No. The first Laser did not even exist until mid-1960, so they were definitely not in surgical use in 1963-1966. Even the Soviets did not develop Radial Kertotomy surgery until 1974. RK uses a physical scalpel to make small radial incisions around the iris, and the scarring that occurs during healing causes the eyeball to shrink and warp the lens.
