Efficacy and Safety of Tran Cannula in Combined Pseudoexfoliative Glaucoma and Cataract Surgery Compared With Augmented Ocular Irrigation
Pseudoexfoliative glaucoma is a glaucoma secondary to pseudoexfoliative syndrome; cataract surgery is often more difficult, with more complications. Tran's cannula is a single-use irrigation system designed for cleaning, with the pseudoexfoliative material remaining in the trabecular meshwork. The main objective of this study is to evaluate the efficacy of the Tran cannula, in comparison with increased irrigation, in lowering intraocular pressure (IOP) in patients with pseudoexfoliative glaucoma and treated for glaucoma, and with an indication for isolated cataract surgery.
• Patients with cataract and early-to-moderate pseudoexfoliative glaucoma (GPX) scheduled for isolated cataract surgery.
• Reliable visual field, Humphrey 24-2, Sita-Fast, with typical glaucoma alterations, and with mean deviation ≤-12 dB.
• OCT with ganglion cell alterations and fibers typical of glaucoma.
• Typical glaucomatous neuropathy
• Slit-lamp signs of pseudoexfoliation.
• Open angle (2 to 4, according to Shaffer classification) determined by gonioscopy.
• Untreated eye pressure \>21 mmHg and \<33 mmHg
