A thin (20-gauge) cryoprobe can be used to retreat retinal breaks without disturbing a previous scleral buckle. The fibrous sheath covering the episcleral exoplant is incised at its anterior margin, and the 20-gauge probe is introduced between the exoplant and the sclera. Angling the tip slightly permits precise treatment around the retinal break, without removing and replacing the scleral sutures securing the exoplant.
