Trial Summary

What is the purpose of this trial?This trial is testing special contact lenses for people with severe vision issues that regular lenses can't fix. These custom-made lenses use advanced eye measurements to improve vision quality by correcting specific distortions.

Eligibility Criteria

This trial is for individuals with keratoconus or irregular astigmatism, which are conditions that distort vision. Participants must be able to apply and remove scleral lenses themselves and should not have other major eye diseases affecting their sight.

Inclusion Criteria

I have been diagnosed with keratoconus or irregular astigmatism.

Exclusion Criteria

I have an eye condition that significantly affects my vision.

I cannot put in or take out a scleral lens by myself.

Participant Groups

The study is comparing two types of contact lenses: Wavefront Guided Scleral Lenses designed to correct specific visual aberrations, versus Traditional Scleral Lenses that help improve vision but may not address all issues caused by higher order aberrations.
