Purpose: To report results of a modified Yamane technique for scleral fixation of the intraocular lens (IOL). Methods: Data from all patients treated with scleral fixation using the Avansee AN6A at our hospital by a single surgeon were obtained and retrospectively analyzed from our database. In our technique, the trailing haptic was externally inserted into the lumen of the 30G needle. The preoperative measurements included three variables: best-corrected visual acuity (BCVA,Snellen), intraocular pressure (mmHg), and corneal endothelial cell count (cells/mm 2 ). Postoperative measurements included: refractive error (D), aqueous depth (mm), tilt (°), decentration (mm), and the three preoperative variables. Results: This study included 20 eyes (mean age, 65.3±13.5 years). Preoperative conditions included lens subluxation (4 eyes), IOL dislocation (13 eyes), and aphakia (3 eyes). The BCVA improved from 20/32 preoperatively to20/20 postoperatively. The mean preoperative corneal endothelial cell density was 2,282 cells/mm 2 and changed to 2,091 cells/mm 2 at the last visit. Postoperative refractive error was slightly myopic (-0.13±1.4 D). Regarding the position of fixated IOLs, postoperative tilt was 5.57 ± 3.35°. and postoperative decentration was 0.50 ± 0.26 mm. Conclusion: The simplified Yamane technique showed good overall clinical outcomes and stability of refractive predictability when performed by a single surgeon, making it easier to master. Further studies are required to expand on this simplified procedure.
