After cataract surgery, patients will gradually recover, and the symptoms of cataract such as vision loss, blurred vision, decreased contrast sensitivity, and color vision change will gradually subside. 1. Loss of vision: Loss of vision is a common manifestation of cataract patients, usually due to the clouding of the lens interfering with the entry of light into the eye, after treatment, with the removal of the cloudy lens, the patient’s vision can be gradually restored. 2. Recovery of blurred vision: cataract patients show that they have blurred vision and feel hazy in front of their eyes, like a layer of fog, after treatment, the patient’s vision becomes clear. 3. Contrast sensitivity reduction recovery: In daily life, human eyes need to distinguish objects with clear boundaries and objects with fuzzy boundaries, and the latter distinguishing ability is called contrast sensitivity. Patients with cataract may experience a decrease in contrast sensitivity. After treatment, the contrast sensitivity is provided and patients can gradually be able to distinguish the boundaries of objects normally. 4. Recovery of color vision: The turbid lens enhances the absorption of blue light, which may make the patient insensitive to this part of the color, after treatment, the patient can gradually return to normal color vision. It is recommended that cataract patients consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
