I have a white line across my eye, told it's from my cataracts. Opinion?

have glaucoma and had laser surgery to reduce pressure in both eyes after surgery I have line across my left eye now I have cataracts in both eyes but they been there for more than 10 years and I been told they were not enlarging so no need to do surgery yet, but know since I ask about this line they say it from my cataracts , I do not want any more surgery until I make sure what happen
