To the Editor:

—I read with some interest the article by Cogan and Kuwabara "Orbital Reaction to Sponge (Ivalon) Implant," ARCH. OPHTHAL. 65:646, 1961. In the past 3 years, we have performed 32 enucleations and 3 eviscerations in which Ivalon was used as the implant.

In reviewing our results several months ago, it was found that 12 (37%) of the implants had become exposed and required either complete removal or partial excision with repeat closure, and on occasion another repeat partial excision.

Of the 3 eviscerations (Burch's type), one eroded through the cornea and also the sclera superiorly after a period of 6 months.

Of 10 plastic ball implants into Tenon's capsule, we have had no extrusions or exposures.
