Cataract is a disease that occurs in the lens inside the eye, and any clouding of the lens can be called a cataract. Many middle-aged people in their 40s and 50s are told that they have cataracts during routine physical examinations and come to our clinic in a hurry, asking nervously whether they need medication, surgery, etc. In fact, most of these people have vision higher than 0.5 or even higher. In fact, most of these people have visual acuity higher than 0.5 or even higher. In fact, when the density of the lens is increased or the clouding is mild, it is not necessary to include cataracts if it is age-appropriate and does not significantly affect vision. I always give patients the example that, just like wrinkles, all people will get cataracts as they age, only the severity is different. Generally, with systemic diseases such as diabetes, cataracts will develop faster than the average person, and the area of crystal clouding is also special, which has a great impact on vision.
When do you need surgery?
Generally speaking, vision is the main evaluation factor. When the best corrected vision is lower than 0.3 (except for other eye diseases), surgery can be considered, but of course, the patient’s own feeling and the degree of clouding must be taken into account.
All in all, cataracts do not need to be too nervous, early conservative treatment, and regular eye clinic review, so that doctors can determine whether treatment is necessary, if there is no need to use drugs, and do not blindly follow the trend of ordering drugs to avoid unnecessary trouble.
