Abstract Details



Purpose:

To report the safety, efficacy, predictability and stability of the Artiflex iris-fixated intraocular lens in myopic phakic eyes.

Setting:

Department of Ophthalmology, Hospital Pedro Hispano, Matosinhos, Portugal

Methods:

A retrospective non-controlled analysis of all patients submitted to Artiflex phakic intraocular lens (PIOL) implantation between May 2011 and May 2012, with a minimum follow-up time of 6 months, was performed. Uncorrected distance visual acuity (UVDA), best spectacle visual acuity (BSCVA), refraction, endothelial cell count and complications were registered to evaluate safety, efficacy, predictability and stability.

Results:

27 eyes of 18 patients with a mean spherical equivalent of -8,63D, ranging from -14,50D to -3,75D were analyzed. The mean follow-up time was 11 months. The mean log-Mar BSCVA improved from 0,07 ±0,06 D pre-operatively to 0,02D ±0,03D post-operatively with a safety index of 1,13 ± 0,14D. One Snellen line or more of BSCVA was gained in 74,1% of patients and two or more lines in 14,8%. The post-operative mean log-Mar UDVA was 0,02 and statistically not different from the preoperative BSCVA (p=0,74) with a efficacy index of 0,98 ±0,24 D. 88,9 of the eyes operated had post-operatively SE within +/- 0,5D and 96,3% between +/- 1D. The spherical equivalent and the UDVA remained stable since the first week of follow up and the BSCVA since the first month (p>0,05). The mean endothelial cell loss was 2,74%. The main complications registered were lens pigment precipitates which did not compromise visual acuity (n=3), intraocular pressure elevation (n=1), sectorial iris atrophy (n=1) and necessity of lens explantation in the context of inadequate UDVA due to astigmatism.

Conclusions:

Implantation of Artiflex PIOL’s in resulted in a predictable, effective, stable and safe correction of refractive error in myopic eyes.
