Objective To compare the clinical effects between sutureless bridge intrascleral fixation and ciliary sul-cus suture suspension of intraocular lens(IOL)1 year postoperatively.Methods In this retrospective study,14 patients(14 eyes)who underwent sutureless bridge intrascleral IOL fixation in the No.988 Hospital of Joint Logistic Support Force of PLA from March 2019 to January 2022 were taken as the intrascleral fixation group and 15 patients(15 eyes)who under-went IOL ciliary sulcus suture suspension in the same period were taken as the suture suspension group.During the 1-year follow-up,the preoperative and postoperative uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA)(logMAR),spherical equivalent(SE),endothelial cell count(ECC),intraocular pressure(IOP)and IOL position were compared between the two groups.Results At 1,6 and 12 months postoperatively,the UCVA in both groups significant-ly increased compared with those before surgery(all P＜0.05),and UCVA in the intrascleral fixation group were better than those in the suture suspension group at all postoperative time points(F=4.560,6.411 and5.373;all P＜0.05).At 1,6 and 12 months postoperatively,there was no significant difference in BCVA in both groups compared with those before surgery(all P＞0.05),but BCVA in the intrascleral fixation group were better than those in the suture suspension group at all postoperative time points(F=6.170,6.957 and 10.624;all P＜0.05).After surgery,eyes in the intrascleral fixation group showed hyperopia drift,while eyes in the suture suspension group showed myopia drift.At 1,6 and 12 months post-operatively,the SE of the intrascleral fixation group were(0.59±0.30)D,(0.57±0.27)D and(0.64±0.29)D,respec-tively,and those of the suture suspension group were(-0.75±0.44)D,(-0.72±0.42)D and(-1.12±0.64)D,re-spectively.At 6 months postoperatively,the ECC of both groups were significantly lower than those before surgery(t=8.579 and 21.929;both P＜0.001).The IOP in both groups were within the normal range preoperatively and stable during the follow-up.The IOL were centrally located without obvious decentration or tilt during the follow-up.In addition,there were no vitreous and retinal complications.Conclusion Both sutureless bridge intrascleral IOL fixation and IOL ciliary sulcus suture suspension can obtain a favorable prognosis of visual acuity with refractive shift,while sutureless bridge in-trascleral fixation shows better clinical outcomes.
