Abstract:

Objective To evaluate safety and efficacy of sutureless intrascleral fixated intraocular lens (IOL) implantation for patients with insufficient capsular support. Design Retrospective case series. Participants 42 eyes of 41 patients who underwent sutureless intrascleral fixated IOL implantation in Beijing Tongren Eye Center during August 2015 to May 2018. Methods Gender, age, postoperative complication, uncorrected visual acuity (UCVA) , best-corrected visual acuity (BCVA) and refractive error were reviewed and analyzed statistically.  Main Outcome Measures Complication, UCVA, BCVA, and refractive error. Results Postoperative complications included anterior chamber fibrin exudation in 3 eyes (7.1%)， mild hyphema or vitreous hemorrhage in 4 eyes (9.5%)，transient high intraocular pressure (IOP) in 6 eyes (14.3%) and low IOP in 8 eyes (19.1%)，iris capture of the IOL in 2 eyes (4.8%)，exposure of the haptic of  IOL in 1 eye (2.4%). There were significant statistical differences between the postoperative UCVA (0.93±0.75，LogMAR) and BCVA (0.21±0.23, LogMAR) with preoperative UCVA (1.69±0.38, LogMAR) (Z=-5.652，P=0.000) and BCVA(0.35±0.22, LogMAR) (t=6.290, P=0.000). At the last postoperative visit, mean refractive errors were (0.85±0.47) DS; mean astigmatisms were (1.20±0.51)DC.  Conclusion Sutureless intrascleral fixated IOL implantation technique provides good IOL fixation with reliable VA improvement without severe postoperative complication. It is safe and useful for IOL implantation in eyes without sufficient capsule support.
