Abstract Details


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.


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


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.


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.


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
