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 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 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 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 ...
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...
