504 Étude des aberrations optiques de haut degré après Implantation d’un implant à support irien chez les patients aphaques

Abstract

Aim To investigate the influence of the secondary implantation site of the Artisan®/ Verisyse® iris-claw intraocular lens (IOL) on high order aberrations (HOAs) using wavefront analysis in aphakic patients. Materials and Methods Aphakic patients who had complicated phacoemulsification, leaving no capsular support, but good iris support and clear unwounded cornea were randomized for Artisan/Verisyse® implantation site either implanted retropupilarely or over the iris. Wavefront aberrations were measured using the IRX3 Hartmann-Shack aberrometer at 4mm pupil aperture diameter. Results Best corrected visual acuity was significantly higher in the retropupillarely implanted group. There are no more wavefront aberrations with the retropupillary implantation technique of the Artisan/Verisyse® than with the classic anterior one and obtained visual acuity is equal or better. Discussion Considering that our patients were free from any corneal condition and that preoperative wavefront aberrometry showed no significant difference between the two groups, the optical quality results obatined with both implantation technique are comparable. Implantation of the Artisan/Verisyse® behind the iris seems as effective or better than “classic” implantation in the anterior chamber. Conclusion Wavefront aberrometry helped us validate this new IOL implantation technique that is more respectful of the anatomy and may be considered as a good alternative to anterior chamber implantation in aphakic patients.
