Abstract Details

Purpose:

To describe a new surgical technique for retropupillary implantation of iris-claw intraocular lens(IOLs) for aphakia. The surgical management of aphakia without capsular support is often complex,there is still no optimal surgical approach in these cases.The options include anterior chamber IOLs,iris-sutured or scleral-sutured posterior chamber IOLs,scleral tunel IOLs,and iris-claw IOL.Iris-claw IOLs have been shown to be a safe choice for secondary IOL implantation in aphakic eyes with extended zonulolysis or without capsular support.Although,originally designed for fixation on the anterior surface of the iris,case series showed advantages of fixating these IOLs retropupillary,mostly,by minimizing corneal endotelial cell loss and maintaining anterior chamber depth.

Setting:

Hospital Beatriz Ângelo

Methods:

We report cases of aphakic eyes undergoing retropupillary iris-claw IOLs enclavation (Artisan®). A complete anterior pars plana vitrectomy or an extensive preceding anterior vitrectomy as well as an intact iris are prerequisites to a retropupillary implantation of an iris-claw IOL. Special instruments for the implantation and fixation of these IOLs are available to optimize the operative procedure. However, our technique is simple and unprovided of special instruments, it requires only a 27G or a 30G needle in the anterior chamber to support the enclavation surgical step of iris-claw IOLs.

Results:

IOL was properly positioned retropupillary and maintained stable and centered in our case series. There was no intra or postoperative complications.

Conclusions:

The surgical technique described in this paper is relatively simple, quick and easy to perform, using only a 27G or 30G needle.
