—Supplemental laser photocoagulation to wall off areas of retinal detachment or to surround new or inadequately treated retinal breaks in the early postoperative period after vitreoretinal surgery is being used in certain cases of proliferative vitreoretinopathy (PVR).1,2 A biconcave contact lens for laser photocoagulation in gas-filled phakic eyes recently has been described but is not suitable for treatment of the peripheral retina.3We used the panfunduscope lens (Rodenstock Type Th) with a 200- or 500-μm spot size for laser photocoagulation of the peripheral retina four to 24 hours after supplemental fluid-gas exchange through a slit-lamp laser system in gas-filled aphakic or pseudophakic eyes in an aphakic patient with a giant tear, two aphakic patients with PVR, one patient with an anterior chamber intraocular lens and PVR, and one patient with a posterior chamber intraocular lens and PVR. The cornea was sufficiently clear to perform the
