When conventional treatments – such as medical or surgical – fail to prevent or restore vision loss, patients often experience vision impairment. Different eye conditions may cause vision impairment under the broad categories of overall blurred vision, peripheral vision loss, and central vision loss. The severity of impairment may range from mild to severe, so its implications have immediate and long-term consequences in children and adults, such as lost educational and employment opportunities, lost economic gain for individuals, families, and societies, and impaired quality of life.
