Abstract Details

Purpose:

The Reper intraocular lens (IOL)-artificial iris is a novel, acrylic-based device used to reduce symptoms and restore function in patients with absent or defective irises. As the first North American centre to use this device, we aim to contribute to the limited literature by reviewing our patient outcomes as well as the efficacy and safety associated with its use.

Setting:

University of Ottawa Eye Institute, Ottawa, Canada

Methods:

This is a retrospective chart review of patients undergoing implantation with the Reper IOL-artificial iris as standard of care by a single surgeon. Data on patient demographics, ocular and medical history, pre- and post-operative visual function and symptoms, as well as complications will be collected. The primary outcome measure is the degree of subjective reduction in photophobia. Secondary outcomes will include post-operative visual acuity and intraocular pressure (IOP), intra- and post-operative complications, and patient satisfaction with cosmetic outcome.

Results:

Three patients have undergone implantation of Reper IOL-artificial iris. Surgical indications included congenital aniridia and cataracts, traumatic iridodialysis, and intractable pain due to remote open globe trauma and anterior chamber IOL dislocation. Post-operatively, all three patients reported significant improvements in photophobia and cosmesis. Postoperative best-corrected visual acuity (BCVA) was either unchanged or improved (range 20/250 to 20/20) compared to pre-operative BCVA (range 20/400 to 20/20); and IOP was stable, ranging from 13 to 16. No intra-operative complications were encountered. Post-operative complications included transient corneal edema and choroidal thickening in one patient, which resolved by the one month follow up.

Conclusions:

Preliminary results suggest that Reper IOL-artificial iris implantation may be a safe and effective technique for improving photophobia and cosmesis in patients with iris defects.
