As cataract surgery completely removes the effected eye’s natural lens and replaces it with an artificial intraocular lens (IOL), there is no way that cataracts can come back.
If your vision was back to normal following surgery, but has become increasingly cloudy over time, this doesn’t mean that your cataracts have come back. In this instance, it’s likely that the membrane behind the lens has become misty and thicker; this is known as posterior capsular opacification (PCO). Should this be the case, don’t worry, it’s a fairly common occurrence and can be easily treated.
The most important thing to remember, should you experience PCO, is that your cataracts haven’t come back, and PCO can be dealt with very easily with a procedure known as YAG Laser Capsulotomy which is completely painless and, similarly to cataract surgery, typically takes around 5-10 minutes to be completed.
