Abstract
PURPOSE: To describe a flapless/grooveless technique for four-point refixation of a dislocated intraocular lens (IOL) with four fenestrated haptics. METHODS: An intraocular suture looping technique was performed with the assistance of two 27-gauge needles. A looping needle was passed into the eye through paracentesis and was used to loop both fenestrated haptics on the same side with an 8-0 polypropylene thread. A guiding needle was used to guide the looping needle out of the eye at the scleral fixation sites. After looping each pair of fenestrated haptics on nasal/temporal sides with 8-0 polypropylene sutures, the IOL was refixated by definitive knotting. The exterior suture ends were buried into the sclera without the creation of scleral flaps/grooves. RESULTS: The technique was employed in four eyes (three patients). The mean postoperative follow-up period was 13.8 ± 2.2 months. Postoperatively, the IOLs of all the eyes remained well positioned and stable. The postoperative visual acuities of all the eyes were improved. No suture erosion, hypotony, scleral atrophy, chronic inflammation, retinal tears, and/or detachments were observed within the follow-up period. CONCLUSION: The present technique provides minimal surgical invasion for the transscleral refixation of a dislocated IOL with four fenestrated haptics.
