Five years after implantation of three-piece hydrophobic acrylic intraocular lens (IOL) (Model: MA60AC) for traumatic cataract in a 50-year-old, a homogeneous opacification of the optic was seen [Figure 1]a. A possible mechanism for this opacification (whitening) may be a sustained mild postoperative inflammation that can alter the biomechanics, leading to an influx of water and opacification of the optic.[1],[2] | Figure 1: (a) Homogeneous opacification (whitening) of the entire optic of a hydrophobic intraocular lens.

Five years after implantation of a hydrophilic acrylic IOL in a 74-year-old, discrete white calcific deposits were seen all over the posterior surface of the optic [Figure 1]b. This was probably caused by an altered surface integrity that allowed adsorption of proteins with the deposition of calcium.[3]
