TL;DR
A patient with keratoconus developed unexpected corneal ectasia after a standard corneal cross-linking procedure, highlighting potential risks and gaps in current understanding.
Contribution
Reports the first known case of corneal ectasia following epi-off cross-linking in keratoconus.
Findings
Corneal ectasia occurred post-CXL despite adherence to standard protocols.
The case suggests possible limitations in current diagnostic tools and treatment protocols.
Emphasizes the need for improved patient screening and follow-up.
Abstract
Description of an unusual ectasia following corneal cross-linking (CXL) in a patient with keratoconus. Clinical case report and review of the literature. We present a case of an unusual ectasia after corneal CXL in a patient with keratoconus. This case reports the first known occurrence of corneal ectasia following epi-off CXL, a procedure typically used to halt the progression of ectatic disorders such as keratoconus. Although the standard protocol was followed, subtle technical variations or postoperative healing factors could have contributed to the outcome. This case underscores the need for ongoing vigilance in patient selection and follow-up in the context of CXL. The rare development of corneal ectasia post-CXL highlights a gap in our understanding of corneal biomechanics and the potential limitations of current diagnostic tools. More research is needed to refine patient…
