PURPOSE To evaluate the safety and efficacy of corneal collagen crosslinking (CXL) for the treatment of progressive keratoconus. DESIGN Prospective, randomized, multicenter, controlled clinical trial. PARTICIPANTS Patients with progressive keratoconus (n = 205). METHODS The treatment group underwent standard CXL and the sham control group received riboflavin alone without removal of the e...

Objective: To determine the reliability and agreement of different optical devices in terms keratometry pachymetry measurements cross-linked (CXL) keratoconic eyes. Material Methods: Thirty-eight CXL-treated eyes were evaluated. Three repeated performed with Topcon KR-1 autorefractokeratometry, Sirius topography, Nidek AL-scan biometry RTVue anterior segment coherence tomography (AS-OCT). The c...

Period: March 2017 to October 2019. Material & Methods: All patients suffering from were included study after consent. Proper proforma was designed for record. Detail history taken diagnosis all properly exami...

PURPOSE To compare the 1-year results of total versus partial epithelium removal in corneal cross-linking in the treatment of progressive keratoconus. METHODS This retrospective study compared the results of total (the total group) versus partial (the partial group) approaches of epithelium removal in corneal cross-linking. Eighty eyes of 65 patients (40 eyes in each group) were enrolled. The...

AIM To compare the axial eye length growth of the two fellow eyes within one patient after unilateral paediatric cataract surgery and to assess changes in refraction and keratometry. PATIENTS/METHODS A retrospective study in 90 eyes of 45 patients was performed. The 45 patients were divided into group 1 (patients younger than 18 months at the time of surgery, n=25) and group 2 (patients 18 mont...

A bnormalities of emmetropisation, resulting most often in myopia, have long been independently associated by numerous authors from nearly every corner of the globe with increasing prematurity, increasing severity of retinopathy of prematurity (ROP), and retinal ablative therapy. This topic has also been the subject of an editorial in the BJO in 1997, the substance of which remains true today. ...

Aim. The aim of this study was to determine the intra- and interobserver variability of two Scheimpflug based camera systems, Pentacam and Sirius. In addition, the comparability of the measurements was tested in healthy subjects, subjects with regular astigmatism, and keratoconus patients. Methods. Intra- and interobserver variability were assessed in 20 healthy corneas. Pachymetry values were ...

Abstract To evaluate the repeatability and agreement of corneal biometry measurements obtained with two swept-source optical coherence tomography (SSOCT) a partial interferometry-based device. This is cross-sectional study. Forty-eight eyes 48 patients had three consecutive for ANTERION (Heidelberg Engineering, Germany), CASIAII (Tomey, Japan) IOLMaster500 (Carl Zeiss Meditec, USA) on same visi...
