Abstract
Photorefractive keratectomy (PRK) is a common procedure for correction of refractive errors. Corneal collagen crosslinking (CXL) is a procedure used to strengthen a weakened ectatic cornea and is mainly used as a therapeutic procedure in keratoconus (KC) patients, to prevent deterioration and improve visual acuity. PRK-CXL combination performed simultaneously or sequentially, has been suggested in KC patients to provide improved visual acuity, in addition to halting the ectatic progression. Our case was a patient with KCN and visual deterioration that underwent accelerated CXL with good results and 1 year later, his right eye was subjected to PRK due to anisometropia. The patient achieved an uncorrected visual acuity of 10/10 without any complications for both eyes. Our good results suggest that PRK-CXL combination might be considered for correction of decreased visual acuity and anisometropia in patients with KCN. However, more studies are required to further evaluate the surgical outcome and safety of this procedure.
