How is cataract treated?

Recent research suggests that cataracts are associated with systemic aging, declining lens metabolism, genetic factors, ultraviolet radiation, systemic diseases, and nutritional status. So, how are cataracts treated? Let’s explore this together.

How Are Cataracts Treated?

Currently, no medication has been definitively proven effective for treating cataracts; therefore, surgical intervention remains the primary treatment modality. Pharmacological therapies are still under investigation both domestically and internationally. In some cases of early-stage cataracts, vision may improve slightly following clinical drug therapy, and disease progression may slow. The progression from early to mature cataract is typically a prolonged process; in certain instances, it may halt spontaneously at a given stage without significantly impairing visual function.

For early-stage cataracts, oral supplementation with vitamins E, C, and B₂ may be beneficial. Certain medications may also help delay disease progression. In patients with moderate cataracts, pharmacotherapy may yield modest improvements in visual acuity and lens clarity. However, once cataracts reach the mature stage, medical treatment holds no practical therapeutic value. Surgical options include: 1) phacoemulsification, and 2) extracapsular cataract extraction.

Dietary Recommendations for Cataract Patients:

Cataract patients are encouraged to consume foods rich in vitamin C, as this nutrient helps prevent cataract formation by reducing oxidative and photochemical damage to the lens. Vitamin C–rich foods include tomatoes, Chinese cabbage, onions, spinach, green beans, oranges, grapefruits, tangerines, and strawberries.

Low blood levels of vitamin E have also been linked to increased cataract risk. Reduced vitamin E levels promote oxidative reactions, leading to protein aggregation and lens opacification. Dietary sources of vitamin E include sunflower oil, vegetables, peanut oil, legumes, whole grains, liver, dark green leafy vegetables, eggs, and dairy products.

The above provides an overview of current approaches to cataract treatment. We hope this information proves helpful to you.
