Spanning more than 60 years of history. Menicon’s goal is to develop safe and effective contact lenses. For this purpose, the company’s R&D departments have focused for decades on developing hyper-oxygen transmissible contact-lens materials, as it is well known that this is one of the most important features for safe contact-lens wear. In 1979, the founder of Menicon, Mr. Kyoichi Tanaka, patented the first silicone hydrogel (SiH) material in the world for use in the manufacture of contact lenses.1In 2001, Menicon successfully launched the Menicon Z lens, which has the highest oxygen permeability of all gas-permeable lenses available worldwide and is the only one approved by the FDA for up to 30 days of continuous wear.

Therapeutic bandage lenses are used for certain acute and chronic ocular conditions such as corneal abrasion, recurrent corneal erosion, filamentary keratitis, post-surgical conditions, and even for ocular drug delivery.
Bandage contact lens use after photorefractive keratectomy
This study shows that SiH contact lenses can be used as an effective bandage after PRK due to the limited time requested for achieving complete corneal re-epithelialization. Asmofilcon A lenses provide faster and smoother epithelial healing in compari- son to Lotrafilcon B lenses.
