Lens surgery is usually done under local anaesthetic and is painless. Usually both eyes are operated on separately but in close succession, perhaps one week apart. Visual recovery is rapid: people often have near normal vision by the evening or the following day. Treatment is performed at Thornbury Private Hospital but all your pre-operative assessments and post-operative care take place at the Sheffield Vision Centre based in the Hallamshire Hospital. Laser enhancement, if required, is free, and performed at the Sheffield Vision Centre.
