Purpose To compare the efficacy of phakic intra-ocular lenses in isolation or in combination
with corneal crosslinking (CXL) and/or intra-stromal corneal ring segments (ICRS) in …

Methods In the past, a diagnosis was derived from clinical symptoms, but technological
advances have revealed multiple pre-clinical features, allowing for the differentiation …

Purpose: To assess the preoperative visual, refractive, corneal topo/tomographic,
aberrometric and biomechanical parameters as predictive factors of a successful outcome 6 …

Background: The aim of this study was to analyze the long-term topographic and refractive
outcomes of corneal cross-linking (CXL) in keratoconus. Methods: We used a retrospective …

Purpose The main aim of the study was to report visual, refractive, topographic, and
aberrometric results of accelerated CXL in patients with keratoconus who were followed for …

Purpose: High-order aberrations (HOAs) have been demonstrated to profoundly affect both
visual acuity and stereoacuity in patients with keratoconus. Corneal collagen cross-linking …

角膜高阶像差(corneal higher-order aberration, HOA), 是由于角膜的非理想球面产生的一种
不能被框架眼镜矫正的复杂光学畸变, 可导致患者的视觉质量下降. 目前, 角膜HOA …

Objectives: This study was designed to evaluate the effects of corneal collagen cross-linking
(CXL) on topographic parameters, visual acuity, and corneal high-order aberrations …

Materials and Methods: In this cross-sectional study, 67 patients with keratoconus referred to
Farshchian Sina Medical Education Center, Hamadan, Iran, who underwent CXL surgery at …

Results Preoperative and postoperative 1-month Root Mean Square (RMS) of the total HOA
differences was statistically insignificant with P value of 0.102, however, preoperative and …
