First, it can be cured by drugs or other non-surgical treatments.
Older people often see some advertisements from various authoritative newspapers or radio and television channels, often promoting the excavation of the motherland’s medical treasures and precious Chinese medicine to make a variety of strange drugs, an important feature of these drugs is to ensure rapid improvement after the use of drugs, often advertised as having more users, good use, non-toxic side effects, to adhere to the drug, etc., many older people because of fear of surgery and choose to spend a lot of money on these so-called drugs But the result is worryingly often not cured, the original disease is aggravated, to the hospital eye examination has often delayed the best treatment time.
Second, cataracts have to be mature before they can be done.
This was the view when there was a lack of clear surgical microscope thirty years ago. With the progress of technology and improvement of surgical techniques, early surgery has better results. Older people are paying more and more attention to the quality of life. To wait until the cataract is mature before surgery, the surgical incision will increase, the damage will be heavy, and the recovery will be poor.
Third, cataract surgery needs to be done only when your vision drops below 0.3 or 0.5.
In fact, checking the vision chart only represents part of our visual function. A perfect vision also includes good color vision, contrast sensitivity, aberration, etc. Contrast sensitivity is the ability to distinguish grayscale. In cataract patients, even though they have good visual acuity of 0.6-0.8 or even 1.0, they always feel blurred and have a plastic film or a wipeable eye droplet in front of their eyes. These are all signs of decreased contrast sensitivity. This is also a major reason why elderly people often fall. Therefore, cataract surgery cannot be based on “vision” in the vision chart.
The more expensive IOLs you choose for cataract surgery, the better your vision will be after surgery.
The choice of IOL is not simply based on price, but also on the condition of your eyes, your economic status and your daily needs.
1.Hard lens is inexpensive and can basically meet the needs of regaining sight after cataract surgery, the disadvantage is large incision and long recovery time, mostly used for handicap surgery.
2.Ordinary folding lens: small surgical incision, quick recovery, not equipped with other characteristics.
3.Aspheric folding IOL: significantly improve the imaging quality, especially improve the night, dark light and peripheral vision imaging quality.
4.Multifocal IOL: For the elderly, it can make them see clearly at near, middle and far, and far away. Also small surgical incision, fast recovery, and higher quality of vision.
5.Astigmatism IOL: For patients with corneal astigmatism, this IOL can be chosen when doing cataract, which can effectively correct astigmatism, high visual quality, small surgical incision and fast recovery.
Patients should choose according to their own conditions and needs, not just the price.
