Rigid toric phakic IOLs (pIOLs) have been shown to be an effective option for the correction of ametropia and astigmatism,6-10 as they are rotationally stable.8,11 These pIOLs require, however, a relatively large incision, which may induce corneal astigmatism.12
In order to minimise the effect of corneal incision size, there are flexible and foldable designs that may be inserted through smaller incisions. The difference in the lens material gives certain differences in optical quality as reported by some authors,13,14 but these are not enough to translate into significant differences in visual performance.15
