This video outlines pre-operative care and patient preparation for a glaucoma drainage tube procedure, addressing issues like ocular surface health and the management of anticoagulant medications. It then details the consent process, emphasizing clear communication about the diagnosis, the surgery's purpose in lowering intraocular pressure without restoring lost vision, and describing the mechanics of the implant. The document thoroughly explains the benefits of the surgery, primarily focusing on pressure reduction and slowing vision loss, alongside various ways to post-operatively manage eye pressure. Crucially, it enumerates both early and late potential risks and complications associated with the procedure, ranging from bleeding and infection to scarring and potential failure of the implant. Finally, it covers essential post-operative instructions and expectations, including follow-up visit frequency, symptom management, activity restrictions, and the timeline for visual recovery.
