Desiccation cataract is a common complication of posterior vitrectomy. Indeed, the contact between internal gas tamponade and posterior crystalloid can cause early posterior subcapsular cataract occurring in the twenty-four hours, also known as fern leaf-like cataract. It is caused by dehydration of the posterior layers of the crystalline lens or by a block in the metabolic exchanges from both sides of the posterior crystalloid.
