Abstract Details


To study the cumulative neodymium: YAG (Nd:Yag) laser rate after 5001 implantations during cataract surgery of 5 different hydrophilic acrylic MICS lens and evaluate influence of material and design.


Centre Ophtalmologique IRIDIS, Albi, France.


This retrospective study comprises all patients who were implanted between 2006 and the end of 2014 with one of the after 5 micro-incision IOLs: Akreos MICS and INCISE (Bausch and Lomb), CT Asphina (Zeiss), MicroSlim and Micro AY (PhysIOL). The postoperative follow-up ranges from 1 to 96 months. The cumulative Nd:Yag laser frequency rates in all groups were calculated, and the cumulative incidence rates were defined by Kaplan-Meier survival analysis and Mann-Withney test with a significance threshold of 0.05.


The 5-year survival percentage was 16.70% for the Akreos MICS (95% CI :10-28) ; 24.50% for the CT Asphina (95% CI :14-43) ; 61.50% for the MicroSlim (95% CI :55-68) ; 53.50% for the Micro AY (95% CI:49-59). At 5 years the survival rate is lower for Akreos MICS in comparison of 3 others groups p<0.001. The survival rate for MicroSlim is higher than other groups p<0.001 and the survival rate for CT Asphina is not statistically different than Micro AY p<0.228. 6 years analyse will be available.


There is no excessive PCO after MICS lens implantation. The cumulative Nd:Yag laser rates after micro-incision implantation were comparable for Micro AY and MicroSlim. The Akreos MICS lens shows the highest ND:Yag rate. The CT Asphina plate haptic design with square edge on periphery shows a low Nd:Yag rate at 3 years but increases dramatically after. The INCISE with is sharper barrier edge could give a lower PCO rate in the future.
