[Refractive stability of foldable intraocular lenses].

Purpose: To compare the refractive stability of different kind of foldable intraocular lenses.

Method: There was performed a two years (mean follow-up 7,4 +/- 1,2 months) prospective interventional case series study on 108 with senile cataract, without another ocular pathology which underwent cataract surgery by phacoemulsification and implantation of foldable intraocular lens (the same surgeon). Each patient had their refractive status measured at the 1-month postoperative visit, 3-months and at the 6-months follow-up visit. The results have been statistically analyzed using the Wilcoxon test.

Results: The postoperative refractive results were correlated with IOL design and material. The acrylic hydrophobic foldable intraocular lens with rigid haptics was more likely to move to hypermetropia and the acrylic hydrophobic foldable intraocular lens with pliable haptics showed minimal myopic movement.

Conclusions: On long-term, the 1-piece acrylic hydrophobic IOL with soft acrylic loops had the most stable refractive results.
