IOL Scaffold or Intraocular lens Scaffold technique is a surgical procedure in Ophthalmology. In cases where the lens bag is ruptured and the cataract of the eye is not yet removed one can inject an artificial lens or Intraocular lens (IOL) inside the eye under the cataract. This way the IOL acts as a scaffold and prevents the cataract pieces from falling inside the eye. One can then remove the cataract pieces safely by emulsifying it with ultrasound. This technique is called IOL Scaffold and was started by Dr. Amar Agarwal from Chennai, India at Dr. Agarwal's Eye Hospital.
