Brief Summary
We aimed o compare the refractive changes associated with pars plana vitrectomy with or without intraocular gas tamponade in pseudophakic eyes. This retrospective study included pseudophakic patients with Nd:YAG laser posterior capsulotomy who underwent 23G PPV between February 2015 and March 2019. Group 1 consisted of patients with regmatogenous RD who underwent PPV and 12% perflouropropane (C3F8) gas tamponade whereas Group 2 consisted of patients who underwent PPV for epiretinal membrane or vitreous hemorrhage (VH). No tamponade was used in Group 2. Minimum follow-up was 12 months.

12 months
Study Arms (1)
Group
27 patients, Group 1 consisted of patients with pseudophakic rhegmatogoneous retinal detachment who underwent pars plana vitrectomy and 12% perflouropropane (C3F8) gas tamponade and 20 patients Group 2 consisted of patients with epiretinal membrane or vitreous hemorrhage who underwent PPV without any tamponade
Interventions
23 gauge pars plana vitrectomy was performed for retinal detachment, vitreous hemorrhage or epiretinal membrane
Eligibility Criteria
Pseudophakic patients treated with neodymium:yttrium-aluminum-garnet Nd: YAG laser and subsequently underwent 23 gauge pars plana vitrectomy for vitreous hemorrhage, epiretinal membrane, or rhegmatogenous retinal detachment.
You may qualify if:
- Patients aged ≥ 18 years
- Pseudophakic patients who underwent pars plana vitrectomy
You may not qualify if:
- Patients aged 18 years \>
- Patients with a spherical refractive error \> ±6 D
