1

A handheld, automated applanation tonometer has shown accurate intraocular pressure measurements in human donor eyes.
2

The device automates the subjective component of traditional Goldmann applanation tonometry, improving measurement consistency.
3

Testing on eight human cadaveric eyes demonstrated a mean difference of −1.2 mm Hg from set intraocular pressure values.
4

Performance was notably better in the 10–30 mm Hg range, with a mean absolute difference of 1.4±1.1 mm Hg.
5

The study highlights the need for further clinical evaluations to assess usability and performance across diverse corneas.

Perspectives on Medicare’s Proposed iDose TR Coverage Policy

In May 2026, 5 Medicare Administrative Contractors released proposed Local Coverage Determinations (LCDs) addressing Medicare reimbursement for anterior-segment intraocular nonbiodegradable drug-eluting systems, a category that currently includes only the travoprost intracameral implant iDose TR (Glaukos). Glaucoma Physician spoke with several leading surgeons who expressed concerns about the proposed LCDs and suggested changes they believe would better reflect contemporary glaucoma practice.
