Abstract Details

Purpose:

To retrospectively evaluate our results of Artisan toric ® phakic intraocular lens (pIOL) implantation, performed by the same surgeon, during two years, in eyes with compound myopic astigmatism.

Setting:

Artisan toric phakic intraocular lenses (pIOLs) are considered efective, safe and predictable for the correction of astigmatism associated with myopic spherical refractive defects.

Methods:

We analysed 28 eyes of 18 patients, 93 % female, with a mean age of 34,9 (± 3,8) years old, in which an Artisan toric pIOL was implanted to correct a compound myopic astigmatism.

Results:

Before surgery, the mean sphere was -8,23 ± 4,92 D, the mean cylinder was -3,52 ± 0,79 D, and the mean spherical equivalent was -9,99 ± 4,88 D; the best spectacle-corrected visual acuity (BSCVA) was 0,65 ± 0,16; the mean endothelial cell count (ECC) was 2722 ± 213. Six months after surgery, the mean spherical equivalent was -0,31 ± 0,38 D (p< 0.001), the mean sphere was +0,52 ± 0,54 D, and the mean cylinder was -1,67 ± 0,79 D (p< 0.001). The BSCVA was 0,77 ± 0,13 (p < 0.001); 65 % of eyes gained 1 or more Snellen lines. Regarding spherical equivalent, 96 % of eyes were within 1 D of emmetropia. The efficacy index was 0,99, and the safety index was 1,28. The mean ECC was 2684 ± 309. No important complications were found; one patient was submitted to LASIK for correction of residual ammetropy.

Conclusions:

In our study, Artisan toric pIOL implantation was safe and effective in the correction of compound myopic astigmatism, in line with the published results. FINANCIAL DISCLOSURE?: No
