Single-string, closed-loop fixation modification to reposit a dislocated triple-looped haptic intraocular lens

Abstract

A technique using the single-string, closed-loop fixation method to reposit dislocated triple-looped haptic IOL-capsular bag complexes is described. The long needle or curved needle with 10-0 / 8-0 polypropylene suture and 27 / 30g needle were used as the guide needle to pass through the fenestrated haptics for two times. The scleral interlaminar course was used as the fixed point. last, A fixation knot was created in the sclerotomy by the two ends of the thread to close the suture loop for IOL fixation. Another knot was created about 2 to 3 mm from the exiting point and was intrasclerally anchored by the aid of the attached needle.Four eyes from 4 consecutive patients were studied retrospectively; During all follow-up visits, the IOLs were well centered and stable, No suture erosion, hypotony, scleral atrophy, chronic inflammation, retinal tears, and/or detachments were observed.
