Abstract
Purpose :
No previous studies have reported long-term visual outcomes and complication rates of Yamane technique fixation combined with Pars Plana Vitrectomy. This retrospective study aimed to describe the long-term clinical outcomes of the Yamane transconjunctival sutureless intrascleral intraocular lens (SIS IOL) fixation technique combined with pars plana vitrectomy (PPV) in patients with aphakia, IOL dislocation, IOL opacification, and lens luxation.<div class="acfifjfajpekbmhmjppnmmjgmhjkildl" id="acfifjfajpekbmhmjppnmmjgmhjkildl"> </div>
Methods :
A retrospective analysis was conducted at a Private Hospital in Brazil. Demographic data, preoperative and postoperative best-corrected visual acuity (BCVA), indications for surgery, pre-existing ophthalmologic comorbidities, follow-up length, necessity for surgical reintervention, and postoperative complications were recorded.As preoperative and postoperative visual acuity did not follow a normal distribution, the Wilcoxon signed-rank test was used for statistical analysis.<div class="acfifjfajpekbmhmjppnmmjgmhjkildl" id="acfifjfajpekbmhmjppnmmjgmhjkildl"> </div>
Results :
The study enrolled 50 patients with various surgical indications: aphakia (9), IOL dislocation (33), IOL opacification (4), and lens luxation (4). Participants, mean age 68.78 ± 15.02 years (range: 14–96), underwent an average follow-up of 11.08 ± 9.99 months (range: 0.39–36.39). BCVA significantly improved from 0.667 ± 0.486 logMAR to 0.523 ± 0.456 logMAR (p=0.0182). Surgical reintervention was needed in 18%, with 8% within three months. Seventeen complications occurred: corneal edema (20%), vitreous hemorrhage (6%), cystoid macular edema plus vitreous hemorrhage (2%), IOL luxation (4%), and IOL luxation plus vitreous hemorrhage in one patient.<div class="acfifjfajpekbmhmjppnmmjgmhjkildl" id="acfifjfajpekbmhmjppnmmjgmhjkildl"> </div>
Conclusions :
The Yamane SIS IOL fixation technique in conjunction with PPV proved to be an effective and dependable surgical approach for complicated cases necessitating additional interventions, as demonstrated by the long-term follow-up results.<div class="acfifjfajpekbmhmjppnmmjgmhjkildl" id="acfifjfajpekbmhmjppnmmjgmhjkildl"> </div>
