Purpose

To evaluate stability, and identify factors affecting postoperative refractive errors following modified Yamane  sutureless intrascleral fixation technique without trimmed haptics.

Setting

This was a retrospective study conducted at Nihon University Itabashi Hospital.

Methods

All cases of intrascleral fixation surgery performed by two surgeons (Surgeon A and B) from September 2019 to March 2024 were included.
 
Preoperative measurements included three variables: best-corrected visual acuity (BCVA (logMAR)), intraocular  pressure(IOP (mmHg)), and corneal endothelial cell count (cells/mm2). Postoperative measurements included seven variables:refractive error (D), aqueous depth (AQD (mm)), tilt (°), and decentration (mm) in addition to preoperative variables.Changes from pre- to postoperative measurements were assessed using the Wilcoxon signed-rank test, while differences between the two surgeons were assessed using the Wilcoxon rank-sum test.
 

Results

This study included 44 eyes which consisted of 22 cases by Surgeon A, and 22 cases by Surgeon B. (mean age, 66.8 ± 13.7 years) There were no significant differences in pre- and postoperative factors except for the postoperative errors. Postoperative refractive errors were also not significantly different, with Surgeon A at 0.23±0.40 and Surgeon B at 0.22±0.41. The postoperative refractive error was 0.43±0.75D (range: -1.00 to 1.70D) in Surgeon A,whereas -0.18±1.35D (range: -3.50 to 2.20D) in Surgeon B, showing a slight hyperopic tendency for Surgeon A.Univariate analysis of postoperative refractive errors showed a significant positive correlation with postoperative AQD(p <0.05).

Conclusions

The stability of refractive error, and the centration was not inferior to previous studies. The comparison of the two surgeons showed differences in postoperative refractive error tendencies, with postoperative AQD being significant influencing factors.
