Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To join established study put on by Addition Technologies, Inc. in the surgical implantation of asymmetrical INTACS segments to treat myopia and astigmatism in patients with keratoconus.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Use of asymmetrical corneal inserts to reduce or eliminate myopia and astigmatism in patients with keratoconus, who are no longer able to achieve adequate vision with their contact lenses or spectacles, so that their functional vision may be restored and the need for corneal transplantation may potentially be deferred.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria
