    A 45-year-old man presented with com­plaints of diminish­ing vision in his right eye for 1 week. Fundus examination revealed a total retinal de­tachment with hand motion vision in that eye. The left eye was normal. He under­went pars plana vitrectomy with scleral buckle and a gas tamponade with sulfur hexa­chloride. On the first day postoperatively, the pos­terior segment examination revealed an attached retina with a 90% gas-filled eye. In addition, we observed a new-onset posterior subcapsular cata­ract, which had a ferning pattern (Fig. 1).

    On subsequent follow-up appointments over 7 days, we saw the gradual disappearance of the cataract (Fig. 2) without any intervention, which is why we call it “evanescent cataract.” The reason for the disappearance is unclear; we attribute it mainly to gas-induced oxidative stress—as the gas was absorbed the cataract vanished.
