Orthokeratology is a mature medical technology, and it must have qualified doctors, qualified lenses, standardized and unified operation, professional after-sales service and active cooperation of patients to ensure safety and effectiveness.
Advantages:
1, which has better imaging effect than frame mirror, including stereoscopic effect. Of course, the premise is that the lens and cornea are consistent and there is no deviation.
2. It is about 75% slower than the frame mirror. This is also the biggest advantage of orthokeratology.
2, wear at night, not nearsighted during the day, eliminating the trouble of wearing glasses and reducing the burden of eye adjustment.
3. Non-surgical, non-invasive and reversible.
4. The oxygen permeability is high (FDA approved 80, China State Food and Drug Administration approved 90, Dream David XO and XOP 100, XO2 and XO2P 140, other brands don't know), which is healthier than ordinary contact lenses.
Disadvantages:
1, the price is high. Of course, I think if you use it in your heart, it may be more than five or six thousand.
2, nursing supplies are also very expensive.
3. It must be worn every day (some people wear it overnight) to achieve the best results. If you don't wear it, you will slowly return to your previous myopia.
4. Corneal sensitivity will decrease accordingly. This is the same as wearing ordinary contact lenses.
5, the first time you wear it, you will have a strong sense of foreign body.
6. The probability of corneal abrasion and infection is higher than that of arthroscopy. This can be seen under the slit lamp microscope, and the probability of occurrence is very small. As long as the situation or stop using antibiotic eye drops for a few days, you can recover. Pay more attention to hygiene at ordinary times.
In addition, orthokeratology must undergo a series of tests before wearing, because some people are not suitable to wear it, such as patients with astigmatism, keratoconus, keratitis, severe conjunctivitis, chronic conjunctivitis, sinusitis, dry eye, severe trachoma, too large pupil, too large or too small corneal curvature, and low systemic resistance (such as diabetes).
Astigmatism and keratoconus have professional lenses, not plastic lenses, which can only be worn during the day.
In your case, the left eye doesn't need matching, and the right eye only needs about 250 degrees to 2000 to 3000.
As for the choice of brand, I can't say more. However, this kind of thing still recommends you to go to a regular hospital. After all, it is a medical device that comes into contact with the eyes (you know, genuine products are different from shanzhai). If Dream David's service attitude is poor or deceptive, you come to me, and I will resign directly and put my website about Dream David (Baidu "Dream David" can see "Dream David-Home Page"). Don't be guilty, don't be afraid of ghosts knocking at the door.
Are you afraid of the closure of the optical shop upstairs?
