Abstract Details

Purpose:

To evaluate the endothelial cells loss after phakic intraocular lens implantation at 1 year of follow up according to iris configuration assessed pre and postoperatively with the anterior segment OCT (AS-OCT).

Setting:

Oftalmosalud, Lima, Perú

Methods:

Prospective, cohort study included 60 eyes of 35 patients, who underwent phakic IOL implantation (Artisan,Ophthec) for surgical correction of myopia at Oftalmosalud Instituto de Ojos, Peru, between July 2016 to July 2018. Pre and postoperatively at 1 year of follow up, endothelial cell density was performed using  specular microscopy. Eyes were divided into 3 groups: plane, concave and convex according to iris configuration assessed with the AS-OCT.  Safe distance was defined as the minimum distance between the edge of the optic and the endothelium. Statistical analysis was performed using the R program, Wilconcox signed rank test and Kruskal Wallis test.

Results:

Mean endothelial cells loss were -305.63±348.4 (11%) , -197.82±185.86 (7.5%) and -205.79±192.94 (7.5%) cell/mm2 in the concave, convex and plane group respectively. (P=0.8807).

Conclusions:

The rate of endothelial cells loss after 1 year of implantation of phakic intraocular lenses is not associated with the configuration of the iris.
