简要总结
To determine if the Barraquer tonometer provides an accurate and reliable measurement of intraocular pressure. The Barraquer tonometer is a device used to safely and painlessly measure intraocular pressure.
详细描述
Intraocular pressure will be checked using four different methods of tonometry. These four methods will include Tonopen, Goldmann applanation tonometry, Schiotz tonometry, and Barraquer tonometer. The data will then be compared to determine the reliability and accuracy of the Barraquer tonometer.
