Corneal Collagen Cross‐Linking for Keratoconus: Systematic Review

BioMed Research International, Volume 2017, Issue 1, 2017., 2017
Purpose. To evaluate the efficacy of collagen cross‐linking (CXL) one year after treatment for keratoconus compared to no treatment by summarizing randomized controlled trials (RCTs) using a systematic review. Methods. Trials meeting the selection criteria were quality appraised, and the data were extracted by two independent authors.

Oxidative stress induces dysregulated autophagy in corneal epithelium of keratoconus patients. [PDF]

PLoS ONE, 2017
Oxidative stress is one of the key factors that contributes to the pathogenesis of keratoconus (KC). Macroautophagy is a vital cellular mechanism that is activated in response to oxidative stress.

Outcomes of photorefractive keratectomy in patients with atypical topography

, 2017
Background: Photorefractive keratectomy (PRK) is at risk of serious complications such as corneal ectasia, which can reduce corrected distance visual acuity. The rate of complications of PRK is higher in patients with atypical topography.
