BACKGROUND: In intraocular lens (IOL) sutureless intrascleral fixation using the Yamane technique, untrimmed haptics may be overlong in some cases due to varied haptic lengths and individual differences. However, whether trimming the haptic affects IOL stability remains unknown.
MATERIAL AND METHODS: Thirty-nine eyes of 39 patients who underwent Yamane sutureless intrascleral fixation surgery between October 2017 and February 2018 were analyzed retrospectively. Nineteen patients underwent surgery with untrimmed haptics and 20 patients with trimmed haptics. The slit-lamp examination, best-corrected visual acuity (BCVA), corneal endothelial cell density (ECD), IOL position, and complications were assessed.
RESULTS: The mean follow-up periods in the untrimmed and trimmed groups were 27.84±2.89 months and 27.85±2.41 months, respectively. The BCVA improved and ECD decreased in both groups postoperatively (all P<0.01). No significant differences were seen between the 2 groups in postoperative BCVA, postoperative ECD, IOL tilt at 3 months and 24 months, and IOL decentration at 3 months (all P>0.05). There were significant differences between the 2 groups in IOL decentration at 24 months (P<0.05). Compared with postoperative 3 months, both the postoperative IOL tilt and decentration at 24 months increased in the 2 groups (all P<0.01). Postoperative complications included IOL elevation (11% in the untrimmed group and 10% in the trimmed group), as well as haptic extrusion (16% in the untrimmed group).
CONCLUSIONS: The position of the IOL may change with time, but trimming the haptic to an optimum length tends to provide greater IOL stability.
