I hope it will be useful to you, and I hope you can get early treatment and a speedy recovery.

This depends on how myopic your eyes are. The cost of doing it in Nanchang ranges from 4,000 to 10,000. Nowadays, most people perform laser correction. The actual surgical process only takes less than a minute (if you cooperate). However, a series of examinations are required before the operation, which will take some time. You can see clearly soon after the operation.

With the continuous development of science and technology, methods and means for treating and correcting refractive errors (refractive errors include myopia, hyperopia, and astigmatism) are changing with each passing day. There are surgical methods, wearing RGP, and wearing OK. Glasses, soft contact lenses, glasses, etc. Because many refractive error treatment methods have a strong sense of commercialization with the participation of many businesses. Under the commercial hype, customers are lost in the overwhelming advertising. Nowadays, surgical methods are increasingly used by younger patients with refractive errors. In particular, some businesses only promote their advantages and downplay their disadvantages. A typical example is excimer laser surgery (PRK, LASIK, PTK). Exaggerated publicity for the treatment of refractive errors, and misled by false advertising, many patients believe that this technology is omnipotent and are completely unaware of its possible sequelae and dangers.

For example, a survey by the Ophthalmology Department of a hospital affiliated to a medical university in Shanghai showed that many patients choose laser surgery simply to get rid of their dependence on glasses; some patients consider laser surgery from a cosmetic perspective. Respected and authoritative medical experts believe that performing laser surgery on normal eyes just to get rid of glasses or contact lenses is not worth the gain.

LASIK laser treatment for refractive errors was proposed in the 1990s and is now the most commonly used method. Before the operation, fundus examination, intraocular pressure measurement, A-type ultrasound, corneal topography and refraction must be performed. Then, preoperative topical anesthesia is performed, and part of the cornea of ??the eye is incised, just below the incised corneal flap. The corneal stromal layer is laser cut, and finally the cut part of the corneal flap is reset. After the operation, antibiotics and some hormonal drops are required.

So, what are the advantages and disadvantages of laser surgery in treating myopia?

Advantages of laser treatment for myopia: The effect is ideal for customers with low and moderate refractive errors. The rebound rate of myopia is low. The surgery can temporarily eliminate the need to wear glasses for a period of time.

The current problems and disadvantages of laser treatment for myopia are also very obvious: because this surgery has been around for a long time, ophthalmologists are still unable to calculate and determine its long-term effects; some patients have a long period of time after surgery. Take eye drops within a certain period of time, otherwise your eyes will become dry and uncomfortable, and some may even take eye drops for a lifetime. In addition, the following complications are prone to occur during and after the operation:

1. Corneal flap deviation from the center, corneal flap misalignment, corneal flap wrinkles, corneal interlayer debris or blood residue;

2. The laser cutting is off-center, and the keratome cuts through the cornea;

3. Life-long glare and dazzling after surgery: myopia is more common at high altitudes, and there is blur when looking at things. Halo;

4. Under-correction or over-correction: If this happens, re-operation will be required, and the effect after the re-operation is not very satisfactory;

5. Vision rebound: especially for high myopia For patients, their vision begins to decline a few years after surgery;

6. Best corrected visual acuity declines: after surgery, the vision cannot be achieved with glasses;

7. Dyslexia, dry eye, decreased corneal sensitivity, pain;

8. Irregular astigmatism: Almost all patients have varying degrees of irregular astigmatism after surgery.

9. Corneal infection, diffuse interlaminar keratitis, formation of central corneal island:

10. Peripheral corneal degeneration or scar formation, central corneal pigmentation.

Based on the above reasons, most doctors are unwilling to perform laser surgery on people with myopia, regardless of profit. Regardless of the incidence rate of the above-mentioned sequelae, if any one of the many complications falls on a patient who undergoes this surgery, it will be a lifelong regret and misfortune. Because we only have one pair of eyes, light is a priceless treasure. What’s even more dangerous is that according to strict medical regulations, a keratome can only be used on one eye. However, nowadays some hospitals or myopia treatment centers, in order to obtain high profits, reuse a keratome, as is often reported It is the same as saying that dialysis tubes in hospitals are reused. Therefore, before doing this surgery, do not listen to one-sided opinions from one party alone, but must carefully consider and weigh it repeatedly.

On the other hand, this surgery is expensive, costing several thousand yuan. We hope that patients with refractive errors will carefully weigh the pros and cons and think twice before committing.
