AIM To evaluate the use of accelerated corneal collagen cross-linking in the management of mild and moderate progressive keratoconus in comparison with conventional cross-linking. PATIENTS AND METHODS Prospective randomized interventional case-control clinical trial. A total 25 eyes of 18 patients were randomly divided into two groups: group A included 14 eyes that received accelerated collag...

PURPOSE To determine whether preoperative, postoperative, or change in keratometry can be used to predict visual outcomes in hyperopic LASIK. METHODS A retrospective analysis was conducted on hyperopic eyes treated at Optical Express clinics. All eyes were targeted for emmetropia and treated using wavefront-guided LASIK (VISX S4, Abbott Medical Optics [AMO]), with flaps created using a femtos...

AIMS To compare methods available to correct the magnification of images that result from the optics of the eye and identify errors, and source of error, of the methods. METHODS 11 methods were applied to ocular biometry data from three independent cohorts. Each method was compared with the method of Bennett, which uses most biometric data. The difference between each method and Bennett's is ...

PURPOSE To evaluate the long-term clinical effectiveness and safety of corneal collagen cross-linking (CXL) in progressive keratoconus compared with untreated contralateral eyes. METHODS In this retrospective study, nine eyes of nine patients with progressive keratoconus who received CXL (treatment group) and nine untreated contralateral eyes with keratoconus (control group) were included. Al...

AIM To determine the induced corneal astigmatism by measuring the changes in manual keratometry and computerised corneal videokeratoscopy up to 1 year following small flap trabeculectomy (microtrabeculectomy). METHOD A prospective study of a case series of small flap trabeculectomy procedures performed at the 90 degree meridian on 16 eyes of 16 patients, all followed to 1 year postoperatively...

One hundred cases of uncomplicated cataract with clear corneae had cataract extraction and were examined at 20 days and six weeks after operation. Keratometry was done preoperatively and keratometry and retinoscopy at each of the follow-up visits. The study was undertaken to evaluate the type (whether pre- or postplaced) and the number of sutures (one, three, or five) that produce the least pos...

PURPOSE To survey the standard keratoconus grading scale (Pentacam®-derived Amsler-Krumeich stages) compared to corneal irregularity indices and best spectacle-corrected distance visual acuity (CDVA). PATIENTS AND METHODS Two-hundred and twelve keratoconus cases were evaluated for keratoconus grading, anterior surface irregularity indices (measured by Pentacam imaging), and subjective refract...
