Abstract
Purpose:
To assess the rotational stability of two single-piece toric acrylic intraocular lenses (IOL) during the first postoperative month.
Methods:
This retrospective case series included 15 eyes (14 patients) with age-related cataract and corneal astigmatism ≥1.50 diopters [D]. Corneal astigmatism was measured using the Pentacam Scheimpflug system (Oculus) and IOL biometry was performed with laser interferometry (IOL Master). All eyes were analyzed after uncomplicated phacoemulsification with in-the-bag implantation of toric IOL (Hoya iSert 351; Rayner T-flex). Rotational stability of the IOL was assessed by comparison of images taken by the microscope video camera intraoperatively with retroillumination photographs at 1 month postoperatively.
Results:
The overall mean absolute IOL rotation was 7.67 degrees ± 5.54 (SD). The mean absolute IOL rotation was 5.60 degrees ± 3.21 (SD) for Rayner T-flex IOL and 6.11 degrees ± 4.53 (SD) for Hoya iSert 351 respectively.
Conclusions:
Both investigated acrylic toric IOL seem to be rotationally stable with just mild IOL rotation in the first postoperative month and can be recommended for the correction of astigmatism during cataract surgery.
