Abstract Details

Purpose:

To compare visual results, reractive and complications of Artisan iris-claw intraocular lens (IOL) implantation versus three different secondary IOL procedures for the treatment of aphakic eyes.

Setting:

Vinalopó University Hospital, Ophthalmology Service, Cataract and Retinal Unit.

Methods:

In this retrospective comparative case series, 96 eyes of 96 patients who underwent secondary IOL implantation for correction of aphakia between 2010 and 2015 were enrolled. Patients were divided into four groups based on the secondary IOL implantation procedure. Group A: Artisan iris-claw IOL. Group B: capsular bag remains IOL. Group C: iris sutured IOL. Group D: sulcus-fixated IOL. All patients were followed up for a minimum period of 6 months. Data were collected regarding aphakia etiology, preoperative best corrected visual acuity (BCVA), postoperative BCVA and postoperative complications, and were compared. The statistical analyses were performed using SPSS Statistics.

Results:

Out of the 96 patients (69.8% male, 30.2% female), mean age was 77.04±9.13 years. Most frequent causes of aphakia were late luxated lens into the vitreous (59.4%) and complications during cataract surgery (36.5%). Mean preoperative logMAR BCVA was 1.5±0.76, no statistically significant differences between groups. B group obtained the best postoperative BCVA (0.23±0.26logMAR) (p>0.05). 59.4% of patients obtained a postoperative BCVA less than 0.3logMAR. Most common complication was cystic macular edema (CME)(15.6%), being more frequent in group A (p<0.05). Second complication was ocular hypertension (11.5%), no statistically significant differences between groups. Endothelial descompensation and panuveitis occurred in 7.3% of cases.

Conclusions:

Both the secondary Artisan iris-claw IOL implantation as the other three surgical techniques have demonstrated a low incidence of complications and acceptable visual results,with a postoperative BCVA less than 0.3logMAR in more than half of the eyes. The group B got the best visual results and the lowest percentage of complications,so secondary IOL implantation in sulcus on capsular remains is considered the technique of choice if conditions permit it. In the absence of capsular support,the secondary Artisan iris-claw IOL implantation has shown similar results than the other two,being a less invasive procedure with shorter operating times and shorter learning curve.
