Abstract Details

Purpose:

The aim of this study is to evaluate the safety, predictability and leading reason to perform bilensectomy (phakic intraocular lens (IOL) explantation + cataract surgery + posterior chamber IOL implantation) for phakic iris claw IOL.

Setting:

Alicante, Spain and Porto Portugal.

Methods:

This is a retrospective study that included 45 eyes that had bilensectomy of an iris claw phakic IOL. Thirty-two eyes had a follow up of 1 year and 44 eyes had a follow up of 6 months. The main cause of bilensectomy and the following parameters were assessed: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), endothelial cell count before and after bilensectomy. Also the efficacy and safety index were assessed.

Results:

The main cause of bilensectomy was cataract development in 25 eyes, followed by endothelial cell loss (18 eyes), 2 eyes had both cataract and endothelial cell loss. The mean time between phakic IOL implantation and bilensectomy was 130 months. At 6 months follow up the efficacy index was 0,9 and the safety index was 1.4; at 1 year the efficacy index was 0.9 and the safety index was 1.3. Mean endothelial cell count before surgery was 1446 and after bilensectomy was 1071. At 1 year follow up mean UDVA was 0.4 and CDVA was 0.6.

Conclusions:

All patients with a phakic IOL will eventually undergo bilensectomy, with this study we can conclude that bilensectomy for phakic iris claw IOL is a safe and efficient procedure. One patient had a nasal retinal detachment 11 months after the bilensectomy. The mean UDVA and CDVA following bilensectomy was reflected by the ocular comorbidities of these patients like high myopia; however, a highly significant improvement of the visual acuity was achieved after surgery.
