Cataracts are a common eye disease among the middle-aged and elderly, but with the change of time, the onset of cataracts has also changed. There are many causes of cataracts, but at present, bright light is the main cause, and data show that the longer a person’s eyes are exposed to bright light, the higher the chance of developing cataracts.
The early symptoms of cataract are vision loss, blurred vision, and decreased sensitivity and contrast. Many people think it is a refractive problem or presbyopia and blindly get glasses, but after wearing glasses for a period of time, they find that their vision does not improve significantly. The current medical advice is to consider treatment as soon as the early symptoms of cataract appear, and not to wait for complete blindness before treatment.
Cataract treatment drugs are useless and can only relieve the surface symptoms. The principle of cataract surgery is very simple, which is to remove the cloudy crystal and replace it with a clear artificial crystal.
Many people believe in seasonal restrictions on the timing of cataract surgery. Unlike traditional surgery, cataract surgery is a minimally invasive procedure under a microscope, so there is no seasonal difference and surgery is also possible in summer. For cataract patients with nuclear opacity, the strong sunlight in summer usually makes the pupil smaller, and the vision loss is often more obvious at this time, so those who are suitable for surgery should make an immediate decision.
