Abstract:AIM: To discuss the efficacy of sutureless intrascleral intraocular lens(IOL)fixation with the modified Yamane technique in patients with incomplete lens capsule.
METHODS: Retrospective study. Patients with incomplete lens capsular bags who were treated in our hospital from January 2022 to December 2024 were selected. According to the treatment plan, the patients were divided into a modified group, who were treated with the modified Yamane method for sutureless IOL fixation between the sclera layers. The traditional group was treated with the traditional ciliary sulcus suture suspension surgery. Postoperative follow-up was conducted for 6 mo. The operation time, best corrected visual acuity(BCVA), visual quality score, intraocular pressure, IOL position and complications were compared between the two groups of patients.
RESULTS: A total of 84 patients(84 eyes)were included in this study. Among them, 42 patients(42 eyes)were in the modified group, and 42 patients(42 eyes)were in the traditional group. There was no difference in the general preoperative data between the two groups(all P>0.05). The surgical time of the modified group was(26.97±6.58 min), which was shorter than the traditional group's(33.42±7.64 min; P<0.01). At 1, 3, and 6 mo after surgery, the modified group showed better visual quality score and BCVA than the traditional group(all P<0.05). At 6 mo after surgery, the intraocular pressure and the vertical deviation of the IOL in the modified group were both lower than those in the traditional group(all P<0.05). During the follow-up period, the complication rate in the traditional group was 19%, while that in the modified group was 7%. There was no statistically significant difference in postoperative complications between the two groups(χ2=1.816, P>0.05).
CONCLUSION:For patients with incomplete lens capsule, the modified Yamane method of sutureless intrascleral fixation of IOL is effective in treating this condition. It can improve vision, shorten the operation time, reduce the occurrence of complications, and ensure better vertical position stability of the IOL.
