Final answer:
Instruments used during removal of foreign bodies from the eye and performance of comprehensive eye examinations include tonometers, which measure intraocular pressure.
Step-by-step explanation:
The instruments used during removal of foreign bodies from the eye and performance of comprehensive eye examinations include tonometers. Tonometers are used to measure intraocular pressure, which is the pressure within the eye.
One type of tonometer is a noncontact tonometer that uses a puff of air to measure the force needed to indent the eye. If the intraocular pressure is high, the eye will deform less and rebound more vigorously.
Regular measurements of intraocular pressure are important, especially for individuals over 40 years of age who are at a greater risk of developing glaucoma.
