Purpose

To report results of a modified Yamane technique for scleral fixation of the intraocular lens (IOL).

Setting

A single-center in Itabashi, Tokyo, Japan.

Retrospective study conducted using data from January 2023 to May 2024.

Methods

Data from all patients treated for aphakia, a dislocated IOL, or a subluxated crystalline lens with scleral fixation using the Avansee AN6A at our hospital by a single surgeon were obtained from our prospective database. In our technique, the trailing haptic was externally inserted into the lumen of the 30G needle. Pre- and postoperative measurements were recorded. The preoperative measurements included three variables: best-corrected visual acuity (BCVA, logMAR), intraocular pressure (mmHg), and corneal endothelial cell count (cells/mm2). 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 significantly improved from 0.19±0.42 logMAR preoperatively to -0.02±0.10 logMAR postoperatively (p=0.011). The mean preoperative corneal endothelial cell density was 2,282 cells/mm2 and the mean postoperative corneal endothelial cell density was 2,091 cells/mm2 at the last visit. Postoperative refractive error was slightly myopic (-0.13±1.4 D).

Conclusions

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 simple and easy procedure.
