Abstract Details

Purpose:

To compare the long-term visual outcomes and safety of scleral-fixated posterior chamber and anterior chamber iris-claw intraocular lenses (IOLs) implantation.

Setting:

Central Lisbon Hospital Center, Ophthalmology Department

Methods:

Medical records of 7 eyes of 7 consecutive patients who had scleral-fixated posterior chamber IOL implantation and 10 eyes of 9 consecutive patients with anterior chamber iris-claw IOL implantation between 2009 and 2014, with more than 1 year of follow-up were retrospectively analyzed. Indication for IOL implantation was aphakia after cataract extraction and trauma. Demographic data, best corrected visual acuity (BCVA) previous and after surgery and complications during the follow-up period were studied.

Results:

There were no intraoperative complications. Patients submitted to scleral-fixated IOL implantion had a mean pre-operative VA of 0.7logMAR and pos-operative of 0.3logMAR (mean VA increase of 0.6logMAR). Patients submitted to iris-claw IOL implantation had a mean pre-operative VA of 0.8logMAR and post-operative of 0.2logMAR (mean VA increase of 0.3logMAR). Follow-up was secured in average 5.4 years and all IOLs are well fixated and stable. 6 of the 17 eyes had a pos-operative complication, including high intraocular pressure and cystoid macular oedema, that were managed with topical therapy. 1 eye with iris-claw IOL implantation had a desenclavated lens haptic.

Conclusions:

Scleral-fixated and iris-claw IOLs implantation provide good visual rehabilitation of aphakic eyes without capsular support. In most of the cases, there is an improvement in BCVA after surgery, but anterior chamber iris-claw IOL may entail superior visual outcomes. The choice of surgery procedure is dependent to surgeon experience and eye's conditions.
