Brief summary
This study is a comparison (23 gauge vs 20 gauge instrumentation) of surgical instrumentation for retinal detachment repair.
Detailed description
The majority of studies on PPV for PRD up to this time have used 20-gauge instrumentation. Currently, both 23-gauge and 20-gauge instrumentation are commercially available for PPV. No studies have reported the efficacy of 23-gauge PPV compared to 20-gauge PPV for primary pseudophakic RRD. As a result, many retinal surgeons choose the modality based on personal preference.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Assess the initial retinal reattachment rates by comparing the percentages/amount. | 1 Year |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in best-corrected visual acuity by comparing letters read. | 6 months | To determine the change in best-corrected visual acuity (BCVA) at the pre-operative visit compared to the 6 month post-operative visit |
| Reattachment rates with 23 gauge and 20 gauge PPV by comparing the amount. | 1 year | To determine the final retinal reattachment rates with 23-gauge and 20-gauge PPV if multiple surgeries are required. |
| Operating time for 23 gauge versus 20 gauge PPV (time measurement) | 1 day- Day of surgery | This will be done to determine operating times for 23-gauge versus 20-gauge PPV for primary repair of PRD. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Compare rates of intraoperative and postoperative complications by comparing the amount and severity of these complications. | 1 year | To describe and compare rates of intraoperative and postoperative complications with 23-gauge versus 20-gauge PPV for primary repair of PRD, including but not limited to post-operative hypotony, choroidal detachment, proliferative vitreoretinopathy, and endophthalmitis. |
