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.

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.

Inclusion Criteria:

• Individuals undergoing cataract and/or glaucoma surgery in the Mount Sinai Health System.

Exclusion Criteria:

• Individuals less than 18 years old, pregnant women, those without capacity to make their own decisions, and prisoners.

Patients will be stratified according to disease entity (glaucoma and/or cataract), severity (mild, moderate, etc), and surgery performed (cataract surgery, cataract surgery combined with glaucoma surgery, trabeculectomy, and/or glaucoma device implantation).

Undecided at this time.
