Abstract : Artificial retina is a method of electrically stimulating the remaining retinal nerve cells of patients who have lost vision by the disappearance of the photoreceptor in the retina using a microelectrode array. The array is inserted in the retina to restore the partial visual acuity of the patients. Light stimulation is transmitted to the optic nerve through the bipolar cells and retinal ganglion cells present in the eye do. The artificial retina system is inserted into the human body to convert an external light signal into an electrical image signal. To do this, packaging technology is essential for the mechanical and electric field devices to function properly in the human body. In this study, we aimed to develop a biocompatible packaging technology that can secure intraocular light permeability. After researching the candidates for packaging, we are going to share the information on the pros and cons of the researchers who perform similar studies for the evaluation method. As a result, parylene has been improved by applying a promoter with low adhesion, low mechanical strength, and high moisture absorption and it can be improved by combining with epoxy based material.
