Dear Editor,
During cryoextraction of the lens, the corneal endothelium is protected by lifting the cornea forwards by traction on the central corneal suture or the use of a cryoadaptor, and the iris is protected by retracting it with an iris retractor or a cellulose-sponge swab.
For performing these manoeuvres the help of an assistant surgeon is required.
While working alone, these moves can be executed single handed. with the help of this modified iris retractor.
It is a curved loop made of a 28G nonmaleable stainless steel wire. This is mounted in a hollow 20G stainless steel tube, which is fitted to a thimble instead of a handle.
It may be made for right or left hand use as per individual habits. The size of the thimble may be varied (nos. 6, 7, 8 etc.), according to the size of one's ring finger. It costs less than Rs.5/-.
METHOD OF USE:
The cornea is lifted forward by traction on the central corneal suture with suture forceps held between the thumb and index finger. The iris retractor, worn on the ring finger of the same hand, retracts the iris. All fluid in the anterior chamber is mopped. The cryoprobe, held in the other hand, is applied to the upper part of the anterior surface of the lens, and the gas-pedal is pressed. As the lens is lifted out the retractor is withdrawn and corneal suture is released. The suture forceps pull the other preplaced sutures into place to secure the section.
