What are the complications of surgery?
The most serious complications are severe bleeding inside the eye and infection inside the eye. Severe intraocular bleeding is said to occur once in 500 operations. In my experience with the current small-incision surgical method bleeding is much more rare than that. Serious infection is said to occur once for each 1,000 operations. In my own experience it is closer to once in 2,500 operations. Less dramatic complications, with no major vision loss, are said to occur in about 3% of operations.
