This report discusses in detail the impact of COVID-19 on Ophthalmic Viscoelastic Devices (OVD) market for the year 2020 and beyond. Ophthalmic viscoelastic devices, also known as OVDs, are devices used during intraocular surgery and are primary composed of sodium hyaluronate, chondroitin sulphate, or hydroxypropyl methylcellulose. These devices protect delicate ocular structures and reduce post operational complications such as corneal edema. OVDs help maintain pressure in the anterior chamber of the eyes and prevent iris prolapse by maintaining compartmentalization of the eyes. The use of these devices significantly reduces patient recovery times. They are often used in cataract surgeries, including extracapsular and phacoemulsification surgeries.
