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 Lodève, 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 (0.1D). The mean absolute rotation of the implant was 2.5 ± 2.6°. The position of the center of the implant relative to the pupillary center expressed as a vector was 0.01 mm at 70°.
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.
