Abstract Details


To study the cumulative neodymium: YAG (Nd:Yag) laser rate (capsulotomy for posterior capsular opacification) after 6519 implantations during cataract surgery of 6 different hydrophilic acrylic MICS lenses and 2 hydrophobic 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 2018 with one of the after 8 micro-incision IOLs: Akreos MICS and INCISE (Bausch and Lomb), CT Asphina 509 M/MP (Carl Zeiss Meditec), Synthesis (Cutting Edge) MicroSlim, Micro AY, MicroPure and PodEye (PhysIOL). The postoperative follow-up ranges from 1 to 156 months. The cumulative Nd: Yag laser frequency rates in all groups were calculated, and the cumulative incidence rates were defined by propensity score, Weighted Cox regression, Tuckey test, Kaplan-Meier survival analysis and Mann-Withney test.


The 2 years survival percentage was 100% for the INCISE (95% CI: 100-100); 74,11% for the Akreos MICS (95% CI: 68-79); 92,29% for the CT Asphina (95% CI: 90-94); 89,35% for the MicroSlim (95% CI: 86-92); 88,20% for the Micro AY (95% CI: 87-90) and 82,74% for the MicroPure (95% CI: 68-91). The 7 years survival percentage was 15,24% for the Akreos MICS (95% CI: 10-22); 30,12% for the CT Asphina (95% CI: 24-36); 67.59% for the MicroSlim (95% CI: 62-73); 50,02% for the Micro AY (95% CI: 47-53). Complementary statistical analysis will be done.


At two years the INCISE has the best result with no ND:Yag laser capsulotomy and despite his hydrophobic material the MicroPure doesn’t seem to decrease ND:Yag. The CT Asphina plate haptic design shows a low Nd:Yag rate at 3 years but increases dramatically after with a tendency to have a higher rate at 7 years. Akreos Mics have the lower survival rate. MicroSlim gives the best Nd: Yag survival rate perhaps due to turning operation. The INCISE gives a lower PCO rate but with some side effects. All impacts of the IOL design will be discuss.
