Voltarol Ophtha, also known as diclofenac sodium, is a non-steroidal anti-inflammatory drug (NSAID) formulated for ophthalmic use. It is primarily prescribed to treat pain, swelling, and inflammation associated with post-operative states, particularly after cataract surgery, as well as for the treatment of certain eye conditions such as seasonal allergic conjunctivitis. Voltarol Ophtha works by inhibiting the substances in the body that cause inflammation and pain, providing relief and promoting faster healing in the affected eye areas. It is typically available as eye drops and should be used under the guidance of a healthcare professional to ensure safety and effectiveness.
