Intrastromal corneal ring segment implantation for ectasia after refractive surgery.
PURPOSE To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct ectasia in eyes with prior refractive surgery. METHODS Forty-one eyes of 25 patients (13 men, 12 women; mean age, 28.66 years) with ectasia after refractive surgery [photorefractive keratectomy (PRK) or laser in situ keratomileusis (LASIK)] were included in a nonrandomized, retrospect...
متن کامل[Analysis of corneal curvature alteration following intrastromal corneal ring implantation: experimental study in rabbits].
PURPOSE To evaluate the effect of intrastromal corneal ring implantation on corneal curvature in rabbits. METHODS Thirty eyes of 15 rabbits were divided into two groups: group 1 with 7 animals and group 2 with 8 animals. The left eye underwent surgery and the right eye was used as control. Ultrasound pachymetry and corneal topography were performed prior to surgery. Anterior segment biomicros...
متن کاملCorneal 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 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 کاملIntrastromal corneal ring segment implantation for the treatment of keratoconus.
PURPOSE To evaluate the safety and efficacy of intrastromal corneal ring segment implantation using both mechanical and femtosecond-assisted tunnel creation for the treatment of patients with keratoconus. METHODS A retrospective noncomparative interventional study including 96 eyes of 75 patients with keratoconus. All patients had contact lens intolerance and clear central corneas. Corneal tu...
