To Study Ocular Outflow Dynamics of the Eye Using Intraoperative Tonographic Biometry and Assess Its Predictive Value in Improving Postoperative Outcomes.

February 20, 2026 updated by: The New York Eye & Ear Infirmary

Dynamic Ocular Tonometry Study During Intraocular Surgery

The objective of this study is to evaluate ocular outflow dynamics of the eye using intraoperative tonographic biometry and assess its predictive value in improving postoperative outcomes.

Detailed Description

This study proposes to measure the intraocular pressure (IOP), ocular fluid dynamics and outflow homeostasis in patients undergoing intraocular surgery to understand how post-operative surgical success can be optimized and complications prevented.

This is a prospective observational study, single study arm and at a single-site. Recruitment will be from physicians affiliated with the Mount Sinai Health System who are performing intraocular surgeries, such as cataract and/or glaucoma surgeries. Intraocular pressure measurements will be taken using an FDA-registered, sterile, single-use, disposable Deltran I pressure sensor designed for measuring physiological pressures of the body to obtain concomitant intraocular measurement and outflow capacity calculation during the surgery. Monitoring intra ocular pressure postoperatively for up to 90 days.
