Minimally invasive sutured intraocular lens placement without conjunctival incision in aphakic post-vitrectomy eyes via 3mm incision and 25G anterior-irrigation

Abstract

Objective To evaluate the therapeutic efficacy of minimally invasive sutured intraocular lens placement without conjunctival incision in aphakic post-vitrectomy eyes via 3mm incision surgery and 25G anterior-irrigation.Methods Twenty patients(21 eyes)were aphakic post-vitrectomy eyes.Before the operation,the uncorrected distance visual acuity was from counting fingers to 0.1,and the best corrected visual acuity was from 0.1 to 1.0,All cases were performed the surgery which a Akreos foldable IOL was used to facilitate 2-point fixation through a 3mm incision,with 25G anterior-irrigating without conjunctival incision.Post-operation uncorrected visual acuity,best corrected visual acuity,IOP,diopter,IOL location and complication were observed.Results Followed-up 3-24 months post-operation,uncorrected VA was from 0.1-1.0,better than pre-operation,uncorrected VA and best corrected VA were both similar to pre-operation(P =0.526＞0.05,P =0.379＞0.05).Seventeen IOLs were good centration,2 IOLs with gently dislocation,2 IOLs with gently tilt and no one with the uncomfortable complains.Conclusions With 25 G anterior-irrigating,minimally invasive sutured intraocular lens placement without conjunctival incision in aphakic post-vitrectomy eyes via 3mm incision surgery is a safe,efficient and simple surgery,with small wound and recovery soon,no conjunctival scar.It provides good uncorrected visual acuity.
