Can the operation go wrong?
In a small minority of cases technical difficulties can occur during Lens Exchange surgery. The delicate structures around the natural lens within the eye sometimes break. This can make it more difficult to remove the natural lens and/or safely insert the lens implant. For example the very thin membrane behind the natural lens may rip. This is called “posterior capsule rupture”. This membrane separates the natural lens from the vitreous jelly which fills the main cavity of the eye. If this membrane breaks the vitreous jelly can move forward into the front part of the eye. Additional surgical steps are then necessary to remove this misplaced vitreous. If these events are correctly dealt with the visual outcome is still favourable in most cases. Occasionally it is safer not to insert a lens implant when these complications occur, although this may be possible at a later date. Very rarely the natural lens may fall to the back of the eye during surgery. Referral to a vitreoretinal surgeon
