Abstract: Purpose. - To assess the rotational stability and centration of a single-piece hydrophilic acrylic intraocular lens (IOL) during the first postoperative year. Setting. - Clinique Beausoleil, 117, avenue de Lodeve, 34070 Montpellier, France. Design. - Retrospective case series. Method. - The POD AY 26% monofocal aspheric yellow intraocular lens is designed to facilitate its intraoperative orientation within the capsular bag. This study consists of a retrospective analysis of 117 consecutive eyes implanted with this IOL to determine its postoperative stability. Data collected include ocular biometry, patient history, IOL power, pre- and postoperative visual acuity and refraction, and slit lamp photos after one and three weeks, and 3 and 12 months. Results. - Mean postoperative visual acuity was 0.95 after 3 months and remained stable after 1 year. The refraction was also stable over time, although a slight effect related to corneal healing could be observed (0.1 D). The mean absolute rotation of the implant was 2.5 +/- 2.6 degrees. The position of the center of the implant relative to the pupillary center expressed as a vector was 0.01 mm at 70 degrees. Conclusion. - This new IOL design is as stable as a C-Loop IOL but provides much better maneuverability during implantation. It provides physiologic centration and good rotational stability over 1 year. It would be a perfect platform for a toric optic. (C) 2013 Published by Elsevier Masson SAS
