Brief Summary

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

This study will evaluate the outcomes of placing preserved corneal tissue within the keratoconic cornea in order to enhance thickness, stability, and optical conformation.

Detailed Description

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

The objective of this study is to evaluate the outcomes of placing preserved corneal tissue within the corneal stroma in keratoconus patients as a means of enhancing thickness, stability, and optical conformation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Corneal tissue inlay

The treated cornea will be implanted with a thin disc of preserved corneal tissue

Group Type EXPERIMENTAL

Corneal tissue inlay

Intervention Type PROCEDURE

A mid-stomal pocket will be made into the cornea with a femtosecond laser (Intralase). A small disc of preserved corneal tissue will then be placed into the pocket

Eligibility Criteria

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

Inclusion Criteria

* Be at least 18 years of age, male or female, of any race
* Provide written informed consent and sign a HIPAA form
* Willingness and ability to follow all instructions and comply with schedule for follow-up visits
* For females: Must not be pregnant
* Having topographic evidence of keratoconus which is graded as moderate or severe keratoconus.

Exclusion Criteria

* Contraindications, sensitivity or known allergy to the use of the test article(s) or their components
* If female, pregnant
* Eyes classified as either normal, atypical normal, keratoconus suspect or mild keratoconus on the severity grading scheme
* Previous ocular condition (other than refractive error) in the eye to be treated that may predispose the eye for future complications For example: a history of corneal disease (e.g., herpes simplex, herpes zoster keratitis, corneal melt, corneal dystrophy, etc.)
* A history of delayed corneal healing in the eye to be treated
* Have used an investigational drug or device within 30 days of the study
