Question 1: Cataract patients: Is there an age limit for cataract surgery?
There is no age limit for cataract surgery. Cataract surgery is short and almost painless, and patients of any age can undergo surgery as long as they do not have any other serious health problems.
Question 2: Cataract patients: Can diabetic patients receive cataract surgery?
Yes. However, it is better to have a stable blood sugar of about 8 mmol/L. Because diabetic patients are in poor physical condition, they often have heavy postoperative reactions and are more prone to bleeding and infection. Those with a long history of diabetes are often accompanied by retinopathy retinopathy and those with severe retinopathy have poor recovery of vision after surgery. However, in order to facilitate further examination and treatment of retinal lesions, cataract surgery should be received early.
Question 3: Cataract patients: When is the right time to receive cataract surgery?
Many cataract patients wait until the cataract is mature and they can’t see anything before they go to the doctor for surgery. This is an old-fashioned concept, which can cause a lot of inconvenience and even irreparable damage. This can cause a lot of inconvenience and even irreversible damage, such as secondary glaucoma and disuse visual impairment.
Generally speaking, cataract patients with visual acuity less than 0.3-0.4, which affects their normal working life, should talk to the ophthalmologist about surgery, and some patients with visual acuity of 0.5 or 0.6, but with blurred vision, can also be considered for surgery. Some patients with 0.5 or 0.6 visual acuity but blurred vision can also be considered for surgery. Some patients have 0.5 visual acuity but have different contrast sensitivity, color vision, and stereoacuity.
Question 4: Cataract patients: Is cataract surgery painful?
Cataract surgery is not painful. Most patients experience only a slight pressure or discomfort in the eye because the surgeon uses a special solution to numb the patient’s eye before surgery.
Question 5: Cataract patients: If both eyes need surgery, when can I have surgery on the second eye?
Generally, surgery on the second eye can be considered about a week after surgery on the first eye. In exceptional cases, it can also be performed after 24 hours-48 hours.
Question 6: Cataract patients: Will my vision be better after the surgery?
If the main cause of vision loss is cataract, the vision is usually well recovered the day after surgery (except for patients with severe cataract), but due to individual patient differences, some patients need a process to recover their vision, which usually takes about one month.
Question 7: Cataract patients: Why do cataract patients need IOL implants?
After cataract surgery, the lens is removed or emulsified, and the human eye is missing a part, so it does not focus light.
Question 8: Do I need to rest in bed after cataract surgery?
No, bed rest is not required, as long as the eye medication is ordered according to the doctor’s prescription. Try to avoid fumes and strenuous activities. In general, the life of the elderly is not affected. Watching TV, reading newspapers and playing with computers are all allowed, but in moderation.
Question 9: Will cataract recur after surgery?
After cataract surgery, some patients may develop “posterior cataracts”, which are completely different from pre-operative cataracts. This type of cataract is completely different from preoperative cataract. Posterior cataract is caused by the clouding of the posterior capsule of the clear lens (a necessary condition for IOL implantation), which was preserved during surgery.
The treatment is simple; the effect on vision can be resolved by cutting the posterior capsule membrane with a YAG laser in an outpatient setting. It is short, painless and low risk.
