iCare vs Tonopen vs Goldmann Applanation Post-vitrectomy Surgery

A Comparative Study of Icare Rebound Tonometry With Other Tonometry Modalities in Patients Following Vitreoretinal Surgery.

The purpose of the study is to compare the measurement of pressure inside the eye using three different FDA-approved devices (Icare, Tonopen, and Goldmann applanation).

The three above devices will be used to measure intraocular pressure in patients one day following vitreoretinal surgery. The underlying reason for surgery is not being considered in this study. The measured pressures will be compared across devices in eyes filled with fluid, gas, and silicone oil.

Inclusion Criteria:

• Duke Eye Center patients 18 years or older
• capacity to give legally effective consent
• scheduled to undergo vitreoretinal surgery

Exclusion Criteria:

• individuals unable to give consent
