Intracorneal Rings Followed by Photorefractive Keratectomy With Corneal CXL: 2-Step Approach for Moderate Keratoconus
Purpose
To select the right keratoconus patient for intra corneal rings (ICR), to observe post-op results for 6-12 months, to enhance post-ICR results with photorefractive keratectomy (PRK) with corneal cross-linking (CXL) and to review the results of this approach.
Methods
Twelve patients (eyes) with moderate KC were selected with strict selection criteria, underwent ICR insertion followed by CXL combined with PRK to stop the progression of ectasia and improve patient’s quality of vision.
Results
Difference between pre-ICR and post-PRK +CXL for UNCVA was 0.61, For BCVA was 0.19, for spherical equivalent (S.E.) was -4.88D, for corneal astigmatism was -1.9D, for max K was 6.25D. For average K was 5.88D and for coma was 0.98.
Conclusion
Based on our review, ICR followed later by PRK+CXL is an effective and safe approach in making a functional change in the life style of cases of moderate KC. We recommend to be done for a selected group of moderate KC patients.
