Quantitative OCT-based corneal topography in keratoconus with intracorneal ring segments
Custom high-resolution high-speed anterior segment spectral domain Optical Coherence Tomography (OCT) was used to characterize three-dimensionally (3-D) corneal topography in keratoconus before and after implantation of intracorneal ring segments (ICRS). Previously described acquisition protocols were followed to minimize the impact of the motions of the eye. The collected set of images was cor...
متن کاملFerrara intracorneal ring segments for keratoconus.
PURPOSE To assess the outcome of Ferrara intracorneal ring segments for keratoconus. SETTING Private practice and university hospital, Porto Alegre, Brazil. METHODS In this retrospective noncomparative interventional case series, 51 keratoconus eyes of 47 patients that had Ferrara intracorneal ring segment implantation were reviewed. Uncorrected visual acuity (UCVA), best spectacle-correcte...
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 segments implantation followed by same-day topography-guided PRK and corneal collagen CXL in low to moderate keratoconus.
PURPOSE To evaluate the safety and efficacy of intrastromal corneal ring segments (ICRS) implantation followed by same-day topography-guided photorefractive keratectomy (PRK) and ultraviolet-A/riboflavin collagen cross-linking (CXL) in patients with low to moderate keratoconus. METHODS Patients with low to moderate keratoconus and contact lens intolerance were included in the study. All patie...
متن کاملIntacs Intracorneal Ring Segments Complications in Patients Suffering from Keratoconus
Intacs, intrastromal corneal rings are widely used to reduce myopia, astigmatism, keratometry readings and high order aberrations in patients suffering from keratoconus, almost 15 years have passed from the first procedure which was performed in the eye of a patient with unsatisfactory visual acuity and contact lenses intolerance. Many publications including book chapters, retrospective studies...
