Abstract Details

Purpose:

The purpose of this study was to assess the clinical outcome and higherorder aberrations after implantation of a hydrophilic toric intraocular lens (tIOL). Methods: A total of 30 eyes of 22 patients were enrolled in this prospective, singlecenter study. The Torica MC 6125T (HumanOptics, Erlangen, Germany) was implanted after phacoemulsification. The tIOLs were determined with the HumanOptics online toric calculator. The preoperative marking of the implantation axis was carried out with the adjustable pendulum marker (Geuder, Heidelberg, Germany) and supported intraoperatively with Callisto Eye (Zeiss, Jena, Germany). The aberrometry was performed with iTrace (Tracey Technologies, Houston, Tx, USA). Postoperative evaluations were performed after one day, one week, one month and three months.

Setting:

Charit�Ã�© �â�€�“ University Medicine Berlin, Department of Ophthalmology, Augustenburger Platz 1, 13353 Berlin, Germany

Results:

The mean age of the patients was 63.6 �Â�± 15.2 years. Preoperatively, the corneal astigmatism was 1.7 Diopters (D) �Â�± 0.5 D (Range 1.25 D to 3.25 D). One month after surgery the astigmatism was reduced significantly to 0.59 D �Â�± 0.43 D (p < 0.05). Three months after surgery the astigmatism was 0.58 D �Â�± 0.48 D. The mean monocular uncorrected visual acuity increased from 0.26 �Â�± 0.12 logMAR before surgery to 0.07 �Â�± 0.15 logMAR after one month and to 0.00 logMAR (�Â�± 0.09 logMAR) after three months. There was no significant correlation between preoperative and postoperative higher-order aberrations. The difference between the calculated and the actual toric axis was 4.30 �Â�± 4.07 degrees. No complications occurred, neither intraoperatively nor postoperatively.

Conclusions:

The Torica MC 6125T provided a good clinical outcome and can be regarded as an appropriate and safe toric intraocular lens for the reduction of corneal astigmatisms.
