Clinical evaluation of two types of intracorneal ring segments (ICRS) for keratoconus.

Purpose: To compare the outcome measures following implantation of two types of ICRS.

Methods: Forty-four eyes of keratoconic patients (aged 18-50 years) were randomly assigned to femtosecond laser-assisted Keraring ICRS (Group A) or MyoRing (Group B) implantation. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, keratometry (K), and aberrations were compared preoperatively, at 3 and 6 months postoperatively.

Agreement Between Autorefraction and Subjective Refraction in Keraring-Implanted Keratoconic Eyes.

Objectives: To assess the agreement between subjective refraction and autorefraction and to explore the relationship between the magnitude of higher order aberration, and visual acuity and refraction, before and after keraring implantation.

Methods: This prospective, randomized, interventional study enrolled 27 subjects (mean age 28.1±6.

One-Year Clinical Outcomes of a Two-Step Surgical Management for Keratoconus-Topography-Guided Photorefractive Keratectomy/Cross-Linking After Intrastromal Corneal Ring Implantation.

Purpose: To present the results of same-day topography-guided photorefractive keratectomy (TG-PRK) and corneal collagen cross-linking (CXL) after intrastromal corneal ring (ISCR) implantation in patients with keratoconus.

Methods: Thirty-three patients (41 eyes) aged between 19 and 45 years were included in this prospective study. All patients underwent a femtosecond laser-enabled (Intralase FS; Abbott Medical Optics, Inc.

Visual rehabilitation in low-moderate keratoconus: intracorneal ring segment implantation followed by same-day topography-guided photorefractive keratectomy and collagen cross linking.

Aim: To present the results of same-day topography-guided photorefractive keratectomy (TG-PRK) and corneal collagen crosslinking (CXL) after previous intrastromal corneal ring segment (ISCR) implantation for keratoconus.

Methods: An experimental clinical study on twenty-one eyes of 19 patients aged 27.1±6.

Intracorneal 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 patients first underwent femtosecond laser-enabled placement of ICRS (Keraring, Mediphacos) (first step).
