  • PURPOSE: To evaluate the refractive outcomes of iris-fi xated toric phakic intraocular lens (pIOL) in the surgical correction of myopic astigmatism.

    SETTING: Department of Ophthalmology, Centro Hospitalar Lisboa Central. Lisboa, Portugal.

    METHODS: Retrospective analysis of data from patients who underwent toric iris-fi xated pIOL (Artifl ex® and Artisan®) implantation in Centro Hospitalar Lisboa Central between 2009 and 2013. Th e main parameters evaluated were best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), manifest refraction, intraocular pressure (IOP), central endothelial cell count (ECC) and complications.

    RESULTS: Th e study enrolled 25 eyes of patients aged from 24 to 47 years. An improvement of one or more Snellen lines was achieved in 20 patients (80%), with no cases of BCVA loss. All patients achieved an UCVA of 0.5 or better, with mean UCVA 0.92 ± 0.12.

    Safety and effi cacy indexes were 1.17 and 1.10, respectively. Spherical equivalent decreased from −12.69 ± 3.39 D to −0.78 ± 0.74 D, with a reduction in absolute cylinder from −2.51 ± 0.96 D to −0.62 ± 0.48 D. Th ere were no major complications. However, a transitory IOP increase to 25 mmHg was measured in one patient, pigment deposits were observed in 10 patients (60%), and an overall mean ECC loss of 8.7% was found.

    CONCLUSION: Toric iris-fi xated pIOL is an excellent solution for selected patients with moderate to high myopic astigmatism.
