Is there any scientific basis for the claim that autumn is a good time to undergo cataract surgery?

-The weather is too hot. It will be hard to recover from surgery!
- Wait until the weather is cooler. You will sweat a lot when you go out in the summer.
- The weather is getting cooler in autumn, and it’s dry and cool, which is perfect for surgery.
-Which season is best for cataract surgery?

When you have cataracts, you will feel as if a layer of fog is floating in front of your eyes, causing decreased vision, blurred vision, and even double vision, which seriously affects your quality of life.

Many elderly people consider everything very carefully. In addition to carefully selecting the lens and surgical procedure according to their needs, they also have to pick a "good day" to have the surgery, preferably a day that is neither too hot nor too cold, preferably in autumn, because it is easy to get infected in the summer and too cold in the winter to worry about the wound splitting. Is this true? Is there any scientific basis for this?

Director Tan Yongchang of the cataract department of Dongguan Aier Eye Hospital reminds:

1. Cataract surgery has become very mature and increasingly sophisticated. It can be performed all year round. There is no specific season or time requirement for cataract surgery.

2. Once cataracts are diagnosed, the doctor will make recommendations based on surgical indications. If the patient's life is affected, surgery can be considered. Do not just "delay" or "wait". Cataract surgery before vision is significantly impaired can significantly reduce the possibility of blindness and improve vision after surgery.

3. If cataracts are too mature and not treated surgically in time, the lens nucleus will sink significantly, the anterior chamber depth will increase, the iris will tremble, or some serious complications may occur, such as phacolytic glaucoma and allergic uveitis.

Principles of Cataract Surgery

There are all kinds of cataract drugs on the market, claiming to be able to treat cataracts. Cataracts occur when the protein in the lens of our eyes denatures and becomes cloudy, which cannot be cleared by drugs, causing the lens to return to a "transparent" state. The only correct way to treat cataracts is to replace the cloudy lens with a transparent artificial lens through surgery.

Key Points

Eye drops cannot reverse cataracts that have already occurred, and there is no scientific evidence that they can slow the development of cataracts. It is not recommended to use intraocular eye drops to treat cataracts.

Is cataract surgery necessary?

When it comes to "surgery", the first thing that comes to mind is the possibility of having to undergo surgery, which inevitably makes people feel afraid and therefore reluctant to undergo surgery.

As our vision requirements increase and medical technology develops, a more advanced surgical procedure - femtosecond laser-assisted cataract surgery has appeared in the public eye. It is also called "scalpel-free surgery" and uses femtosecond laser to replace the traditional scalpel to complete key steps such as incision, capsule tearing, and nuclear chopping that are manually performed in traditional phacoemulsification. The entire process is intelligent and avoids manual operation errors.

Director Tan Yongchang introduced that the surgery is minimally invasive and the entire process is completed by femtosecond laser, which is precise and knife-free. According to the preoperative design, the cloudy cataract can be split accurately, which greatly reduces the surgical trauma and allows for faster postoperative recovery. It has higher precision and controllability, and can effectively reduce the occurrence of complications. Many high-end multifunctional artificial lenses can meet the patients' high-quality eye needs. For example, after the surgery, cataracts, high myopia, presbyopia, and astigmatism can be solved at one time, which requires the accuracy of the surgical steps. Femtosecond laser-assisted cataract surgery can better guarantee the postoperative visual quality.

What should you pay attention to before cataract surgery?

Since autumn is here and the wind is blowing, if you want to have your cataract removed now, don't hesitate. So, what should you pay attention to before cataract surgery?

First of all, you need to maintain a good physical condition and avoid colds and flu, because sneezing and coughing may affect the sealing of the incision.

At the same time, blood pressure and blood sugar should be controlled within the standard range. During the preoperative period, remember to use antibacterial eye drops as prescribed by the doctor; get enough sleep and eat a reasonable diet, especially the night before the operation. Eat a reasonable diet on the day of the operation and avoid overeating or eating irritating foods.

In addition, on the day of surgery, try not to wear makeup, keep your face and hair clean, wear light and comfortable clothes, and avoid wearing high collars, pullovers, etc. Paying attention to these matters before cataract surgery and doing a good job of preoperative protection can effectively avoid adverse factors, help yourself perform the surgery better, and restore clear visual quality after surgery.
