Study Summary

This trial is for a device that corrects nearsightedness and keratoconus. The device is made of two clear segments from a biomedical material called polymethylmethacrylate, and is available in three thicknesses. Two INTACS inserts may be implanted depending on the orientation of the cone and the amount of myopia and astigmatism to be reduced.

Who is the study for?
This trial is for adults over 21 with keratoconus, a condition that distorts the cornea. It's for those whose vision isn't helped enough by glasses or contacts and who have thick enough corneas (450 microns or more) at the incision site. People with very thin corneas, autoimmune diseases, pregnancy, certain eye conditions, or taking specific medications can't join.Check my eligibility
What is being tested?
The trial tests INTACS prescription inserts made of PMMA material to treat keratoconus. These clear segments are implanted into the eye in varying thicknesses based on individual needs to improve vision without needing a full corneal transplant.See study design
What are the potential side effects?
Potential side effects may include visual disturbances like glare and halos, discomfort or foreign body sensation in the eye, infection risk at the insertion site, and potential need for removal if complications arise.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Astigmatism
Efficacy of INTACS prescription inserts to reduce astigmatism due to Keratoconus as determined by visual acuity examination.
Efficacy of INTACS prescription inserts to reduce other corneal aberrations due to Keratoconus as determined by corneal topography assessment.

Experimental Treatment
Group I: Intacs DeviceExperimental Treatment1 Intervention
INTACS® prescription inserts are an ophthalmic medical device designed for the reduction or elimination of myopia and astigmatism in patients with keratoconus so that their functional vision may be restored and the need for a corneal transplant procedure can potentially be deferred.

Dr. Verity was my Miracle Worker. I was functionally blind before my cataract surgery, but now everything is so colorful and beautiful. I'm grateful to God for him.
