WHAT WAS KNOWN
*Standard CXL is the common procedure for treating progressive corneal ectasia. Modifications of the standard protocol were introduces to reduce its complications especially long exposure to ultraviolet rays. The Accelerated protocol, while believed to overcome this issue with comparable outcomes, has not been studied fully in patients with ectasia following corneal refractive surgery and penetrating keratoplasty.
WHAT THIS PAPER ADDS Accelerated CXL is as safe and effective as the Standard CXL in halting the progression of ectasia post refractive surgery and penetrating keratoplasty with the benefit of: reduced ultraviolet exposure, reduced operation time, and reduced patient discomfort.
Full description
Purpose:
The aim of this study is to compare the clinical outcomes of the Standard CXL and the AC CXL in patients with progressive corneal ectasia post refractive surgery and penetrating keratoplasty.
Setting:
Menoufia University Hospital, Egypt
Design:
Prospective, randomised comparison.
Methods:
Patients scheduled to receive either Standard CXL (3mW/cm2 for a period of 30 min) or Accelerated CXL (18mW/cm2 for a period of 5 min).The main outcomes for comparison were the change in; Maximum-K reading (K-max), manifest refractive spherical equivalent (SE), central corneal thickness (CCT), and the best corrected distance visual acuity (CDVA).
