Brief Summary:
To our knowledge, this study is one of the first to compare the visual results of non-topography-guided and topography-guided photorefractive keratectomy (PRK) applying sequential and simultaneous corneal cross-linking (CXL) treatment for keratoconus. Considering recent advances in cross-linking and imaging in keratoconus, the outcomes of this study can lead us to several non-invasive algorithm management options.
Detailed Description:
Interventional and comparative prospective study: Sixty-nine eyes (38 patients) suffering from keratoconus (stages 1-2 Amsler-Krumeich classification) were divided into four groups. The four groups underwent topography- and non-topography-guided PRK with sequential and simultaneous CXL. The main outcome measures were pre- and postoperative uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (CDVA), manifest refraction, contrast sensitivity, and keratometry.
