I am an avid follower of this community and of Dr Hagan’s responses. I searched for an answer to my question but did not find anything recent. I believe Dr Hagan is not a believer in toric IOLs, and perhaps I understand a bit more now. I am 75 years old, and had cataract surgery 5 years ago and had Symphony toric IOLs implanted. I was very happy, having been -12 myopic and 2.5 D of astigmatism before IOLs. I still have good near, mid and far vision but seemingly my astigmatism has increased from OD .75D, OS .5D just after the cataract surgery to OD 1.75D. OS 1.25D presently. I do not wear glasses for anything.(Part of the increase in the right eye, I believe, is due to a scratched cornea directly in front of the pupil.) Perhaps, Dr Hagan, is this one reason why you do not recommend toric IOLs? Because astigmatism will sometimes or often change and/or increase with a person’s age after IOL implant, making the toric lens less than a perfect solution? So my questions are these: Are changes to astigmatism common after cataract surgery, just as they might be for anyone with aging? Is laser surgery an option assuming my cornea is thick enough (which I believe it is (650ish)? If laser surgery is an option, and assuming it corrects the increased astigmatism, is it possible/probable that my astigmatism might continue to worsen after the laser treatment, if the laser treatment is successful? If there are any studies on this topic on the web, I would be most grateful for a link to them. Many thanks, in advance, Dr Hagan.
PS: I know a simple option would be to have glasses made just to correct the astigmatism and keep them handy for driving (or looking at the stars).
