Comparison of Keratometric Change After Xen Gel Stent Implantation, Trabeculectomy, and Tube Shunts
In Brief
A clinical study evaluating Corneal topography: OPD-Scan and Corneal topography: Pentacam for Glaucoma, Open-Angle and 3 related conditions. Completed, enrolled 50 participants across 1 site.
Detailed Summary
The main goal of this study is to assess the severity of postoperative corneal astigmatism induced by implantation of the XEN Gel Stent compared to that induced by traditional filtering surgery (trabeculectomy and GDDs). Corneal astigmatism can be assessed using corneal topography, a non-invasive tool which provides an accurate estimate of corneal curvature in all meridians. To the best of our knowledge, no study has yet attempted to quantify the amount of astigmatism induced by the XEN Gel Stent.
