A cloudy lens is known as a cataract. There are many types of eye drops used to treat cataracts, but their effectiveness is not yet clear.
For patients with early cataracts, eye drops can be used to delay the development of the disease, including sulfur-containing agents, quinone inhibitors, aldose reductase inhibitors, proteolytic enzyme activators, vitamins and energy synergists, natural extracts and certain herbal eye drops, such as falciparin, glutathione, vitamin C and cenolint. Among them, proteolytic enzyme activators, which have the effect of preventing oxidative degeneration of the lens, cloudiness and decomposition and absorption of cloudy degenerate proteins; glutathione antioxidants, which reduce oxidative damage of the lens and prevent cloudiness of the lens.
Some patients may have the following misconception that if irritation and pain occur after ordering eye medication that it is effective. In fact, this is not true. The lens itself has no nociceptive nerves and cannot sense pain, so the symptoms of cataract patients are mostly painless and progressive vision loss. In addition, the lens itself has no blood vessels, and it is not known whether it can absorb in the drugs to improve the cloudy state of the lens. Therefore, eye drops cannot cure cataracts at the root, and surgery is mostly required.
In summary, the effectiveness of eye drops for cataracts is currently uncertain and patients may try to use them.
