Development
In 1974, Svyatoslav Fyodorov removed glass from the eye of a boy who had been in an accident. The boy, who required eyeglasses for correction of myopia caused by astigmatism, fell off his bicycle. His glasses shattered on impact, and glass particles lodged in both eyes. To save the boy's vision, Fyodorov performed an operation which consisted of making numerous radial incisions extending from the pupil to the periphery of the cornea in a pattern like the spokes of a wheel. After the glass was removed by this method and the cornea healed, Fyodorov found that the boy's visual acuity had improved significantly.
