pain after cataract surgery

Is the actual, physical size (not vision strength) of the replacement lens implanted in cataract surgery a critical facor, or are all lenses the same physical size?    How can it be determined if the size of the implantd lens does not fit and is he cause of continuing post-surgery pain?     How unusual is it for an implanted lens failing to improve vision , near or far, except for a distance of 2 to 6 feet?  Do all implanted lenses in cataract surgery correct astygmatisms?

In general, most IOL's are about the same size and the implant itself is rarely the cause of post-op pain.  If the implant was the culprit, it would be fairly obviously out of position and even then it might not cause pain.  Your doctor can quickly rule out the implant as a source of discomfort and if so, he or she should look closely at other causes like inflammation, or keratopathy or glauocoma etc.  Regarding the vision - it is often not the implant that can cause the vision to be poor but rather other issues like corneal or retinal problems.  You could also still have astigmatism and only two implants reduce astigmatism.  Your case is more  complex than you realize and there are many things that need to be looked in addition to the IOL.
