In order to evaluate the Halberg applanation tonometer, the intraocular pressure of 150 normal eyes was measured by a first year resident in ophthalmology using both it and the Perkins hand applanation tonometers. After sufficient experience, reliable readings were obtained with either instrument. While the Perkins can be easily used by someone trained in use of the Goldmann applanation tonometer, the Halberg tonometer was easier to learn to use and should be considered for use by medical students and ophthalmic technicians. Furthermore, because of the similarity of its operation, an easy transition can be made from Schiøtz to Halberg tonometry.
