Like any surgery, cataract surgery is also not devoid of complications. Cataract surgery sometime complicates with crystalline lens or Intra Ocular Lens drop in vitreous cavity. Theses complications need vitreous surgery with removal of crystalline lens or IOL from vitreous cavity and implantation of IOL in sulcus or scleral fixated IOL for immediate restoration of vision. In scleral fixated IOL operation, a special type of IOL having eyes in their haptics, is tied through sclera when there is inadequate support for IOL to be placed in sulcus. Long term complications of cataract surgery like thick posterior capsular opacification may need surgical membranotomy done by posterior segment surgeon.
