In the search for more accurate ways to determine intraocular pressure, the Halberg applanation tonometer may represent an alternative to the Schi0tz tonometer for routine screening pressure measurements. Although between 100 to 150 measurements are generally required to gain proficiency with the Halberg, the instrument is accurate in patients with normal corneas even with very abnormal scleral...
