Scleral patch graft cpt code6/2/2023 Here, three surgeons with extensive experience using these devices offer their suggestions for minimizing unwanted complications, improving long-term bleb survival and making sure that a second tube-when necessary-is effective. ![]() Their use is increasing, however, at least partly because of improvements in surgical technique and in the devices themselves, as well as new ideas about preventing tube erosion and fibrosis. Tube shunts have their own challenges and complications, of course, which is why most surgeons haven’t simply given up trabeculectomy and switched to using them as their mainstay surgical option. However, a more time-honored alternative-tube shunts-can often provide that greater level of pressure reduction. New alternatives such as minimally invasive glaucoma surgeries have attracted a lot of attention, but don’t appear to be a replacement for trabeculectomy since they don’t lower pressure as dramatically. Most surgeons treating glaucoma have mixed feelings about trabeculectomy, given its high complication and failure rates.
