Purpose:Haptic repositioning during flanged intraocular lens (IOL) fixation can be difficult, and the haptic requiring repositioning may be at increased risk of excessive bending or breakage. This study aimed to report double-needle haptic repositioning technique outcomes for the aforementioned difficulty during flanged IOL fixation.Methods:This retrospective case series included seven eyes requiring haptic repositioning during flanged IOL fixation. The method features reinsertion of an already externalized haptic into the needle lumen followed by a needle-haptic complex internalized through the original tract into the eyeball. Thus, an adequate configuration for contralateral haptic can be achieved for insertion into the needle lumen to create a double-needle condition before both haptics are successfully externalized.Results:The median follow-up duration was 24 months (range, 4-24 months). Postoperatively, the IOL was well-centered, and corrected distance visual acuity improved from 20/320 (20/4,000-20/70) to 20/50 (20/250-20/20). No intraoperative or postoperative complications were noted.Conclusion:The technique produced encouraging results in patients undergoing haptic repositioning during flanged IOL fixation. This technique could potentially reduce haptic overbending risk and facilitate haptic adjustment. Further studies are needed to confirm the feasibility of the technique.
