The Intraocular Lens (IOL) Eye Model dramatically demonstrates how vision is re-gained after removal of a cataract. The six (6) inter-changeable lenses simulate IOL and Toric implants of clear posterior capsule, cloudy capsule, and post YAG posterior capsulotomy.
The model also shows a cross section of the eye in three layers; the retina, choroid, and sclera with veins and arteries, including central retinal. Measures 3.75" in diameter, and is mounted on a white, opaque plastic base. It is realistically colored and textured and the cornea, optic nerve, and insertion of muscle are shown.
