Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals with non-ectatic corneas who have high cylinder errors.
✕Probably not a fit
Patients with corneal ectasia will not benefit from this study as they are excluded from participation.

What this trial studies
This study focuses on the implantation of INTACS, which are intra-corneal rings, to correct high cylinder errors in patients with non-ectatic corneas. The approach aims to improve visual acuity and reduce the need for corrective lenses in individuals suffering from significant astigmatism. The methodology involves a surgical procedure where these rings are placed within the cornea to reshape its curvature. The study seeks to evaluate the effectiveness and safety of this intervention for the targeted patient population.
Why it matters
Potential benefit: If successful, this intervention could significantly improve vision for patients with high cylinder errors, enhancing their quality of life.
How similar studies have gone: While there may be limited data on this specific approach, similar interventions using intra-corneal rings have shown promise in correcting refractive errors.
