Abstract

Purpose : To identify factors associated with uncorrected distance visual acuity (UDVA) outcome 1 year after corneal collagen crosslinking (CXL) treatment in patients with progressive keratoconus.

Methods : A retrospective cohort study was carried out in a high referral ophthalmology centre in Mexico City. Data was collected from medical charts of patients who attended the Cornea Service from 2010 to 2015 with a diagnosis of progressive keratoconus and had undergone crosslinking. Basic demographic information, topographic and refractive data, visual acuity outcomes and, complications were obtained. A total of 191 eyes were included. Predictive factors for analysis included: age, sex, preoperative uncorrected visual acuity, best-corrected visual acuity, steep keratometry, corneal central pachymetry, refractive sphere and, cylinder.

Results : Thirty eyes (50.7 %) have a change of less than 1 line of UDVA, 22 eyes (32.8%) gained 1 line or more and, 11 eyes (16.4%) lost 1 line or more. After a multivariable analysis no factor was found to be associated with postoperative UDVA after 1 year of CXL. Complications reported were pain in 22 cases (15.7%) and haze in 5 eyes (2,6%). No other complications were reported.

Conclusions : No preoperative factors associated with UDVA outcome were found in this study after 1 year of CXL. Other factors that might be involved in the visual prognosis of CXL need to be analyzed
