Why does our vision deteriorate?
The human eye has several refractive media through which the light rays from objects pass. In the end, they focus on the retina, and we get a clear image. But this is if the vision is good. When refractive disorders (myopia, hyperopia, astigmatism) are disturbed, the length of the eye does not correspond to the strength of the refracting apparatus (the cornea and lens) and the person does not clearly see.
What is myopia?
With myopia (myopia), a person poorly distinguishes objects located at a far distance. This is due to the fact that the parallel rays of light coming from objects located far away are reduced to focus in the plane in front of the retina, and not on itself, as a result of which visual acuity decreases. Most often, this is because the anteroposterior axis of the eye is too long.
To date, there are more than 20 methods of correcting myopia. However, excimer-laser vision correction is the most effective and safe of them - this is recognized by many of the world's leading ophthalmologists.
How does your vision improve after laser correction?
In the process of correction, the laser creates a new form of the cornea, the “natural lens” of our eye, as a result of which it begins to refract light rays in a different way, they focus on the retina and the previously blurry images become clear.
Laser correction can be done to absolutely everyone?
Correct vision is not recommended before the age of 18 and after 45. Such limitations are due to the fact that before the age of 18 the body is still developing and growing, including the eyeball, so the refraction of the eye can also change. And after 45 years, we warn patients that the laser correction does not insure against the appearance of presbyopia (presbyopia).
What are the contraindications?
In addition to age restrictions, contraindications to laser correction may include the presence of eye diseases such as cataracts, glaucoma, pathologies of the retina, keratoconus, and common diseases (tuberculosis, diabetes, inflammatory diseases, tumors, infections) in a patient.Laser correction is not recommended for pregnant and lactating women.
How to prepare for laser correction?
Full diagnostic examination of the visual system is necessary before carrying out laser correction. It makes it possible not only to detect refractive disorders and make an accurate diagnosis, but also to determine whether there are any contraindications to the use of the laser technique and to predict the result of a future correction.
How is the laser correction?
During correction of the Lasik method with a special device - a microkeratome, the surface layer of the cornea is bent down with a thickness of 130-150 microns, opening access to its deeper layers. Then the laser evaporates part of the cornea, the flap returns to the site and is fixed by collagen, the cornea's own substance. Suturing is not required, since the restoration of the epithelium along the edge of the flap occurs independently.
How fast is the restoration of vision after laser correction?
You will see well within a few hours after the laser correction, but the final normalization of vision will take several days.About 80% of patients start their daily activities the next day.
What are the limitations on laser correction?
Restrictions immediately after correction are minor and mainly concern hygienic procedures (swimming pool, sauna, use of cosmetics). In the future, no restrictions - no. Laser correction is a guaranteed method that does not impose any restrictions on physical and visual loads in the future. In modern ophthalmology, this procedure is the only vision recovery technology for persons experiencing maximum loads, for example, athletes.
Can the vision deteriorate after correction?
The result of the laser correction will not change with time. This fact is proved by time. After all, the correction of vision passed through multistage clinical trials, before it began to be used in ophthalmologic clinics. However, all patients who decide to conduct a laser correction, doctors warn that visual impairment is possible in the case of age-related changes in the body after 45-50 years of age and the development of age-long-sightedness (presbyopia).
