Comparison of the Yamane technique with and without simultaneous pars plana vitrectomy: Safety and efficacy analysis

To compare patients who underwent scleral fixation using the Yamane technique with and without simultaneous pars plana vitrectomy.

A total of 37 patients were included in the study. Eighteen underwent simultaneous pars plana vitrectomy. The Yamane technique alone was performed only in patients with aphakia who had previously undergone pars plana vitrectomy for various reasons. Final lens position, best corrected visual acuity spherical equivalent, complication rates, and optical coherence tomography findings were recorded.

The duration of aphakia before intraocular lens implantation ranged from 1 month to 21 yr. Postoperative best corrected visual acuity improved in both groups, with no statistically significant difference (with pars plana vitrectomy: 0.42 ± 0.34; without pars plana vitrectomy: 0.32 ± 0.26; p=0.33). The spherical equivalent was also not significantly different between groups (with pars plana vitrectomy: 0.29 ± 1.08; without pars plana vitrectomy: 0.65 ± 2.23; p=0.53). There were no significant differences between the groups in complication rates, postoperative intraocular lens position or optical coherence tomography findings.

There was no difference in terms of safety or efficacy between the two approaches. Surgical decisions may be based on the surgeon's experience and the patient's systemic and ocular condition.
