What is it about?
A patient underwent pars plana vitrectomy and secondary intraocular lens implantation with a scleral fixation Carlevale lens. Opacification of the lens, without any surface deposits, was observed. The lens was transparent again the next day. An in vitro experimental test demonstrated that the material of the lens is vulnerable to thermic shock, developing an opacification which resolves with temperature stabilization.

Why is it important?
This is the first report of transient opacification of a Carlevale lens. It is relevant since it highlights that it is not necessary to proceed to intraocular lens explantation, since it is likely that the lens will return transparent within hours after surgery.
Perspectives
It is interesting to know the behaviour of the polymers composing intraocular lenses when exposed to thermic shock. This may happen especially when the lens is delivered to the operating theatre shortly before the implantation.
