title: Intraocular gas injection in the pseudophakic patient.
abstract: Two patients underwent vitrectomy with the use of intraocular gas. In one patient the cornea decompensated because of lens-cornea contact and in the second patient a surgical technique devised to protect the cornea from lens contact was used successfully. The technique consisted of injecting a smaller gas bubble into the anterior chamber before the instillation of the posterior chamber gas.
