I had a vitrectomy with retinal membrane peeling in January. The operation caused cataract growth in the operated eye (right eye). I now am having a cataract operation. The pre-operation instructions were to discontinue taking supplements of vitamins A, D, E, and K two weeks before the operation. I believe this is for all cataract surgery patients. (I am having the operation done at the Wilmer Eye Institute of Johns Hopkins.) In an email, I asked the surgeon why, and he replied that these vitamins can cause bleeding. He is talking about high dose supplements, for example 400 I.U. of vitamin E.
I can understand how high doses of vitamin E might cause a decreased ability to clot, but I cannot understand the proscription against taking the other vitamins. In fact, my understanding is that even the stopping of taking warfarin before cataract surgery is somewhat controversial. There’s a section in my ig booklet that contains a table listing some vitamins and minerals found in about 150 fruits and veggies. The problem is that we really don’t know the exact nutritional requirements of iguanas. I included the table so that people could get a feel for which veggies are nothing but water, and which actually contain something worth eating.
My understanding is that oranges are not particularly good for iguanas. Ever since I bought my first ig, I’ve heard that one shouldn’t offer oranges. Never got a definitive answer why, though. As for books, I pored through the books and the only one I found that mentions phosphorus at all is called “Food Values of Portions Commonly Used” by Jean A. T. Pennington. For fruits and veggies, it lists calories, water content, fat, cholesterol, protein, carbohydrates, polyunsaturated fats, saturated fatty acids, dietary fiber, vit A, vit C, vit B2, vit B6, folic acid, vit B1, niacin, vit B12, pantothenic acid, sodium calcium, magnesium, zinc, manganese, potassium, phosphorus, iron and copper. This book is $15. As I said, it’s the only one I found that lists phosphorus in veggies, which is what I wanted at the time for Ca:P ratios. I dunno the answer to the coconut question. Seems like I’ve heard somewhere that coconut shouldn’t be fed to igs, but don’t take me at my word! I may have dreamt it.
