Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
