corneal topography and astigmatism prevention

Posted By Michael on July 31, 1999 at 11:23:28
If the cataract eye surgeon wanted to be extra precise to where he locates his astigmatism correcting clear cornea incision, it seems like a corneal topography & the handheld keratometry & the refractive keratometry (all 3) could be important & useful.  Please enlighten us if possible.  Does corneal topography always have to be overly controversial?  Isn't it usually better to have a little more information than too little especially if one is willing & able to pay for the extra cost involved?  
Any constructive answer will be greatly appreciated.
