Purpose

Study of the cumulative rate of neodymium: YAG (Nd: YAG) laser on 11520 implantations during cataract surgery with 12 hydrophilic acrylic MICS lenses and 2 different hydrophobic ones. Analysis of the influence of material and design.

Setting

Centre Ophtalmologique Iridis Albi France
 
 

Methods

Retrospective study including all patients implanted between 2004 and the end of 2023 with one of the 14 IOLs: Akreos MICS and INCISE (Bausch & Lomb), CT Asphina 509M and AT TORBI 709M (Carl Zeiss Meditec), Synthesis and Synthesis Toric (Cutting Edge), MicroSlim, Micro AY, MicroPure, Ankoris, Finevision Toric, and PODEye (BVI), Lucidis 108M/MT, and Lucidis 124M/MT (SAV-IOL). Postoperative follow-up ranges from 1 to 237 months. Cumulative rates of Nd: YAG laser frequency were calculated and defined by a propensity score, weighted Cox regression, Tuckey test, Kaplan-Meier survival analysis, and Mann-Withney test.

Results

The 1.5-year survival rate (95% confidence interval) was 100% for INCISE, PODEye, Lucidis 108M/MT (100-100); 86.7% for Akreos MICS (83-90); 96.3% for CT Asphina (95-98); 99.2% for AT TORBI (99-100); 93.7% for MicroSlim (92-96); 93.8% for Micro AY (93-95); 96% for MicroPure (95-98); 98.2% for FineVision Toric (96-100); 94.1% for Ankoris (91-97), 97% for Synthesis (93-100), 97.4% for Synthesis Toric (92-100), and 90.7% for Lucidis 124M/MT (86-96). The 11-year survival percentage was 17.5% for Akreos MICS (14-23); 33.7% for CT Asphina (29-39); 52.6% for Micro AY (50-56) and 61.4% for MicroSlim (56-68). These are 2022 data. The statistical analysis of 2023 data is ongoing and will be presented at the congress.

Conclusions

Short and long-term analysis shows that the material is not the main factor to explain the incidence rate of Nd: YAG capsulotomy. Surface treatment and industrial processes seem to have a greater influence. Incise shows very good results in reducing the incidence of Nd: YAG over time.
