Abstract:
AIM: To compare the application of two distinct suspension suture fixation techniques in intraocular lens implantation.METHODS: Retrospective study. A total of 60 patients(60 eyes)who underwent intraocular lens suspension surgery at ophthalmology department of our hospital between January 1, 2021, and December 1, 2023 were included. Patients were divided into two groups based on the suturing techniques: the control group(n=30)received sub-scleral flap suture fixation, while the intervention group(n=30)underwent Z-shaped suture fixation. A 6 mo postoperative follow-up was conducted to assess surgical duration, visual acuity and quality, ocular structure, clinical efficacy, postoperative expose rate of sutures, diopters and decentration of intraocular lens.RESULTS:The mean operative time was significantly longer in the intervention group(50.5±3.1 min)compared to the control group(40.9±2.8 min; P<0.01). At 6 mo postoperatively, both groups demonstrated significant improvements in uncorrected and best-corrected visual acuity compared to preoperative values(both P<0.01), and there were no statistically significant differences in the uncorrected and best corrected visual acuity between the two groups(all P>0.05); at 6 mo postoperatively, the visual quality of the intervention group was better than that of the control group(P<0.05). While both groups exhibited a significant reduction in corneal endothelial cell count postoperatively(both P<0.01), there was no significant difference between the groups(P>0.05). The overall efficacy rate and suture exposure rate were comparable between the groups at 6 mo postoperatively(P=0.542 and P>0.05, respectively). However, significant differences were observed in postoperative diopters and intraocular lens decentration between the two groups(both P<0.01).CONCLUSION:Although both suture fixation techniques yielded satisfactory clinical outcomes in intraocular lens implantation, the Z-shaped suture fixation demonstrated superior performance in terms of visual quality and preservation of ocular structural integrity.
