected dista...
