Abstract Details
Purpose:
To compare neodymium:YAG (Nd:YAG) capsulotomy rates following implantation of two diffractive trifocal intraocular lenses (IOLs).
Setting:
Clinica Baviera Madrid, Instituto Oftalmológico Europeo, Madrid, Spain
Methods:
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.
Results:
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).
Conclusions:
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.
