Clinical evaluation of the Keeler PULSAIR 2000 tonometer.

Intraocular pressures (IOPs) were obtained from 380 eyes of 190 normal subjects using hand-held Keeler PULSAIR 2000 and slit lamp-mounted Goldmann tonometers. IOPs obtained with the PULSAIR were in close agreement with Goldmann pressures over the range of IOPs represented in the subject population (9-27 mmHg). This agreement is better than that found in a previous study comparing the original PULSAIR model to the Goldmann, and suggests that the model 2000 represents a significant improvement over the original unit.
