Measuring eye pressure and fluid outflow during cataract or glaucoma surgery

Dynamic Ocular Tonometry Study During Intraocular Surgery

Observational The New York Eye & Ear Infirmary · NCT07425496

This will test whether measuring eye pressure and fluid outflow during cataract or glaucoma surgery with a disposable sensor can help predict and improve recovery for adults having these operations.

What this trial studies

This prospective, single-arm observational study will use a sterile, single-use Deltran I pressure sensor to record intraoperative intraocular pressure and calculate outflow capacity in adults undergoing cataract and/or glaucoma surgery at the New York Eye and Ear Infirmary of Mount Sinai. Investigators will collect intraoperative tonographic biometry and follow postoperative intraocular pressure and clinical outcomes for up to 90 days. The goal is to correlate intraoperative pressure and outflow measurements with short-term surgical success and complications. Participants are recruited from surgeons affiliated with the Mount Sinai Health System and will receive standard surgical care with added intraoperative monitoring.

Who should consider this trial

Good fit: Adults (18 and older) undergoing cataract and/or glaucoma surgery at the Mount Sinai Health System who can provide informed consent are ideal candidates.

Not a fit: People under 18, pregnant women, those lacking decision-making capacity, prisoners, and patients treated outside Mount Sinai are excluded and would not receive direct benefit from participation.

Why it matters

Potential benefit: If successful, intraoperative pressure measurements could help surgeons predict which patients will achieve better IOP control and tailor postoperative management to reduce complications.

How similar studies have performed: Measuring ocular outflow and IOP has been studied before, but using an intraoperative disposable tonographic sensor to predict postoperative outcomes is relatively novel with limited published outcome data.
