“…Subsequently, hydrophilic or hydrophobic acrylate polymer with a higher refractive index was developed as the second generation IOL materials, which was foldable and alleviated large cornea incision during the surgery [ [19] , [20] , [21] ]. But, despite all these, the current IOLs are still too stiff to deform with ciliary muscle movements, resulting in fixed focal length and lack the ability to adjust focus for different distances [ 22 , 23 ]. Thus, appropriate IOL materials that can dynamically adjust to ciliary muscle movements are on great demand.…”
