Abstract
BACKGROUND: The video describes a technique in scleral fixation intraocular lens (SFIOL) surgery that is very simple and easily reproducible by any novice surgeon. PURPOSE: This technique may serve as a simple option for tucking the haptic of a multipiece IOL into the sclera without the need for the scleral flap, scleral pocket, forceps, glue, or flange. SYNOPSIS: The two most crucial steps in scleral fixation intraocular lens (SFIOL) surgery are 1) the exteriorization of the haptic, and 2) the fixation of the exteriorized haptic. The first half of the video describes the steps of our previously published technique of extraocular needle-guided haptic insertion technique (X-NIT), which simplifies the exteriorization step by shifting the intraocular hand-shake maneuver to an extraocular site. The second half describes a novel suture-guided haptic fixation (S-FIX) device, which simplifies the fixation step. S-FIX has three components: 1) a 380-micron spatulated needle, 2) a 5-o nylon suture thread, and 3) a polyimide tube. There are four steps involved in S-FIX: 1) docking of the exteriorized haptic into the polyimide tube, 2) pushing the docked polyimide tube into the eye, 3) suture bite starting from the point of sclerotomy, and 4) pulling the suture thread. As the suture thread is being pulled, the haptic along with the polyimide tube comes out and the haptic gets fixed into the narrow suture track. HIGHLIGHTS: The technique enhances the overall safety in SFIOL surgeries by avoiding haptic slips during exteriorization and fixation steps. Most anterior segment and novice surgeons do not perform SFIOL surgeries due to fear of fall of IOL. VIDEO LINK: https://youtu.be/ZoJBiw2SNaU.
