Clinical Trial Summary

There is no standard of care medication regimen for the management of pain and inflammation post-corneal crosslinking (CXL), although most cornea specialists agree on use of an antibiotic and steroid eye drop in the immediate postoperative period. However, steroid tapering schedule and use of additional topical non-steroidal anti-inflammatory (NSAID) eyedrops vary amongst practitioners. The goal of this study is to compare postoperative pain scores between patients receiving a tapering dose of topical steroids over 1-month post-CXL, versus those receiving an intracanalicular dexamethasone insert.


Clinical Trial Description

Keratoconus is a progressive ectatic disease of the cornea, leading to worsening of astigmatism and vision over time. With FDA approval of corneal collagen cross-linking (CXL), we now have the ability to halt the progression of keratoconus and prevent further vision loss in these patients. Although CXL has now become standard of care, the immediate post-operative period can be quite painful despite use of anti-inflammatory medications/eye drops. The goal of this study is to evaluate the efficacy of an intracanalicular dexamethasone insert in reduction of post-CXL pain as compared to routine steroid eye drop therapy. To date, no studies have been performed evaluating the success of an intracanalicular dexamethasone insert for the treatment of postoperative inflammation and pain in corneal cross-linking patients. Oftentimes, patients experience a great deal of discomfort post-CXL, which may also make it difficult to apply eye drops in the correct fashion. Use of a dexamethasone insert alleviates the need for postoperative steroid eye drops and may provide increased pain relief post-CXL as compared to topical therapy. This will be a head-to-head study where steroid therapy (topical or insert) will begin in a standard fashion on the date of CXL. This will allow for accurate comparison of a 4-week taper of topical steroids, versus a dexamethasone insert designed to release steroid for 30 days. ;
