To describe a new technique for repositioning a subluxated scleral-fixated rigid intraocular lens (IOL).
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.
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.
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.].
