At present, despite such advanced technology, there is no cure for myopia (mainly referring to true myopia) for the time being. There are many people, especially parents, who do not believe this and always try various treatments for their children’s myopia with the intention of giving it a try, and the results are disappointing.
There have been numerous treatments for myopia over the decades, but so far they have failed to solve the underlying problem. True myopia can be said to be a kind of overdevelopment of the present, most of the eye axis becomes longer due to myopia, so think about it, such as a person grows 180CM high, want him to become shorter and shorter, not surgery, only through medicine or other methods and harmless to the person, do you think there? If there is such a method, myopia will have to be cured. Therefore, the focus of medical research now is on how to prevent myopia from deepening, rather than curing it. It is also very difficult to prevent myopia from deepening. Children wearing glasses only slow down the increase of myopia and do not prevent it from deepening, and after the age of 18 myopia will almost never deepen (but be careful to use the eyes reasonably), but astigmatism generally does not change. If you want to get glasses, try to go to a hospital with an optometrist, not an optician, and atropine dilatation is a must (for children, adults usually have small pupils).
If you want to basically deal with the deepening of myopia, most of all from the eye habits, incorrect eye habits, are the cause of deepening myopia. If you walk and run for two hours, feet tired, right, you use the computer for two hours, eyes will be tired? It is the same reason, reasonable eye habits and rest, is necessary.
At present, from Chinese medicine, Western medicine, nutrition and other aspects say that there are some methods to say that can prevent myopia deepening, but are unable to have the effect to increase to more than 20%, are below 20%, this ratio also includes the treatment of pseudomyopia, so in the range of true myopia has an extremely low effect.
The following is a method.
Natural recovery method: This method advocates correcting the child’s bad habits and achieving natural recovery of vision by strengthening daily protection. Look as far away as possible with both eyes during recess for 15 minutes twice a day. This method is effective for myopic patients who are initially found to be in a borderline state; it is not effective for myopic eyes that mostly exceed -1.00D. Myopia can become more severe as schoolwork gradually increases.
For the treatment of myopic eyes, in fact, medically known as correction, or because for myopia can not be cured at all.
Myopia correction methods are usually three.
1, lens correction: including frame glasses, corneal contact lenses;
2, corneal refractive surgery: excimer laser epithelial flap under keratomileusis (LASEK), excimer laser in situ keratomileusis (LASIK), anterior elastic layer under keratomileusis (SBK) and femtosecond laser – SBK, etc.;
3. Intraocular refractive surgery: clear lens removal, IOL implantation for crystalline eyes, etc.
It should be noted that, from the perspective of safety, simplicity, economy and practicality, the ophthalmology community believes that for most people, the preferred method of correcting myopia is still to wear frame glasses.
1, with glasses correction: is one of the most common, the most classic method.
To the regular hospital to do astigmatism, with concave lenses to correct myopia, with the right glasses, to achieve normal vision (1.0), the principle of prescription is to get the best vision of the lowest number of lenses. Contact lenses are suitable for refractive parallax, moderate to high myopia, cone corneas, or certain occupational needs. However, there are more potential complications and it is not recommended to wear them all year round.
2. Surgical correction: Suitable for patients over 18 years of age with stable prescription.
If patients are ready to choose excimer laser surgery, then the most concerned issue is the safety of the surgery.
Objectively speaking, the safety of the current excimer laser surgery is relatively high, compared with the earliest myopic radial keratotomy surgery using a diamond knife, its safety has taken a qualitative leap, after more than 20 years of extensive clinical practice fully proved this, it can be said that the laser treatment of myopia surgery in China has been relatively mature. However, the success rate of any surgery cannot be 100%, just as contact lenses are prone to infection that endangers vision, and trauma caused by ruptured frame lenses is one of the causes of blindness. The world’s most authoritative agency, the FDA, has long recognized that excimer laser treatment for myopia is safe and effective. Our physician association, the Society of Ophthalmology, also issued a statement in March of this year that excimer laser treatment for myopia is safe and effective.
Of course, good surgical equipment, skilled and experienced surgeons, and good patient cooperation are the basis for a high level of safety.
There are risks associated with any surgery, and laser myopia surgery is not completely immune to complications. The most common complication is overcorrection or undercorrection, these should be observed after a certain period of time and second surgery as appropriate; some people can have glare, that is, a light spot is seen as a light mass or halo at night, this can be due to a slight edema reaction between corneal tissues after surgery or a larger pupil at night and its edge is close to the surgical edge, gradually reduced with time after surgery; cone cornea in people with this potential or corneal LASIK is associated with corneal flap-related complications such as subflap foreign bodies, flap displacement, lysis, and increased astigmatism. Astigmatism increases, and dryness of the eyes is perceived.
Strict postoperative medication and review is an important part
Some patients have unsatisfactory results or complications after surgery because they did not follow the medication and review instructions strictly. If the eye pain is obvious, you should pay attention to distinguish between eye skin pain and eye pain, if it is the latter, you should see an ophthalmologist immediately to rule out the possibility of infection and corneal flap dislocation. If you have eye symptoms on the day of surgery, you can rest with your eyes closed and do not remove the transparent eye shield at will, and do not squeeze or rub your eyes.
The next day, the doctor will remove the transparent eye shield and check the visual acuity, cornea and refractive status, and then go for a review 3 days, 7 days, 1 month, 3 months, 6 months and 1 year after the surgery. Especially in the early postoperative period, the doctor can adjust the medication according to the results of the review, which is also an important part to ensure the success of the surgery. Patients should also be instructed to avoid going to smoky places within a week after surgery, eat less spicy and stimulating food, and not to wear makeup on the eyes to avoid having water and fine particles in the eyes. Many people regained normal vision the day after surgery, but later days but vision fluctuations, some people’s vision is gradually returned to normal, mostly two weeks more stable, the final recovery period of 3 to 6 months. after LASIK surgery, but also point with antibiotic eye solution, hormonal eye solution and promote the growth of corneal epithelium, lubrication and anti-drying eye solution, generally not more than a month. Within a month should be used less close fine vision (including watching computer, TV).
After surgery because of the change of refractive state, some people will feel the difficulty of near vision and easy fatigue in the early stage, if work and study cannot be avoided, more intervals, more blinking and more rest should be taken, and the symptoms usually disappear gradually with time. Furthermore, we should pay attention not to swim for one month, avoid diving and intense confrontational sports to avoid hitting the eye, causing eye trauma, dislocation or even loss of corneal flap. If you have glare symptoms, you should wait until the symptoms disappear before driving at night.
The risk of myopia surgery is very small, but not everyone can undergo excimer laser surgery, and the specific problem will be determined by the results of the examination at the hospital.
