"SYRI" - A hands-on teaching model for SYRInging of nasolacrimal duct.

Summary: Before performing eye surgery, doctors must check if a patient's tear ducts are blocked. Traditionally, trainees learn this "syringing" technique on real patients, which can be risky and uncomfortable. To solve this, researchers created "SYRI," a clever "Do-It-Yourself" model made from simple ink droppers and silicone tubing. This inexpensive tool mimics the human tear drainage system, allowing students to practice flushing fluids and identifying blockages safely. While it doesn't have eyelids (so you can't practice stretching them), it is an excellent, low-cost way for beginners to build skill and confidence before treating actual people.
