Retina transplantation is not yet possible in clinical practice and is still in the research phase. Retinal transplantation is one of the current directions in the development of ophthalmic technology, but there is no precedent of successful retinal transplantation in clinical work because the structure of the retina is too delicate. Many diseases in ophthalmology are related to the retina, such as macular degeneration, retinal detachment, retinitis pigmentosa, etc. Moreover, the structure of the retina is very delicate and its function is very complicated, so it is usually difficult to restore vision completely through treatment if the retina is damaged in a relatively serious way. Patients with retinal damage can experience significant vision loss. It is recommended that patients with retinopathy seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment to improve their vision.
