Overall, RLE/Cataract surgery is very safe.
Complications rarely occur, with a serious problem such as an infection or bleeding in the eye affecting approximately 1 in 1000 patients. 1 in 100 patients may require a second operation - this could include repositioning or exchange of the lens, clearing lens fragments from the back of the eye or repairing a retinal detachment. 1 in 10 patients may develop posterior capsule opacification (PCO) - a thickened membrane behind the new lens that can develop months or years after the operation. This can cause the vision to become blurred again and may require a quick out-patient laser procedure (YAG laser capsulotomy) to restore clarity.
The experience and expertise of your surgeon is the most important factor in minimising the risk of complications during your treatment. Daniel Gore has an excellent safety record: His PCR (posterior capsular rupture) rate, the key index for safety in RLE & cataract surgery, is 0.5 %*, compared with 1.5% national average and the Royal College of Ophthalmologist's benchmark of 2.0%.
