Abstract
Purpose
To evaluate intraocular lens stability and identify factors affecting postoperative refractive errors following modified Yamane sutureless intrascleral fixation without trimmed haptics.
Major Findings
Forty-four eyes were included: 22 each from Surgeons A and B cases (mean patient age, 66.8 ± 13.7 years). Postoperative best-corrected visual acuity (BCVA; logarithm of the minimum angle of resolution [logMAR]) was also not significantly different: 0.23 ± 0.40 logMAR and 0.22 ± 0.41 logMAR for Surgeons A and B, respectively. Regarding the position of fixated IOLs, postoperative tilt was 6.33 ± 3.8° for Surgeon A, and 5.51 ± 3.17° for Surgeon B. Postoperative decentration was 0.46 ± 0.22 mm for Surgeon A, and 0.49 ± 0.24 mm for Surgeon B. Postoperative refractive error was 0.43 ± 0.75 D (range: −1.00–1.70 D) for Surgeon A and −0.18 ± 1.35 D (range: −3.50–2.20 D) for Surgeon B, showing a slight hyperopic tendency for Surgeon A. Postoperative refractive errors showed a significant positive correlation with postoperative aqueous depth (P = 0.016).
Conclusions
Refractive error stability and centration were not inferior to those reported in previous studies. Differences in postoperative refractive error tendencies were observed between the two surgeons, with postoperative aqueous depth being a significant influencing factor.
