Last May I had cataract surgery on both eyes, and in order to minimise the possibility of complications, I chose single-vision IOLs (Tecnis silicone).
But despite this, I've suffered terribly from glare and halos, and despite what the surgeon said, I haven't neuroadapted at all. His solution was to prescribe Pilocarpine eye drops to constrict the pupils, and although they were very effective, they had three disadvantages: (1) they gave me 'brow ache', (2) the effect wasn't long-lasting and worst of all, (3) they contricted my pupil way down to pinhead size, meaning that my night vision was almost gone.
Also, I've read that if you use them for long enough, the pupil constriction is permanent, making eye examinations and other surgical procedures difficult (the surgeon never told me THAT).
And so I asked my general doc to try me on Alphagan, and this has been much more successful: it constricts the pupil just enough to take away the glare, and its effects last longer. Unfortunately, I'm an asthmatic, and suddenly noticed I was having far more attacks. Sure enough, I looked up Alphagan, and found that asthmatics shouldn't take it, as it increases attacks.
So to my question: are there other pupil-constricting drugs out there I could try? A glaucoma website I visited lists quite a few drugs with a pupil-constricting effect, but I'm not sure if people without glaucoma can take them.
Also, I did come across a research paper that said the constricting effect of Pilocarpine is proportional to its strength, and did try diluting mine without much success - but that was a very amateur attempt involving salt water, so maybe that's why it didn't work. Has anyone had success by diluting Pilocarpine? Thanks.
Glare and haloes. What is the diagnosis? This sounds like dysphotopsia. If it's dysphotopsia and you haven't neuroadapted, then surgery is the cure. The IOL needs to be repositioned by reverse optic capture. This has been well documented by Dr. Masket in Los Angeles, CA and several studies. Ironically, the diagnosis is confirmed with dilation of the pupil...symptoms will vanish. The first place to start is with a good second opinion with an ophthalmologist.
