BACKGROUND AND OBJECTIVE: To describe a new technique for repositioning a subluxated scleral-fixated rigid intraocular lens (IOL).
PATIENTS AND METHODS: The authors present a modified intraocular threading technique to tie a cow-hitch knot around the eyelet on the dislocated haptic of a scleral-fixated rigid IOL. This technique uses three small corneal incisions to eliminate the need for IOL externalization and minimized the size and number of wounds.
RESULTS: Three consecutive cases of subluxated haptics in two patients underwent this procedure. Postoperative IOL centration and alignment were satisfactory without tilt. No surgical-related complication was observed 1 year after surgery.
CONCLUSION: A rigid IOL could be repositioned to a desired axis and centration via this modified cow-hitch technique, with better IOL support as compared with a single tie. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:179-182.].
