Cataract patients with thicker lens thickness also have better surgical results. In the process of cataract development, the cloudy lens gradually absorbs water and expands while its thickness increases. When the thickness keeps increasing, it can squeeze the intraocular tissues and lead to the obstruction of the outflow of aqueous humor, which leads to the increase of intraocular pressure and causes secondary glaucoma. Patients may experience symptoms such as eye redness, eye pain, eye swelling, and sudden vision loss. For cataract patients with thicker lens should be treated by surgery as soon as possible. Surgery removes the cloudy lens from inside the eye and implant a transparent IOL, which usually gives good results after the surgery. It is recommended that patients go to the ophthalmology department of a regular hospital for consultation and treatment as prescribed by the doctor.
