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 0.63 decimal or better were included. Patients requiring an IOL power outside the range of 15.0 to 27.0 dioptres were 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:

100 patients were included in the study. In 100 eyes of 77 patients a complete data set was achieved. Mean age was 71.7 years ranging from 51 to 89 years. The mean absolute rotation was 2.1 degrees (standard deviation, 1.7) at 6 months (1h – 6 months postoperatively). IOL rotation was less than 3 degrees and less than 6 degrees in 74% and 98% of all cases, respectively. 98% achieved a BCVA of 0.63 or better, 95% of 0.8 and 81% of 1.0 or better.

Conclusions:

The new YST0.00 hydrophobic acrylic posterior chamber single piece IOL shows excellent rotational stability, good post-operative BCVA and good safety results.
