To investigate the impact of high vs low Intraocular Pressure (IOP) on the intraoperative experience for the patient and surgeon. Operating at a more physiologic IOP using Active Sentry hand piece during cataract surgery will result in significantly less discomfort/pain as assessed by the decreased need for rescue medication

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Medication Rescue | Percentage (%) of pts in each group requiring treatment for breakthrough discomfort/pain | Intraoperative | |
Secondary | Physiologic Responses associated with pain/inflammation: | Blood pressure- measured systolic pressure over the diastolic pressure | Intraoperative | |
Secondary | Physiologic Responses associated with pain/inflammation: | Pulse rate- measured in beats per minute (bpm) | Intraoperative | |
Secondary | Surgeon Experience: Assessment on patient cooperation | Surgeon assessment on patient cooperation: poor, good, excellent
Poor cooperation: could not follow instructions, lid squeezing, patient had frequent eye & head movements Good cooperation: able to follow directions 50% of the time, some lid squeezing and patient movement Excellent cooperation: able to follow directions >80% of the time with limited lid squeezing and patient movement |
Intraoperative | |
Secondary | Surgeon Experience: Surgeon intraoperative experience | Surgeon assessment on overall experience: poor, good, excellent
Poor: fluctuating chamber (reverse pupillary block or surge) and reduced efficiency (nucleus & cortex removal) Good: >75% chamber stability and adequate efficiency Excellent: Minimal to no fluctuating chamber and excellent efficiency |
Intraoperative | |
Secondary | Cost- analysis | Cost-analysis on intraoperative pharmacological agents utilized between high vs low Intraocular Pressure (IOP) | Intraoperative |
