Myopia should not do surgery, how old can do?

There is a saying that: Please forgive every one does not say hello myopia, We are not high cold, just a little fuzzy ~ ~ As a senior myopia, small series is also deeply hurt ~ ~

Summer came, do not want to let their eyes and this million wood Jing Xiu the world between the thick lenses? Want to remove glasses and do not know whether they are suitable for surgery, surgery will have what sequela? Today, let’s follow Professor Eye Li Ying wanted of the Peking Union Hospital to learn about The WHO is suitable for surgery and what kind of surgery is appropriate.

Correction methods of patients with different myopia degree

patients under 18 years of age (except in special cases) are not recommended for surgery , because the degree of myopia is relatively unstable, the recommended choice of wearing glasses, and regular review, according to the change in degrees to replace.

correction means a lot for adults , such as in addition to wearing frame glasses, contact lenses, wear night plastic mirror, as well as through corneal laser surgery to correct myopia and other refractive errors. depending on the actual situation, there are several choices :

for people with low myopia who do not have special career requirements and life requirements , you can choose to wear frame glasses or night-wearing plastic mirrors. Because glasses wear easy to change, even a very small degree changes are easier to adjust.

for people who are not willing to wear glasses or have special job and life needs, low, middle, and high myopia , my advice is to consider corneal laser surgery.

for patients with high myopia or hyper-high myopia (above 1000 degrees) and those who are not able to do laser surgery because of corneal conditions , there are few options available. These patients would most like to wear no glasses and need treatment. The patients with high myopia have good glasses because of their degrees. The degree is low, although the glasses are lighter, but can not see clearly, the degree is enough, although see clearly, but the glasses are very heavy, see the effect is not good. For this type of person, it can be corrected by the intraocular refractive lens implantation, which plays an important role in corneal biomechanics and corneal thickness protection.

Comparison of different correction methods

At present, there are two major types of corneal laser surgery: Corneal surface Surgery and corneal matrix surgery . The former represents Lasek and TPRK (all excimer lasers, or all lasers), while the latter represents LASIK, F-lasik (half femtosecond) and smile (all femtosecond lasers).

Corneal surface Surgery can treat low, moderate myopia. It does not need to make corneal flaps, especially for people with special hedges. But because of postoperative pain and recovery time is relatively long, visual acuity recovery is slow, and a few patients because the cornea appears cloudy and affect the sharpness of vision, often out of contact with more UV people do not recommend surface surgery; acne, high intraocular pressure, hormone-sensitive people are not suitable for surface surgery;

Corneal stroma Flap operation

1.LASIK and F-lasikcan treat low, medium and high myopia. Postoperative visual acuity recovery is fast, comfort is good, but because of the presence of corneal flap, the eye if the impact of external forces may cause corneal flap-related complications, and because of large incision, dry eye duration longer;

2,SMILE is currently the most advanced laser surgery, can treat low, medium and high myopia. It has minimally invasive incision, no corneal flap, fast postoperative vision recovery, good comfort, light dry eye and short duration, and can avoid the risk of corneal flap and corneal opacity. But the operation cost is high, to the patient corneal thickness has certain request, at present Ultra high myopia is not suitable for this kind of operation, simultaneously also requires the patient’s high cooperation.

Any refractive surgery will have a certain risk and unpredictability. Patients specifically choose which corrective method or to according to the patient’s personal situation and actual needs to choose.

The Cornea Laser Surgery , although very precise and safe, has a certain amount of damage to the cornea tissue. Posterior chamber intraocular lens implantation (ICL or PRL) can be used to correct high levels of myopia, but after all, the lens implantation into the eye, there is a certain risk. Therefore, regardless of which kind of surgery chooses, everybody must consider your personal needs and the physical condition comprehensively, with the doctor after the comprehensive exchange chooses.

Who’s not good for refractive surgery?

1. People who have systemic diseases, especially those with immune systems, are unable to do so.

2, the eye has the activity inflammation, affects the eyesight the cataract, the serious glaucoma or has the retinal disease not to carry on the operation.

3, the cone of the cornea or the inclination of the cone, the cornea is thin and anterior convex, is also unable to operate.

Regarding the operation, the patient has the misunderstanding

I also encountered in the work of some patients, through the examination, their own conditions are not very good, or even found some problems, the physician advised patients to suspend or not laser surgery, but patients do not understand, but also run around the hospital counseling. In fact, from a physician’s point of view: Physicians do not recommend surgery must be for the patient safety angle. The surgery is short, but the physician’s job is to maximize the benefits and safety of the patient . If the operation may cause serious adverse consequences to the patient, this risk must not take. So advise these patients, do not be forced to operate, look at the long-term some . Some patients who are not suitable for laser surgery can also opt for refractive crystal implantation and other other means .

Some patients believe that refractive intraocular lens implantation is better than laser surgery, even if their own degree is not high, but also require intraocular lens surgery. patients with a general degree exceeding 1000 degrees, corneal thickness or corneal curvature abnormalities may consider intraocular lens surgery. but less than 1000 degrees , corneal condition allowed , choosing to do laser surgery is good, or better. because intraocular lens implantation before, Postoperative examination is more complex and requires long-term follow-up (generally 3-6 months).

doctors and patients are starting from expect an optimal outcome after surgery . However, the differences in individual reactions and the unpredictability of instruments may lead to unexpected events, which are not likely to affect the subjective desires of the people. If there is a problem, the doctor will find a way to solve it, and the patient should fully understand and cooperate with the doctor. Mutual cooperation and trust between doctors and patients will be more beneficial to postoperative recovery .
