I did my first operation of an acrylic lens implant in 1953. The procedure of introducing the lower pole of lenticulus behind the lower part of the iris was easy, but the difficulty arose when the lens was released from the forceps and was to be moved into position with the upper pole behind the corresponding part of the iris.

I therefore first got prepared a single point blunt iris retractor but on using this for my next operation I noticed that this retractor could be applied at any one point only of the sphincter iridis. When lifted away it produced a festooning of the iris. So I thought of a forceps type retractor with two retraction tips.

[Figure - 1] shows the cross-action in this instrument which gives good control over the amount and width of retraction of the iris. This instrument was pre­pared to my specifications for me, by The Bombay Surgical Company, Bombay.

During the next operation of acrylic lens implant, I used this instrument which made the manouvering very easy. [Figure - 2] shows the retraction widened with the forceps opened.

The lenticulus was released from the fixation forceps, the iris was brought forward anteriorly over its upper part and released from the retractor. The sphincter immediately contracted and helped to hold the lens in situ. A little stroking with an ordinary repositor was enough to position the lens finally.

Incidentally this retractor is useful during intracapsular cataract extrac­tions. The upper part of the pupilary border of the iris can then be grasped near its upper pole and extracted with the upper pole first. This obviates any further manipulation such as tumbling and consequent disturbance of the vitreo
