Comparing two glaucoma implants and their eye surface effects

This trial is testing whether a newer glaucoma drainage device called the Paul implant causes less damage to the cornea (the clear front part of your eye) than an older device called the Baerveldt implant. Both devices are surgical implants designed to lower eye pressure and slow glaucoma progression. The study will follow patients for two years to compare how well each implant works and how it affects the health of corneal cells.

While the Baerveldt implant successfully lowers eye pressure, doctors have noticed it can sometimes damage the delicate cells lining the front of the eye over time. The Paul implant has a thinner tube design that may sit farther away from these cells, potentially causing less harm.
