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...
Background and Objective: Evaluation of the results, safety, and stability of ferrara intracorneal ring segment (FICRS) implantation for Keratoconus correction (age range was 24.39±8.32 years). Materials and Methods: In this clinical trial study, 64 eyes of 57 patients with keratoconus and clear cornea that had FICRS implantation were studied. Uncorrected visual acuity (UCVA), best-spectacl...
OBJECTIVE To compare visual, refractive, and corneal aberrometric outcomes in keratoconic eyes implanted with intracorneal ring segments (ICRS) implantation using either a mechanical or a femtosecond laser-assisted procedure. DESIGN Retrospective, consecutive case series. PARTICIPANTS A total of 146 consecutive eyes of 106 patients with the diagnosis of keratoconus (68 unilateral and 39 bil...
INTRODUCTION Corneal thinning disorders caused by keratoconus often lead to protrusion, irregular astigmatism, and even perforation. Keratoconus, like other corneal ectasia, does not have a known cause. Severe cases of keratoconus may require correction or restoration of tectonic integrity of the cornea by surgical means. Intracorneal ring segments are a new modality in the treatment of corneal...
