Abstract Details

Purpose:

To determine the visual outcome, intraocular lens (IOL) stability and posterior capsule opacification (PCO) rate of an open loop hydrophobic acrylic intraocular lens.

Setting:

Vienna Institute for Research in Ocular Surgery, Hanusch Hospital, Vienna, Austria

Methods:

The double-blind randomized study included patients who underwent standard cataract surgery and received either the hydrophobic acrylic IOL (iPure, PhysIOL, Belgium) or the hydrophobic acrylic control IOL (Tecnis ZCB00, Johnson&Johnson, USA). Subjective refraction, uncorrected and best corrected distance visual acuity (UDVA, CDVA), slit lamp examination, IOL tilt and decentration measurements (Purkinje meter) and PCO grading using retroillumination images and automated image analysis software (AQUA, Austria) score, were evaluated for both groups at intervals of 1 year and 2 years after surgery.

Results:

From the total number of 50 patients, 31 completed the two-year follow-up, 16 in the study group and 15 in the control group. No adverse events were observed during the period. For the study group, the CDVA was 57.1 letters (SD: 3.8) while for the control group, 49.6 letters (SD: 7.8). The AQUA score for the study group was 2.1 and for the control group 1.4. Mean IOL tilt in the study group was 2.9° (SD: 1.8) and 5.0° (SD: 4.5) in the control group, whilst the mean decentration was 0.37 mm (SD: 0.18) and 0.45 mm (SD: 0.3) respectively.

Conclusions:

The studied parameters revealed a good performance of the study IOL as compared to the control IOL. Both IOLs had good CDVA, small amount of tilt and decentration and none of the patients required laser capsulotomies during the follow up time of two years postoperative.
