Treatment of cataract continues to be a terrible challenge because of the barriers as cost, lack of population awareness, shortage of trained personnel and poor surgical outcomes. Phacoemulfication is the preferred method of surgery in developed countries but manual small incision can be preferred in the developing world because of low complication rates, significantly fast, less expansive, requires less technology and shown to give similar surgical outcomes as phacoemulfication.
