New nomogram may sharpen vision in keratoconus patients
NCT ID NCT07540208
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a new surgical guide (the Alfonso nomogram) helps doctors place corneal ring implants more effectively in people with moderate keratoconus. Twenty-five adults aged 18–35 with progressive disease received the implant. Researchers will measure changes in vision, glasses prescription, and corneal shape.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Intrastromal corneal ring segment (Keraring) implantation
What this could lead to
If successful, this could provide a more reliable way to flatten the cornea and improve vision in people with moderate keratoconus.
What could go wrong
This is a small, early-stage study with only 25 participants, so results may not apply to everyone. The procedure carries risks like infection or implant displacement.
