Concordance between the new modular slit-lamp mounted Goldmann applanation tonometer (GAT), conventional slit-lamp mounted GAT, and Perkins tonometer.

ABSTRACT:

Purpose

To evaluate a new device, the Goldmann applanation tonometer (GAT) mounted on a novel handheld 3D-printed modular slit lamp (MSL), and compare it with the gold standard slit-lamp-mounted GAT and the handheld Perkins tonometer.

Methods

One hundred eyes from 100 participants were included in this cross-sectional observational study. The MSL mount was customized for the selected tonometer (Model AT030, Carl Zeiss, India). A Samsung Galaxy S2 mobile phone was used for observing mires and photography during tonometry. One observer measured intraocular pressure (IOP) with slit-lamp GAT, and another observer measured with MSL GAT and Perkins tonometers. The tonometry sequence was slit-lamp GAT, MSL GAT, and Perkins tonometer, with a 5-minute interval between readings.
