To compare the outcomes of transscleral four-point fixation using a closed continuous-loop suture and transconjunctival intrascleral haptic fixation (Yamane technique) for intraocular lens (IOL) fixation.
Methods:
Patients who underwent scleral fixation of IOL using four-point fixation with a closed continuous-loop suture and the Yamane technique were reviewed. Demographics, pre- and postoperative data, including operation time, complications, and reoperation rates, were reviewed. The cumulative probability of remaining free from IOL redislocation was analyzed using Kaplan–Meier curves, and the factors associated with IOL redislocation were assessed using a Cox proportional hazards model.
Results:
A total of 179 eyes of 175 patients were included, comprising 120 eyes in the four-point fixation group and 59 eyes in the Yamane group. Visual and refractive outcomes were comparable 6 months postoperatively. Operative time was significantly shorter in the Yamane group (35.6 ± 10.9 vs. 49.5 ± 14.7 min;
Conclusion:
Both four-point fixation and the Yamane technique yielded comparable visual outcomes and safety profiles. The Yamane technique offered shorter operative time, whereas the four-point fixation was associated with a lower risk of IOL redislocation. These findings highlight the importance of preoperative structural assessments in guiding the selection of fixation methods.
