23 Gauge and 20 Gauge Vitrectomy for Rhegmatogenous Retinal Detachments

A Prospective, Randomized Study Comparing 23-gauge and 20-gauge Pars Plana Vitrectomy for Repair of Pseudophakic Rhegmatogenous Retinal Detachments

This study is a comparison (23 gauge vs 20 gauge instrumentation) of surgical instrumentation for retinal detachment repair.

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.

Inclusion Criteria:

• Ability to provide written consent and comply with study assessments for the full duration of the study.
• Presence of retinal detachment with history of cataract surgery.
• Vision of hand motion or better.

Exclusion Criteria:

• Presence of a very large tear or type of retinal detachment usually a result of trauma.
• Prior eye surgery except for cataract surgery.
• Presence of significant scar tissue.
• Presence of retinal detachment due to hole in the macula.
