Abstract Details


To compare neodymium:YAG (Nd:YAG) capsulotomy rates following implantation of two diffractive trifocal intraocular lenses (IOLs).


Clinica Baviera Madrid, Instituto Oftalmológico Europeo, Madrid, Spain


This multicentre, retrospective analysis included patients who underwent uncomplicated cataract surgery and were implanted with a diffractive trifocal IOL: FineVision MicroF (PhysIOL sa, Belgium), AT Lisa tri 839MP (Carl Zeiss AG, Germany). All surgeries were performed during the same period. Postoperative follow-up period was at least one year. Chi square and Kaplan Meier analysed non-parametric estimates for survival/failure functions. Wilcoxon (Breslow) test compared Nd:YAG capsulotomy rates between the two groups.


3387 eyes were implanted with FineVision MicroF and 1743 with ATLisa tri839MP; there were no statistical differences in age, axial length or IOL power between groups. Nd:YAG capsulotomies were necessary in 330 eyes (9%) in the FineVision group and 408 eyes (23%) in the ATLisa tri group (p<0.001). The probability of having Nd:YAG up to 9 months postoperatively was equal for both lenses. Thereafter, Nd:YAG capsulotomy rate increased with ATLisa tri839MP, reaching a probability of 35% after a follow-up of 34–44 months, whereas with the FineVision MicroF IOL it stabilized at 14%. Differences in survival/failure functions were significant (p<0.001).


Eyes implanted with the Finevision Micro F IOL required significantly fewer Nd:YAG laser capsulotomies than those with the AT Lisa tri 839MP during the first years post-implantation. The design of the IOL platforms could account for these differences.
