Corneal Asphericity Changes after Implantation of Intrastromal Corneal Ring Segments in Keratoconus
Keratoconus is a progressive corneal thinning of unknown cause in which the cornea assumes a conical shape, with progressive irregular astigmatism and deterioration of visual acuity. The normal anterior corneal surface is prolate, and it could be described as conic (flattening of the radius of curvature from the apex toward the periphery)1. In keratoconus corneas, the steepening of the central ...
متن کاملVisual, Keratometric and Corneal Biomechanical Changes after Intacs SK Implantation for Moderate to Severe Keratoconus
PURPOSE To report visual outcomes and corneal biomechanical changes after femtosecond-assisted Intacs SK implantation in keratoconic eyes. METHODS This prospective interventional case series is comprised of 32 keratoconic eyes of 25 patients with mean age of 23.8 ± 5.4 years. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, refraction, manifest refraction spherical equivalent (...
متن کاملPrediction of Corneal Condition After Corneal Ring Implantation in Keratoconus Patients
Background: Keratoconus is a common complication among corneal defects. As a result of expeditious and extensive progress of medical science in recent decades, corneal ring implantation has turned into a successful surgical procedure to correct the vision of Keratoconus patients; however, selecting the right patient is essential in the success of the operation. The prediction of corneal conditi...
متن کاملConfocal biomicroscopic changes of the corneal layers following femtosecond laser-assisted MyoRing implantation in keratoconus
PURPOSE To evaluate the effect of the femtosecond laser-assisted MyoRing implantation on the confocal biomicroscopic findings in different corneal layers of the patients with keratoconus. METHODS Twelve eyes of 12 patients with mild to moderate keratoconus (keratometry between 48 and 52 diopters) and intolerance to hard contact lens entered the study. All the included patients underwent femto...
متن کاملChanges in corneal asphericity after laser in situ keratomileusis.
PURPOSE To analyze the origin of the changes in corneal asphericity (p-factor) after laser in situ keratomileusis (LASIK) and the effect of postsurgery asphericity on contrast-sensitivity function (CSF) under photopic conditions. SETTING Department of Optics, University of Granada, Granada, Spain. METHODS The p-factor and CSF (best corrected before surgery and 1, 3, and 6 months after surge...
