Possible side effects and complications of cataract surgery today, compared with that in the past-
Problems after surgery: Problems are rare, but they can occur. These can include infection, bleeding, inflammation (i.e., pain, redness, and swelling), vision loss, corneal swelling, an itchy or sticky eye and blurry vision for a few days after the operation, aching of the eye, which generally settles down within 10-14 days, bruising of the eyelid or eye, which will heal in the normal way, and retinal detachment. With prompt medical attention, these problems can usually be treated successfully.
The most common possible complication of phacoemulsification is clouding of the lens casing that is left in the eye to support the implant. This is called "posterior capsular opacification" and begins gradually, about two years after the operation, and results in reduced vision similar to a cataract. A relatively simple laser treatment can be used to correct it.
After cataract surgery 85 per cent of people have vision good enough to drive a car. Complications are rare, but as with any surgery, a perfect result cannot be guaranteed.
