Abstract Details

Purpose:

To assess the axial IOL position stability of the C-loop CT LUCIA 611P IOL compared to the CT ASPHINA 409MP four point haptic IOL following implantation.

Setting:

Hanusch Hospital Vienna

Methods:

100 eyes of 50 patients were included in this prospective fellow-eye study. All patients underwent cataract surgery with implantation of CT LUCIA 611P or CT ASPHINA 409MP (Carl Zeiss Meditec). The IOL implanted in each eye was chosen in a randomised manner. One inclusion criterion was a distance corrected visual acuity (CDVA) of ≤0.3logMAR. Pre-operative and post-operative examinations at 1 week (W1), one month (M1) and 4-6 months (M4-6) included monocular uncorrected distance visual acuity (UDVA) and DCVA and anterior chamber depth (ACD) measurements. Postoperatively at W1, M1 and M4-6 tilt, decentration, safety parameters and axial position were also evaluated.

Results:

4 month follow-up data will be presented. At present, 1 month data for all patient have been evaluated. UDVA at M1: 0.08+/-0.14logMAR for CT LUCIA-611P and 0.04+/-0.09logMAR for CT ASPHINA-409MP. CDVA at M1: -0.01+/-0.10logMAR for CT LUCIA-611P and -0.03+/-0.08logMAR for CT ASPHINA-409MP. The mean preoperative ACD was 3.14+/-0.37mm and 3.18+/-0.37mm for CT LUCIA-611P and for CT ASPHINA-409MP, respectively. Postoperatively, following CT LUCIA-611P implantation in 48 eyes, the mean baseline ACD at W1 was 5.47+/-0.64mm and at M1 was 5.74+/-0.53mm. Following CT ASPHINA-409MP implantation in 48 eyes, the mean baseline ACD at W1 was 4.42+/-0.46mm and at M1 was 4.61+/-0.39mm.

Conclusions:

The visual acuity and anterior chamber depth outcomes following implantation of these two IOLs, with different haptic designs and manufactured with different materials, are evaluated in this fellow-eye study. M1 interim results demonstrate excellent outcomes regardless of the IOL implanted, All patients are now included in the study and underwent their last visit. Final data (M4-6) will therefore be presented at the meeting. The main outcome of the study is the evaluation of axial IOL position stability of these two very different IOLs.
