Myopia can be corrected with laser only when stabilized

Myopia can be corrected with laser only when stabilized

It is common to find children in the school period who begin to jot down information on the board and school performance begins to fall. Many parents rebuke the child, but they do not realize the problem. One day, the teacher walks through the student's wallet and perceives wrong notes in the notebook and suspects that he has myopia. Then the parents are notified and the diagnosis is confirmed by the ophthalmologist.

Myopia is due to a stretching of the eyeball by its anterior and posterior poles. That is, the myopic eye is one that has anteroposterior diameter superior to normal, so the patient has difficulty in seeing objects that are far away. The disease also arises because of increased corneal curvature, or also at the onset of cataracts, or spasms of accommodation. All of these causes an increase in refraction of the lens.

In a normal situation, the rays of light focus or converge at the level of the retina, thanks to the crystalline power of the lens. In myopic eyes, there is the anteroposterior diameter above normal, that is, they are longer. Then the light rays do not focus on the retina, but rather on it. As a result, you do not see an object well at a distance. If this object is close to the eye, normal vision is present, but if it is distant, there is a blurred vision.

It usually occurs in the child's growth phase and stabilizes at the end of youth or beginning of the phase adult, around the age of 18 years. However, there are rare cases of progressive myopia that develop even after 20 years of age. In these diagnosed patients, the correction can be through glasses, contact lenses or refractive surgery, but surgery can only be considered when myopia has been stabilized for at least one year.

There are rare cases of myopia not stabilizing, malignant calls, which evolve to high degrees of the condition. In these patients, close follow-up with your ophthalmologist should be followed closely.

For children who have not reached adulthood, it is recommended to wear glasses or contact lenses from patients who require of corrective lenses with high degrees, being adapted even in small children.

Corrective surgery is indicated after one year of stabilization, and today it is very safe, with no risks, and it is safe to do so. with excellent results, correcting up to nine degrees of disease. Laser changes the shape of the cornea and improves the way light is focused or refracted by the eye. It also reshapes the shape of the cornea and, by adjusting the laser beam, treats high degrees of myopia and the corneal disc is reinserted in its original position.

The outpatient procedure does not require hospitalization. The stitches are also dispensable by the high power of natural adherence of the cornea. Many patients report improvement in vision the day after surgery and return to their normal life in one or two days.


Stress at low levels may also increase risk of heart attack and stroke

Stress at low levels may also increase risk of heart attack and stroke

British Medical Journal . The researchers analyzed data from more than 68,000 people at the age of 35, all of whom participated in a Health Survey for England. The stress and anxiety levels of all participants were calculated and, for ten years, the authors related these rates to all causes of death among members of the group, such as heart disease, cancer and external factors.

Marijuana use can double the risk of car accidents

Marijuana use can double the risk of car accidents

New study of Columbia University , in the United States, found that marijuana use increases the occurrence of car accidents. To conclude, the researchers looked at nine studies, of which eight concluded that drivers who use marijuana are more likely to get involved in traffic accidents. The exception was because of a smaller study conducted in Thailand, but the prevalence of herb use in this study was much lower than in the other studies.
