ABSTRACT
AIM:
To compare the efficacy of 25-gauge(25G)vitrectomy combined with intraocular lens transciliary sulcus scleral suture fixation and sutureless scleral tunnel interlamellar fixation in the treatment of complete lens dislocation.METHODS:
Retrospective case-control study. A total of 40 patients(40 eyes)diagnosed with complete lens luxation in the vitreous cavity in our hospital from May 2015 to September 2021 were selected, among which 21 eyes(suture group)underwent 25G vitrectomy combined with intraocular lens fixation via ciliary sulci scleral suture, and 19 eyes(sutureless group)underwent 25G vitrectomy combined with interlamellar scleral tunnel fixation of intraocular lens. The patients in both groups were followed up until 3mo after surgery to observe the operative time, best corrected visual acuity(BCVA), corneal endothelial cell count(CECC), central corneal thickness(CCT)and postoperative complications.RESULTS:
The operation time was significantly shorter in the sutureless group than in the suture group(31.79±6.01min vs. 45.38±8.04min, P<0.001). BCVA in both groups was significantly improved after surgery(all P<0.05), and the BCVA(LogMAR)at 1wk after operation in the sutureless group was significantly better than that in the suture group(0.32±0.14 vs. 0.57±0.25, P<0.001). At 3mo after surgery, CECC in both groups was lower than that before surgery(all P<0.01). The CCT at 1wk after operation in the suture group was greater than that before operation and at 3mo after operation(all P<0.01), and there was no significant change in CCT before and after surgery in the sutureless group. During follow-up period, the total complication rate in the sutureless group was lower than that in the suture group(26% vs. 38%, P>0.05).CONCLUSION:
25G vitrectomy combined with intraocular lens sutureless scleral tunnel interlamellar fixation in the treatment of complete lens luxation has shorter operation time, faster postoperative visual acuity improvement and fewer postoperative complications.
