ClinConnect Summary

The INTACS trial is studying a surgical treatment called INTACS, which involves placing special ring segments in the eye to help improve vision for people with a condition called keratoconus. This condition causes the cornea, the clear front part of the eye, to become thin and misshapen, leading to blurry vision that cannot be corrected with glasses or contact lenses. The trial aims to see how well these ring segments work in reducing vision problems like myopia (nearsightedness) and astigmatism in patients who have experienced worsening vision and have few options left.

To participate in this trial, you must be at least 21 years old and have noticed a steady decline in your vision to the point where glasses or contact lenses no longer help. You also need to have clear central corneas and enough thickness in your corneas for the surgery. If you qualify, you can expect to undergo a surgical procedure to implant the INTACS segments, which may help improve your vision. It’s important to note that this trial is not yet recruiting participants, so you will need to wait for it to start before applying.
