Reper intraocular lens with artificial iris: implantation techniques and outcomes

Abstract

The authors describe the surgical techniques to implant a novel intraocular lens with artificial iris (Reper) in patients affected by traumatic aphakia and aniridia. Two surgical approaches are proposed: implantation by suture-loaded cartridge and “open sky” implantation combined with penetrating keratoplasty. The method of establishing the exact position of the scleral fixation points and the pre-assembly of the suture of Reper before its implantation are the main novel proposed surgical procedures. The rationale is to minimize surgical procedures in the anterior chamber and to prevent knot loosening and lens tilting. The simultaneous treatment of aphakia and aniridia with a single prosthesis, the stability of the Reper and the functional, anatomical and aesthetic outcomes obtained are the highlighted advantages in this study.

Risks and Complications Associated with Refractive Surgery

“…Second, surface corneal procedures, involving the ablation of anterior part only of the cornea, include photorefractive keratectomy (PRK) and laser-assisted sub-epithelium keratomileusis (LASEK) [19]. Third, lens procedures including implantable collamer lens (ICL) and refractive lens exchange (RLE) require an addition of artificial lens or replacement of the original lens [20,21]. And the last type of procedure is small incision lenticule extraction (SMILE) [16,22].…”

Utilizing 3D Printing Technology to Create Prosthetic Irises: Proof of Concept and Workflow

“…Modified capsular tension rings with black occluder paddles have also been utilized, and while these require smaller surgical incisions during implantation, they have a similar limitation of unacceptable cosmesis as black diaphragm intraocular lenses [10]. Reper devices (distributed by Ophtec BV, Groningen, The Netherlands) are made of foldable hydrophobic acrylic material with different color options available; however, the iris color and pattern are not customizable [11]. One of the challenges of iris implants is the accurate reproduction of a human iris with pigmented, layered texture with crypts and folds.…”

Novel surgical technique of sutureless artificial iris and intraocular lens scleral fixation using Yamane technique

“… 7 Recently, Ophtec launched their Model C0/1 (sulcus fixation with/without optical correction) and Model F0/1 (capsular bag fixation), produced by Reper (Reper-NN Ltd., Nizhniy Novgorod, Russia), which is a foldable acrylic iris-IOL available in a variety of 300 presets to choose from. 6 , 8 , 9 …”
