Abstract

Purpose : To report the 12 month outcomes of 194 eyes undergoing corneal cross-linking for keratoconus performed in routine clinical practice across Australia and New Zealand.

Methods : Index visit characteristics, such as visual acuity (VA, in Logarithm of the Minimal Angle of Resolution [logMAR] letters), maximum keratometry [Kmax], pachymetry, as well as treatment parameters (epithelial status, riboflavin type, UV duration), outcomes (VA, Kmax, pachymetry) and ocular adverse events were recorded in a prospectively designed electronic database. Index visit characteristics associated with the 12-month VA outcome were identified using mixed effects linear regression.

Results : Mean change in VA in the cohort after 12 months was +3.1 logMAR letters (95% confidence interval [CI]: -0.9, 5.3); Kmax +0.1 D (95% CI: -0.3, 0.5) and pachymetry -14.9 microns (95% CI: -21.0, -8.6). There was no significant difference in change in Kmax (p = 0.649); a significant improvement in VA (p = 0.006) and reduction in pachymetry was found at 12 months (p < 0.001). VA at the index visit was the strongest predictor of the 12-month VA outcomes (p < 0.001). Treatments were epithelial-off (n=178) with UV exposure that was accelerated (n= 118) or according to the Dresden protocol (n=60). Adverse events episodes occurred in 15 eyes and included clinically significant haze (n=22), microbial keratitis (n=1), persistent epithelial defect (n=2), scarring (n=6) and sterile infiltrates (n=2) from a total of 194 eyes within the first 12 months of follow-up.

Conclusions : The Keratoconus module of the Save Sight Registries can facilitate the collection of large amounts of data on corneal cross-linking. The finalised 12 month outcome data has shown that corneal cross-linking can stabilize visual acuity and corneal parameters when used in routine clinical practice.
