Keeler Applanation Tonometer

This used Keeler Applanation Tonometer is a slit lamp mounted instrument designed to measure intraocular pressure using the classic applanation method, in which a small flattened area of the cornea is measured under controlled force. Applanation remains a gold standard technique for IOP assessment because of its high accuracy and long clinical track record, and this Keeler unit is built to mount directly onto compatible slit lamp biomicroscopes for stable, repeatable readings. The design allows the examiner to view the fluorescein pattern directly through the slit lamp optics while adjusting pressure via a calibrated dial. In daily practice, this tonometer supports comprehensive eye exams, glaucoma diagnosis and monitoring, and pre-surgical clearance where precise pressure values are required. Because it integrates with existing slit lamp hardware, it fits naturally into established exam room workflows without adding a separate freestanding device. Clinicians rely on this style of tonometer when a definitive, well validated pressure reading is needed rather than a quick screening estimate. This particular tonometer is previously owned and has been inspected for proper mechanical operation, including smooth dial movement and secure slit lamp mounting. It offers a dependable, budget friendly way for an eye care practice to add or replace applanation tonometry capability using a trusted Keeler design.
