PURPOSE To evaluate visual outcomes in moderately myopic eyes with flat and steep corneas (preoperatively) that have been treated with laser-assisted in situ keratomileusis (LASIK). PATIENTS AND METHODS Records of ninety-six eyes with average preoperative keratometry (K) values between 39.9 and 42.0 diopters (D) (flat) were matched with 103 eyes with preoperative K values between 46.0 and 47....

BACKGROUND The aim of this study was to evaluate the efficacy and safety of transepithelial corneal collagen crosslinking (transepithelial CXL) versus standard corneal collagen crosslinking (epithelium-off CXL) on keratoconus. METHODS Eligible studies were identified by systematically searching PubMed, the Cochrane Library and Embase. Topographic parameters, corrected distant visual acuity (C...

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...

PURPOSE To investigate corneal thickness, curvature, and morphology with the Orbscan Topography System I (Bausch & Lomb, Inc., Salt Lake City, UT) in patients with Marfan syndrome (MFS) and to study MFS with in vivo confocal microscopy. METHODS This prospective, clinical, comparative case series included 60 eyes of 31 patients with MFS and 32 eyes of 17 control subjects. First, biomicroscopic...

Objectives: To find out the prevalence and severity of keratoconus in spring catarrh patients. Study Design: Descriptive Perspective study. Setting: OPD K.D.A Teaching Hospital Kohat. 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...

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...

Objective: To determine the difference in mean corneal curvatures before and after pterygium excision, by using automated refraction and keratometry. Methodology: This quasi-experimental study was conducted at Eye Unit-I, Bahawal Victoria Hospital, Bahawalpur, from March 2010 to August 2010. Thirty patients with primary pterygium were analyzed before and after pterygium surgery for corneal curv...

BACKGROUND Keratoconus typically presents in the teenage years and is more advanced in younger patients when compared with adults. In the present study, we aimed to assess the safety and efficacy of accelerated transepithelial corneal collagen cross-linking (ATE-CXL) in children with progressive keratoconus. METHODS In this retrospective consecutive study, 18 eyes were enrolled from 17 pediat...
