It has long been a common belief that cataracts cannot be operated until they are fully mature or even invisible.
With the popularity of microsurgery, diminished vision is no longer the only indication for cataract surgery. Generally speaking, as long as cataract affects daily work and life, surgery can be considered. Some patients may have good vision on examination, but many scenes in their daily life are not as black and white as their vision chart. As long as they have symptoms such as photophobia, glare, and decreased contrast sensitivity, they can consider cataract surgery to improve their quality of life. If the cataract is delayed until it is mature or even over-mature, it will not only cause secondary glaucoma and uveitis, but also the difficulty of surgery will be greatly increased and the complications of surgery will increase accordingly.
