Yes, the recommended medication (bevacizumab) is highly effective and widely used for wet age-related macular degeneration (AMD). Although used 'off-label,' extensive studies show it is as effective as drugs specifically approved for this condition, successfully preventing vision loss and often improving sight. Alternative generic treatments include ranibizumab and aflibercept. These alternatives are specifically approved for AMD and are chemically similar, offering comparable results. The main difference is cost, as bevacizumab is much more affordable. Both options are safe and standard. I recommend discussing with your father's ophthalmologist to decide which medication best suits his medical and financial needs.
