I’ve had proliferative retinopathy for about 30 years and sight loss totally in one eye. I only have a lens in one eye, I had to have the other permanently removed from my blind eye. I needed a cataract operation about 5 years back, it developed so quickly & I was struggling to see. The operation went well but I was warned that cataract surgery could cause my retinopathy to worsen & speed up progression.
It was rock & a hard place time, I could hardly see with the cataract & decided to go ahead with surgery and hope for the best. The operation was fine but I needed yag laser a few months after as my new lens clouded over and needed a special type of laser to clear a membrane that had grown over it . I’ve had a few problems with my proliferative retinopathy since & new blood vessels appearing on the edge of my macula but it is just been reviewed regularly at present.
Your surgeon will advise you on the best timing for cataract surgery. Having retinopathy doesn’t mean you can’t have cataract surgery but there are some increased risks.
