A second surgery is alaways risky as far as eye is concerned. It can cause more inflammation in the eye. As far as your surgery is concerned, the difficulty could be because of inadequate support for the lens. If the posterior capsule is not intact,(lens rests on this capsule only) then it will be difficult to place the lens. There could be adhesions between the lens and capsule which can cause more damage to the capsule and it would be difficult to explant the lens. Also the vitreous which lies behind the capsule will come forward and may cause posterior segment problems. You should discuss it with your ophthalmologist as he has examined you and knows what all problems could come in your case. Thanks.
