Cataract and glaucoma are the most common eye diseases, and not only the number of people suffering from them is high, people have more questions and misconceptions. Although the weather was hot, readers from various main urban areas such as Jiefangbei, Nanping, Beibei and Jiangbei came to the site early and were still not satisfied after listening to the lecture, surrounding the experts who were slow to leave.
Cataracts are 60% of the eye diseases of the elderly How common are cataracts? Director Yuan Rong Di introduced that among the elderly over 60 years old, 60% of the patients with eye diseases are cataracts. If there are shadows in front of the eyes, blurred and declining vision, or photophobia, blurred vision under strong light, monocular diplopia or polyopia, or even sudden improvement of presbyopia, they are all typical symptoms of cataracts. However, many people will ignore these eye changes, and it is recommended to have regular checkups and timely consultation.
Nowadays, the market is overwhelmed with products for cataracts, but clinical observation shows that so far no drug can really prevent and treat cataracts, “Surgery is the only way to treat them, instead of spending money on drugs that have no effect, it is better to use the money spent on buying drugs to do surgery and choose a good IOL.”
It is important to choose the right time to have surgery Many patients wait until the cataract is mature before having surgery, not knowing that this will not only reduce the quality of life, but also increase the risk of glaucoma and the incidence of surgical complications. Director Yuan Rong Di pointed out that usually cataract patients can have surgery when their corrected visual acuity is lower than 0.4, but if there are other pathologies in the eye, such as glaucoma and diabetic retinopathy, cataract surgery should also be done earlier.
To perform cataract surgery, patients need to choose an IOL, but there are many types of crystals and prices vary greatly, how to choose? Yuan Rong Di introduced that the key is to choose the right one for you. For example, aspheric IOLs have higher quality of night vision; adjustable IOLs can achieve better near and far vision, but the long-term effect is not good; and multifocal IOLs can also achieve better near and far vision, which is especially suitable for the elderly who like to read and can rejuvenate their vision, however, glare may be produced at night, so people who often drive should not choose; and yellow IOLs are added with UV absorbers to block UV light, which can reduce the impact on the eyes. The yellow IOL is added with UV absorbers to block UV light, which can reduce the light damage to the macula.
Glaucoma patients Don’t drink too much water at once After the lecture on cataract-related knowledge, it was almost noon, but none of the audience present left and asked the experts to continue the lecture on glaucoma knowledge. “Glaucoma is a disease of optic nerve damage caused by elevated eye pressure, and its incidence has been particularly high recently due to the hot weather and poor sleep quality, which can lead to blindness if not treated in time.” Director Yuan Rong Di continues to patiently explain that genetics, eye trauma, inflammation, bleeding, tumors, and mood swings are all causes of glaucoma. When you have symptoms such as eye pain, eye redness, vision loss, ipsilateral headache, nausea, vomiting, sweating, or when you look at incandescent lights, colored halos or rainbow vision like rainbows after rain, beware of glaucoma.
Since glaucoma damage to vision is irreversible, it is important to take medication on time, have regular checkups, avoid mood swings; don’t drink too much water in a short period of time; avoid staying in dark rooms for too long, don’t read in dark light; it is best not to wear high collars, tight collars and tight clothes, and not to wear tight belts; ensure sleep, and avoid excessive mental and physical work.
