Abstract

Purpose: To study the efficacy and safety of PRK and corneal cross linking (CXL) For treatment
of suspicious and early Keratoconus. Methods: fifty eyes of thirty two patients with suspicious
and early keratoconus were included. all patient underwent Simultaneous PRK and corneal
cross linking (CXL) The outcomes were evaluated at 18 months in all eyes. Result: 80 %
percent of UNCVA postoperatively are equal to preoperatively BCVA or gained 1 or more lines
20 % only Lost 1 line, 62 % of the eyes are within 1.0D. of emmetropia. None of the eyes had >
2.0 D and 54 % of the eyes had Astigmatism by K-Reading within 1.0D. None of the eyes had >
2.0D. Conclusion: We concluded that The Combined non-topographyñguided PRK and CXL is
an effective procedures for correcting mild refractive error and improving visual acuity and
safety option for arresting the ectatic progression, with improvement of corneal keratometric
values in patients with suspicious and early keratoconus provided that we adhere to the
selection criteria of that we recommend. However, future studies with larger cohorts of patients
and longer follow-up periods are needed to determine the safety, efficacy, and stability of such
procedure.
