PURPOSE: To describe the facilitated trailing haptic externalization technique for intrascleral intraocular lens (IOL) fixation.
METHODS: In this technique, first the direction of the 4-5 mm tip of the trailing haptic is straightened with the help of forceps. After the second needle enters the posterior chamber, the edge of the IOL optic is pushed towards the opposite scleral tunnel with the needle. The trailing haptic approaching the center from the periphery and the straightened distal part of the haptic towards the direction of the needle facilitate the relatively easily and gently placing of the haptic into the lumen with a one-time use of forceps.
RESULTS: This technique was performed on 65 eyes of 58 patients, with a mean patient age of 53.0 ± 14.6 years (range, 22-78). No complications such as endothelial touch, vitreous loss, iris or ciliary body damage, and hyphema were encountered during surgery. The mean operation duration was 14.8 ± 2.3 min (range, 12-20). In the postoperative period, there was only mild postoperative anterior chamber reaction in all eyes. Postoperative transient intraocular pressure (IOP) elevation that responded well to topical antiglucomatous therapy was observed in only two cases (3%). No patient developed haptic exposure, IOL dislocation, iris capture, postoperative hypotony, vitreous hemorrhage, choroidal effusion, cystoid macular edema, or retinal detachment.
CONCLUSION: The facilitated trailing haptic externalization technique provides a safer, simpler, and minimally invasive surgery without significant complications while easing the surgical difficulties of the Yamane technique.
