Abstract Details

Purpose:

To evaluate the rotational stability and performance of a new blue light-absorbing hydrophobic acrylic posterior chamber single-piece intraocular lens (IOL) during the first 6 postoperative months.

Setting:

Vienna Institute for Research in Ocular Surgery, A Karl-Landsteiner-Institute, Hanusch Hospital, Vienna, Austria.

Methods:

In this study, patients with age-related cataract and potential postoperative best corrected visual acuity (BCVA) of 0.2 log MAR or better were included. Patients requiring an IOL power outside the range of 15.0 to 27.0 dioptres had to be excluded. Patients received a single-piece non-toric hydrophobic acrylic IOL with an axis mark (YST0.00; Nidek). One hour, 1 week and 6 months after surgery, retroillumination photographs were obtained to assess the rotational stability of the IOL. Secondary endpoints were distance BCVA and adverse events.

Results:

135 eyes of 100 patients were included in the study. A preliminary analysis showed a mean absolute rotation of 1.6 degrees (standard deviation, 0.9) at 1 week (1h – 1 week postoperatively), and a mean absolute rotation of 1.1 degrees (standard deviation, 0.9) at 6 months (1h – 6 months postoperatively). Detailed final results will be presented.

Conclusions:

The new YST0.00 hydrophobic acrylic posterior chamber single-piece IOL shows excellent rotational stability.
