Myodisc
A myodisc or myopic disk is a corrective lens with a steep concave curvature that is fitted on the posterior surface of a carrier lens, or a high power single-vision lens specially ordered with slab-off the edge, creating a central prescription disc. These are used for correction of extremely high myopia often seen in low vision patients. Myodiscs are not a preferred lens type, but are the least expensive option among available lenses fitted for minus powers beyond -12 diopters. They are cheap to produce but cause scotoma, a ringed blind spot. As a result, most practitioners encourage using other lens styles.
