PURPOSE: To evaluate a novel surgical technique for transscleral fixation of the intraocular lens (IOL) with four hollow haptics using 8-0 polypropylene suture looping and overhand knot.
METHODS: An 8-0 polypropylene suture was tied to a 10-0 polypropylene suture with an overhand knot. One set of 8-0 polypropylene suture was then passed through the IOL four haptics. The suture knot was buried by rotating into the sclera tunnel. Best-corrected visual acuity, intraocular pressure, and complications were determined.
RESULTS: The IOLs were fixed with using an 8-0 polypropylene suture in 13 eyes of 11 patients with aphakia and dislocated crystalline lens. The mean preoperative corrected distance visual acuity was 0.71 ± 0.58 logarithm of the minimum angle of resolution (Snellen 20/103), and it improved to 0.24 ± 0.25 logarithm of the minimum angle of resolution (Snellen 20/35) at the final follow-up ( P < 0.05). No vitreous hemorrhage, hypotony, suture exposed, and pupillary capture of the IOL were observed in any of the patients.
CONCLUSION: The authors have developed a new technique for transscleral IOL fixation with one set of an 8-0 polypropylene suture tied to a 10-0 polypropylene suture with an overhand knot. The overhand knot offers the opportunity to use an 8-0 polypropylene suture for the long-term safety and may not require the surgeon to learn any new technique.
