To assess the safety and efficacy of Novel Cannulated Suture Thread Device for Easy Scleral Fixation of a Multipiece Intraocular Lens (S-FIX)

Scleral fixation of a multipiece intraocular lens (SFIOL) is an established modality for surgical correction of aphakia. The two most crucial steps of SFIOL surgery are exteriorization of the haptic and fixation of the same intrasclerally. Various techniques have been described in the literature to constantly simplify these steps. Most techniques differ in the way the haptics are fixed. Appropriate and adequate fixation of the haptic of a multipiece intraocular lens inside the scleral groove is a key component in SFIOL surgeries. Conventional methods of fixing the haptic require either specialized forceps, additional surgical steps like scleral flap creation or additional consumables like bio fibrin glue. Here, we describe a novel cannulated suture thread device (S-FIX) for easy scleral fixation of a multipiece intraocular lens. The S-FIX technique does not require conjunctival peritomy, specialized vitreo-retinal forceps, flap, flange or glue. Aphakic patients who require SFIOL implantation will be recruited. after obtaining consent the SFIOL surgery will be done using S-Fix device. All intra-operative complications will be noted. Post-operative follow-up will be on day 1, day 14, and day 45. Post operative follow-up include Refraction, specular microscopy and OCT. ASOCT will be done on POD 45 and IOL tilt will be measured using image J software. All post operative complications will be noted.
