Long term outcomes of Yamane technique in various indications

Abstract

Introduction: To describe the clinical and refractive outcomes of Yamane transconjunctival sutureless intrascleral intraocular lens (SIS IOL) fixation technique in aphakic and dislocated IOLs. Methods: The aphakic and IOL dispositioned patients who underwent Yamane surgery in Bozyaka Research and Training Hospital were evaluated retrospectively. The demographic data, preoperative & postoperative best-corrected visual acuity (BCVA), spherical equivalent (SE), indication for surgery, additional surgical interventions, complications, the final status of retina, and central macular thickness (CMT) through spectral-domain optic coherence tomography (SD-OCT) were recorded. Results: A total of 30 eyes of 30 patients were evaluated. The indication for surgery was aphakia in 24 patients, lens dislocation in 1 patient, and IOL dislocation in 5 patients. The mean age of participants was 64.17 ± 14.69 years, and the mean follow-up was 46.07 ± 7.96 months. The mean BCVA was improved from 0.25 ± 0.22 (−0.94 ± 0.83 log MAR) to 0.49 ± 0.24 in decimals (−0.37 ± 0.27 log MAR) (p:0.041). The mean subjective refraction improved from 10.06 ± 3.10 to −1.45 ± 0.73 D in the final visit (p < 0.05). The mean of cylindrical refraction was −1.22 ± 1.03 D in the postoperative period. At the time surgery, 36.6% of patients required at least one additional surgical procedure. During follow-up period, two (6.7%) out of 30 of patients had retinal detachment, two of the patients (6.7%) occured epiretinal membrane, one of the patients (3.3%) had cystoid macular edema. Conclusion: Yamane SIS IOL fixation technique is an effective and reliable surgical option in complicated cases that require additional surgical interventions in long-term follow-up.
