Abstract Details

Purpose:

To examine the visual outcomes following bilateral implantation of a new trifocal IOL.

Setting:

St-Godfriedstraat 8, Sint-Truiden, Belgium

Methods:

This study is comparing the outcomes after 74 consecutive implantations of 37 patients from February 2013 to February 2014 with a new trifocal IOL (POD FineVision, Physiol, Belgium) with a control group made of 94 eyes of 47 patients implanted with the FineVision. The new IOL (POD FineVision ) is 26% hydrophilic IOL and its optic is similar to her parent IOL (FineVision MicroF, Physiol, Belgium) in terms of optics but presents a new design that prefigures the toric version for the FineVision optics. This non-randomized controlled study was planned to determine the safety and efficiency of the new POD F IOL in standard surgery. All patients were older than 50 and suffering from bilateral cataract. They were motivated for spectacle independence with realistic expectations. Patient refractive and visual outcomes as well as subjective evaluation with regards to UCVA at near, intermediate and far distances, spectacle independence and contrast sensitivity were noted, analyzed and results are reported and compared. Group normality was achieved by achieving a Kolmogorov-Smirnov test over the age and IOL power. The Chi-squared test with a type I error of 0.05 was achieved to compare groups.

Results:

Groups were normally distributed (p<0.05). The postoperative monocular corrected distance visual acuity was 0.09±0.08 LogMAR in both groups (p>0.05). The safety index was greater than 1 in all patients. Similarly, near vision was excellent in both groups. The postoperative refractive spherical equivalent was 0.03±0,23 D, with only 2 outsiders. All patients reported high spectacle independence and were bearing very well their dependence to light. No photic phenomena was observed in one cohort compared to another.

Conclusions:

Patients satisfaction was high with both the FineVision and the POD FineVision. The change of biomaterial from 25% to 26% did not change the patient’s perception of the trifocal. The new IOL platform also insured a good self centration, as it was for the FineVision
