Eat your spinach!
Carol- you might already be familiar with this, but if not - if you want to check out any research on anything medical, go to
here to access PubMed and Medline databases.
For the lens implant/allergy search, use search terms like "intraocular lens implants" or IOL, and "allergy", "reaction" or similar terms.
Folks are right-cataract surgery is quicker than a haircut these days, but it's still surgery, and any surgery has inherent risks.
We'll all get cataracts if we live long enough. A word about sunglasses- wear good ones! The cheap crappy ones, without adequate UV protection, can cause more damage to your eyes than not wearing any sunglasses at all. Your pupils dilate behind the dark eyeglass lens, and the dangerous "UV rays" (say that in quotation marks, like Dr. Evil) get in there and cause havoc to your lenses and retinae. Or so I've heard.
Also, if and when the time comes, you're a Canuckistani now, right? Get it done here. Cheaper, probably, and you might get to have your surgery performed by the well-known and highly respected Newfoundland Ophthalmologist, "Eye's the Bye".
Also also - see an ophthalmologist as well as the optometrist.
Here's looking at you, kid.
