Summary
This trial will compare two procedures for treating keratoconus, a degenerative eye disease. One procedure uses a collagen crosslinking, while the other uses Intacs. The goal is to determine which procedure is more effective.
Who is the study for?
This trial is for adults over 21 with keratoconus or corneal ectasia, not perfect vision (worse than 20/20), and specific topography changes. It's not for those with other eye conditions that could complicate treatment, thin corneas at certain measurements, pregnant or lactating individuals, known drug sensitivities, or healing issues.
What is being tested?
The study tests the effectiveness of combining two treatments—corneal collagen crosslinking (CXL) and Intacs inserts—for keratoconus and corneal ectasia. One group receives both treatments in one session; another has CXL three months after Intacs to compare results.
What are the potential side effects?
Potential side effects may include discomfort in the eye, visual disturbances like halos or glare, dry eyes, infection risk increase post-procedure. The severity can vary from person to person.
