Abstract

Our preferred technique of nucleus delivery is visco expression. The advantage in visco expression is that endothelium remains coated with visco at all the times, the anterior chamber remains formed and does not collapse. For beginners, it is least traumatic to endothelium.

The nucleus is tumbled upside down, and is then gently brought into the anterior chamber.

The single most important requirement for visco expression technique is an adequate and well dissected tunnel.

Visco is injected under the prolapsed nucleus, on both the sides, and to coat the endothelium.

Increase the pressure on the opposite side of the nucleus, and as you withdraw the cannula, depress the posterior wall of the tunnel gently.

The nucleus is to be engaged in the tunnel. Once the nucleus engages in the tunnel, inflate the AC and keep on giving intermittent pressure on the posterior wall. The nucleus will float out smoothly.
