  • Comparative analysis of five IOL optic configurations (convexo-plano, plano-convex, biconvex, meniscus, asphero-plane).

    • Main Results:

    • A table is presented, rating the performance of each optic configuration against key optical and mechanical criteria.
    • Performance metrics highlight the strengths and weaknesses of each design.
    • The analysis facilitates informed selection based on specific clinical needs.

    Conclusions:

    • The choice of IOL optic configuration significantly impacts visual quality and surgical success.
    • Ophthalmologists can use this information to select the most suitable IOL for individual patients.
    • This evaluation aids in optimizing refractive outcomes and patient satisfaction.
