Calcification of intraocular lenses (IOL), although nowadays less frequent than in the past, is a well-documented complication that can still necessitate their explantation. Although mostly noted in hydrophilic materials it has been rarely reported in hydrophobic intraocular lenses. We wish to report on two unusual cases of intraocular lense (one hydrophobic and one hydrophilic with hydrophobic surface) calcification following vitrectomy and silicon oil endotamponade.
