Abstract Details

Purpose:

The purpose of our study was to evaluate results of contact lens (CL) fitting after corneal cross-linking (CXL) in eyes with progressive keratoconus.

Setting:

The medical records of 15 patients who underwent CXL for progressive keratoconus and wear CL in postoperative period were retrospectively reviewed.

Methods:

Progressive keratoconus was defined as the presence of at least one of the following conditions; ≥ 1 diopters (D) increase in the steepest keratometry, ≥ 0.5 D increase in spherical or cylindrical values in manifest refraction and ≥ 1 -line decrease in best corrected visual acuity (BCVA) in the Snellen chart. CL examination was performed after a minimum of 3 months after CXL. BCVA with spectacles and CL, corneal topographic data before and after treatment, properties of the fitted CL, duration of CL wear, and CL-related problems were recorded.

Results:

Twenty-one eyes of 15 patients (7 female, 8 male) with a mean age of 17.7 ± 4.9 were included in the study. No progression was observed in any patient during follow-up (mean 2.7 ± 1.5 years). Twelve eyes were fitted with RGP CL, 8 eyes were fitted with soft silicone-hydrogel keratoconus CL and 1 eye was fitted with soft toric CL after CXL. None of the eyes were able to wear CL successfully before CXL. However, 16 eyes (76%) continued to wear CL successfully after CXL during follow-up. BCVA increased in 20 (95%) eyes with CL wear after CXL.

Conclusions:

CL may be a good option in visual rehabilitation after CXL. Performing of CXL is important in progressive keratoconus in terms of stopping progression, increasing CL adaptation and preventing rapid changes in CL parameters.
