Retinal surgeries are delicate , highly specialised procedures. They are now very effective in treating cases of severe blindness. The first retinal surgery or 'Vitrectomy" was performed in 1970. Before that most retinal pathologies would be considered incurable. Since then the sub speciality of retinal surgery has come a long way. These days we have excellent machines with which we can perform stitchless surgeries with intruments smaller than the breadth of a human hair!
