Any surgery carries risks, and cataract surgery is no exception. However, many elderly people have mature cataracts that require prompt surgical treatment. If not addressed timely, it can lead to blindness or even cause secondary glaucoma, leading to symptoms such as eye pain, headaches, nausea, and vomiting.

In some advanced cases, it can lead to neovascular glaucoma, making it difficult to control intraocular pressure. Cataracts are a vision-impairing disease caused by the clouding of the lens, which is an important optical component in the human eyeball. Normally, the lens is transparent. In elderly people, the lens proteins often degenerate and age, leading to cloudiness and various degrees of vision impairment. It is advisable for those with cataracts to seek prompt ophthalmologic care and, if necessary, undergo cataract removal surgery. Complications and sequelae from cataract surgery may include postoperative infection, shallow anterior chamber, corneal edema, explosive bleeding, macular edema, and more.
