PMMA(polymethylmethacrylate) is used for rigid IOLs and not foldable IOL. Moreover the IOL is placed in a very thin capsular bag which is devoid of any blood supply. Hence the risk of allergy to the IOL material is very very unlikely.
Thanks! I tried to pin my opthalmologist down on this but he was too vague to be reassuring
For allergy to occur the allergen should reach the blood supply which is not possible with IOL insertion.
Good luck with your cataract surgery ! Take care !
You are most welcome.
