Subsurface calcification of hydrophilic refractive multifocal intraocular lenses with a hydrophobic surface

Opacification of monofocal intraocular lenses (IOLs) of various designs and materials has been reported. Hydrophilic acrylic IOLs are more prone to opacification than hydrophobic IOLs, but IOL surface modification by hydrophobic materials may improve biocompatibility, and few opacifications of such monofocal lenses have been reported to date. However, here we describe the characteristics of opacification of hydrophilic refractive multifocal IOLs...
