Actual Indications for Intracorneal Ring Segment Implantation in Keratoconus
Intracorneal ring segments (ICRS) are small synthetic implements designed to achieve refractive adjustment by flattening the cornea. Three common types of commercially available ICRS are Intacs, Keraring and Ferrara rings. Low myopia was the initial indication for implantation of ICRS, and indications later included ectatic corneal diseases (such as keratoconus and pellucid marginal degeneratio...
متن کاملContact lenses fitting after intracorneal ring segments implantation in keratoconus.
PURPOSE Evaluate contact lenses fitting after intracorneal ring implantation for keratoconus, its visual acuity and comfort. METHODS Retrospective study of patients undergoing contact lenses fitting, after intracorneal ring for keratoconus. The criterion for contact lens fitting was unsatisfactory visual acuity with spectacle correction as referred by the patients. All patients were intoleran...
متن کاملQuantitative OCT-based longitudinal evaluation of intracorneal ring segment implantation in keratoconus.
PURPOSE To characterize the geometrical properties of keratoconic corneas upon intracorneal ring segments (ICRS) implantation, using custom-developed optical coherence tomography (OCT). METHODS Ten keratoconic corneas were measured pre- and post-ICRS surgery (7, 30, and 90 days). Corneal topographic and pachymetric maps were obtained from three-dimensional (3D) images acquired with OCT, provi...
متن کاملIntracorneal ring segment in keratoconus: a model to predict visual changes induced by the surgery.
PURPOSE We detected keratoconus cases with a significant potential for poor outcomes following intracorneal ring segment implantation (ICRS). We attempted to predict the potential of a case in terms of gain or loss of corrected distance visual acuity (CDVA). METHODS In this retrospective and prospective, consecutive, nonrandomized, multicentric study, 58 keratoconic eyes (aged 1756) were impl...
متن کاملEffect of Conus Eccentricity on Visual Outcomes After Intracorneal Ring Segments Implantation in Keratoconus.
PURPOSE To investigate the potential impact of cone eccentricity on visual outcomes after Keraring (Mediphacos, Belo Horizonte, Brazil) implantation for keratoconus. METHODS Nineteen eyes from 19 patients with keratoconus who underwent femtosecond laser-assisted Keraring implantation for keratoconus were included in this retrospective study. Uncorrected visual acuity (UDVA), corrected visual ...
