Abstract
Purpose
To report the results of scleral suture fixation using a hydrophilic acrylic intraocular lens (IOL) with 3 hollow haptics through a small corneal incision, the Triple Cow-Hitch Method.
Case summary
Three-point suture fixation of a XL Stabi ZO IOL was performed in 5 eyes of 5 patients with aphakia after penetrating keratoplasty (PKP), vitrectomy and subluxated lens extraction. Postoperatively, the corrected distance visual acuity and spherical equivalent improved in all measured eyes. There were no cases of pigment dispersion or cystoid macular edema (CME).
