Tips to addressing cataract surgery challenges in glaucomatous eyes
Use of various temporary and permanent devices for successful outcomes highlighted
Patients needing glaucoma surgery may also be candidates for a combined procedure with cataract removal and IOL implantation. For a variety of reasons, however, cataract surgery may be challenging in eyes with glaucoma.
Alan S. Crandall, MD, provided a sampling of cases to demonstrate the complexities encountered when performing cataract surgery in glaucoma patients and strategies for achieving successful outcomes.
“Considering the number of combination cases we perform, I have always felt that glaucoma surgeons should also be the best cataract surgeons,” said Dr. Crandall, professor and senior vice chairman of ophthalmology and visual sciences, and director of glaucoma and cataract at the John A. Moran Eye Center, University of Utah, Salt Lake City.
Videos from cases with pseudoexfoliation and traumatic glaucoma highlighted the potential for encountering eyes with weak, loose, and missing zonules. In eyes with traumatic glaucoma, Dr. Crandall cautioned that the extent of the zonular dialysis is probably much greater than what is initially perceived.
“In eyes with trauma, the area of zonular dialysis is probably doubled or tripled,” Dr. Crandall said. “If you see 100 degrees of dialysis, you can expect at least 2 clock hours of additional involvement on the other side.”

The search for glaucoma biomarkers is in high gear. Funded by Catalyst for a Cure, the research program has already produced new biomarker candidates and novel techniques that promise to advance research in glaucoma. Research is focusing on ways to diagnose glaucoma early and detect the specific, minute changes that could allow researchers to reduce vision loss.
Intraocular pressure (IOP) monitoring is based on fiction. Clinicians typically measure IOP over a single visit and extrapolate the value to the patient’s overall condition and the degree of control over their IOP. “New Horizons in IOP Monitoring and Digital Health” session showcased six companies trying to turn the IOP challenge into commercial success.
