To the Editor.  —My experience in a series of more than 800 consecutive cryoextractions of cataracts included only one instance of freezing injury to the cornea, followed by transient corneal edema. This is in accord with the experience of Worthen and Brubaker (Arch Ophthal79:8-9 [Jan] 1968) who found no lasting damage in more than 1,200 cryoextractions. I believe that corneal damage can be avoided by proper use of a suitably insulated cryoextractor.
