A total of 1401 eyes received 2194 injections of Ranieyes between June 2022 and November 2023.

Non-serious adverse events (nsAEs) were observed in 26.83% of injections, with mild ocular pain and transient blurring of vision being the most common. Serious ocular adverse events were rare, occurring in 0.85% of eyes, with retinal pigment epithelial tear (RPE TEAR) being the most frequent.
