Abstract Details

Purpose:

Compare the rotational stability of two IOLs with the same optics, different designs and materials

Setting:

Private practice Oftalmología avanzada, Madrid, Spain

Methods:

In this prospective randomised controlled trial, we compared the IOL rotation of an acrylic hydrophilic 26% trifocal IOL (PODFineVision, Physiol, Belgium) and the hydrophilic 25% trifocal IOL (FineVision/MicroF, Physiol, Belgium) with the exact same design for the optical zone. Twenty patients were randomized for the eye, one eye receiving the Micro F, the fellow eye implanted with the POD FineVision. The stability (rotation, centration and anteroposterior position) and performance – with respect to refraction - of a new IOL design (POD F) is compared to the previous design (Micro F). Visual acuity, straylight and aberrations were also tested.

Results:

Better centration was observed with the POD FineVision (p<0.05). Both IOL nevertheless showed excellent centration and rotational stability (<5° in all cases). Surprisingly, the visual acuity PODFineVision was better at 40 cm than the Micro F (p<0.05). The visual acuities were equivalent at 30 cm and 80 cm. Both IOLs showed corrected distance visual acuities of 0.00±0.00 LogMAR. Both aberrometry and OQAS for the two IOLs were in the normal range

Conclusions:

Both IOLs provided excellent visual outcomes. The better centration of the POD IOL seems to even improve the excellent outcomes of the MicroF
