When we picture sight being restored, we imagine the big moment: a bandage lifted, a face coming into focus. What we don’t picture is the “Air Puff” machine quietly doing its job without protest. In eye care, that’s its own kind of miracle.

Modern ophthalmology depends on a fleet of highly specialized devices, each with occasional quirks. Keeping them in line is the work of the Biomedical Engineering Department, whose goal is wonderfully uncompromising: zero downtime.

At the Workshop on Ophthalmic Maintenance Services at Tilganga Institute of Ophthalmology, this behind-the-scenes world takes center stage. Here, maintenance is part science, part detective work, and part coordination with vendors who don’t always share your sense of urgency.

Why does it matter? Because when a machine fails, a patient, often someone who has traveled for days, may not get the care they came for.

With your support, Seva Nepal has launched a National Community of Practice for sustainable eye care, helping partners share solutions, strengthen vendor relationships, and tackle common maintenance gaps.

The payoff: Tilganga reports 99.89% uptime across 165 devices. Which is another way of saying that the machines are behaving and that patients are being seen.
