Flapless and sutureless intrascleral fixation of posterior chamber intraocular lens for correction of aphakia

Abstract

A new intrascleral fixation technique for a standard 3-piece posterior chamber intraocular lens (PC IOL) using a simple guide is described. To secure the haptics, 27-gauge scleral tunnels are created. Both haptics are secured extraocularly. The leading haptic of the PC IOL placed in the cartridge is released partly and introduced into the lumen of the guide. The PC IOL is inserted into the eye, and the leading haptic is externalized by pulling the guide gently through the 27-gauge sclerotomy site. The trailing haptic is externalized using the same procedure. This technique facilitates achieving minimally invasive sutureless intrascleral PC IOL fixation.

A modified intrascleral intraocular lens fixation technique with fewer anterior segment manipulations: 27-gauge needle-guided procedure with built-in 8–0 absorbable sutures

“…The various intrascleral IOL fixation techniques can be broadly classified as either sutured or sutureless. Sutureless techniques for scleral IOL fixation have advantages because they do not lead to suture degradation, late IOL dislocation caused by broken sutures or other suture-related complications [11]. The critical difference between these techniques is the manner in which the haptics of the IOL are handled [22].…”

“…Sutureless techniques might result in haptic damage or dislocation from the intrascleral tunnel, but do not have suture-related complications. These techniques are less time consuming, easier to perform, and retain the advantages of intrascleral IOL fixation [11, 12]. Sutureless intrascleral IOL fixation technique was first formulated by Gabor and Pavlidis in 2007 and further detailed by Agarwal and colleagues.…”

Diagnostic imaging versus surgical procedure: intra- and postoperative OCT evaluation of sutureless scleral-fixated intraocular lens implantation and possible related complications

“…Sutureless intrascleral fixation techniques rely on intrascleral haptic fixation in order to ensure stability of the IOL [32]. Various techniques have been developed to obtain haptic fixation that can be obtained by creating a scleral flap or a scleral tunnel [33]. In order to carry out the great majority of these techniques, it is essential to dispose of special forceps that enable the surgeon to clutch the lens' haptics, put them in place and then externalize them through sclerotomy.…”
