About this trial
The study will pertain to investigating the impact of high vs low IOP on the intraoperative experience and comfort for the patient and surgeon. Our hypothesis is that operating at a more physiological IOP using Unity VCS/CS and Centurion with Active Sentry at a higher, or more traditional IOP will result in significantly less discomfort/pain as assessed by the decreased need for rescue medication and lower VAS scores.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Visually significant cataract 2-3+ undergoing uncomplicated cataract surgery with similar cataract grade in both eyes
Unremarkable ocular health but inclusive of early AMD
Disqualifiers
H/o ocular surgery including corneal refractive surgery

Uncontrolled diabetes and diabetic retinopathy
Small pupils
Trial design
Parallel
Treatments tested in this trial
High IOP Setting
DeviceProspective, single-surgeon, eyes undergoing phacoemulsification will be randomized to low (IOP 25mmHg) or high (IOP 65mmHg) IOP, contralateral eye will receive other treatment
Low IOP Setting
DeviceProspective, single-surgeon, eyes undergoing phacoemulsification will be randomized to low (IOP 25mmHg) or high (IOP 65mmHg) IOP, contralateral eye will receive other treatment
Treatment groups
Trial outcomes
Primary outcomes
Rescue Medication
Percent of pts in each group requiring rescue medication for breakthrough discomfort/pain
Secondary outcomes
VAS Pain Score
Discomfort/pain score at phaco, I/A, visco removal. VAS score : 0 - no pain, 10 - unbearable pain
Surgeon Intraoperative Experience
1- Poor: fluctuating chamber (reverse pupillary block or surge) and reduced efficiency (nucleus \& cortex removal) * 2- Good: \>75% chamber stability and adequate efficiency * 3- Excellent: Minimal to no fluctuating chamber and excellent efficiency
Cost Analysis
Cost-analysis on intraoperative medications utilized in high vs low IOP groups
Breakthrough pain and discomfort High Axial Length
VAS Pain score on subjects with axial length of \>24.5mm VAS score : 0 - no pain, 10 - unbearable pain If patients experienced breakthrough pain during surgery, additional topical anesthetic, intracameral lidocaine, and/or opioid will be used per surgeon discretion and stage of surgery recorded.
