Technique of lamellar scleral resection.

THE purpose of this paper is to describe certain points in the technique of lamellar scleral resection which I think help in its efficient performance and shorten the time spent upon it. Particular mention is made of the scleral marker, the suture-retention coil, and the suture-tying forceps, new instruments which I have designed to assist in the orderly conduct of the operation. The time taken for a half-circumference resection of a scleral strip 28 mm. long is 45-55 minutes. The resection of a strip 45 mm. long which necessitated the division of three extra-ocular muscles for adequate exposure took 73 minutes.
