Abstract Details


To evaluate postoperative astigmatism with regard to the deviation of lens alignment in eyes implanted with toric iris-fixated phakic intraocular lens for the correction of myopic astigmatism. The efficacy, predictability, safety and complications of this procedure were analyzed.


Department of Ophthalmology, Centro Hospitalar Lisboa Central, Lisbon, Portugal


Retrospective analysis of data from patients implanted with phakic toric iris-fixated intraocular lens (Artiflex® and Artisan®) at our department from 2009 to 2013. Anterior segment photography was taken postoperatively and lens alignment deviation was calculated. Other main parameters evaluated were uncorrected and corrected distance visual acuities, refraction, slitlamp biomicroscopy, tonometry, topography and central endothelial cell count (ECC).


The study enrolled 30 eyes of patients with ages from 26 to 47. Safety and efficacy indexes were positive. Most of our patients had a residual astigmatism between 0,25-0,75. There was no relationship between small lens alignment deviations and expected astigmatism.


Small lens alignment deviations with phakic toric iris-fixated intraocular lens have little effect on the final astigmatism. This procedure is an effective, predictable and safe solution for the correction myopic astigmatism.
