Treatment Solutions for Common Visual Disorders

Common sight disorders, ie longitudinal and short-sighted, are diagnosed by means of a complete eye examination. Test in which the doctor uses a range of medical devices to check the safety of the essential parts of the eye, through which you can relate the image of things we see to the brain. These include: the cornea of ​​the eye, the lens of the eye, the retina and the optic nerve.
After checking the state of these parts of the eye, visual abilities are measured by evaluating the "state of refraction" of each eye. As a result, the doctor gives his opinion to correct the eye defect responsible for blurred vision.

– Corrective correction
The treatment proposed by the doctor often consists of "corrective lenses", used in the form of glbades having different strengths than those observed during the eye scan, whether in length or myopia. In case of a disorder requiring treatment without glbades, such as white cataract, corneal disorders or retinal disorders, the doctor will recommend what is appropriate for them as a medical treatment likely to avoid the use corrective lenses or Do not sing
The lens therapy, for long or short vision, aims to help focus the retina through the use of corrective lenses for glbades. Although the treatment of vision defects has developed steadily over the last three decades, "glbades" are still the basis and are the most common in the treatment of vision defects. "Contact lenses" are still widespread and provide a convenient treatment solution for many people. In exchange for "glbades" and "contact lenses", there is a surgical means of treating vision defects. The medium that started with the "scalpel" has evolved dramatically to different surgical techniques using the "laser".

– Palace and welfare
In cases of myopia, the image of the visual object is confused, so that the focus of visible light falls in front of or before reaching the surface of the retina. The defect is often a lack of curvature of the cornea or the shape of the eyeball itself, that is, when the axis of the eyeball is long. In these cases, there is no problem seeing nearby objects when reading or writing, but the problem is to see the remote objects. As an illustration, the length of the axis of the eye, from the cornea to the retina, is about 4.2 centimeters (2 centimeters), which allows the lens to capture the light beam of the eye. visible image directly in the retina, which allows the retina to transmit a sharp image seen by the brain.
In cases of hyperopia, it is difficult to see nearby objects clearly, especially because of the low flexibility of the eyepiece and the inability of the lens to see the requirements of nearby objects. Thus, the image of the visible object is deformed, so that the focus of light behind or behind the surface of the retina disappears.
There are preventable cases, but the majority of common cases of myopia or lack of a consistent method of interest and agreed between physicians to prevent infection. Therefore, treatment with visual correction using glbades or contact lenses is the most common treatment in both cases. The purpose of the lenses is to balance the curvature of the cornea or the excessive length of the eye in case of myopia, and the lenses in case of long vision to facilitate the collection of the image on the retina and not after. Surgical treatment of myopia aims to improve the concentration of the eye by flattening or reshaping the central part of the cornea. It can also be a surgical treatment of the length of the view.

– Various objectives
On the side of the glbades, there are bifocal and triangular lenses, as well as progressive lenses that correct the near and far vision capabilities, as well as reading lenses to illustrate the near.
Contact lenses have undergone many developments over the past decades and started with solid, then soft, then single-use lenses. Since there are still cases requiring solid lenses, some of them have an air permeability capability that allows them to be worn longer. The beginnings of contact lenses were intended for the treatment of myopia and the inability to clearly see distant objects, and developed into types for correcting reduced, ie bifocal, vision. In case of shortness of breath and foresight, treatment solutions are available using contact lenses. One of these remedies is eye correction, commonly used to view distant objects, or "dominant eye," while using contact lenses for near vision in "non-traditional" eyes. It is true that some people may have difficulty adapting to this therapeutic solution because of the loss of 3D vision capability, but others may find a solution to the use of glbades close to contact lenses. Another therapeutic solution is to wear bifocal contact lenses in the unconventional eye and to wear contact lenses to see distant objects in the dominant eye. Then we can use the eyes to see distant objects and use an eye to see the objects nearby.

– Surgical treatments
Surgical treatment of refractive eye disorders primarily involves the treatment of myopia cases, but there are also surgical interventions for the treatment of myopia. These surgical treatments are intended to reshape the curvature of the cornea, a transparent eye that runs through the light of the things we see. Refractive surgery techniques include LASIK, LASIK and other types of surgical techniques of the cornea.
LASIK, or "laser-badisted corneal correction," is a form of surgery aimed primarily at improving the sighting abilities of people with longitudinal shape or astigmatism by changing the shape of the cornea allowing light to penetrate the eye. The eye differently, thereby correcting the patient's lack of vision. Corneal corneal correction is performed by laser. In the first step, the surgeon uses a microchromic to remove a very thin semicircular layer from the surface of the cornea while retaining a small portion of the layer that has been scraped to make a cornea. A more recent method instead of a micro-current is a femtosecond laser device. Then, in a second step, the ophthalmologist uses the laser to remove some of the inner tissue of the cornea, layers of the center of the cornea, to accentuate its curved and prominent shape. The amount of corneal tissue removal thickness is evaluated by type and degree of visual impairment. In the third step, the superficial layer of the cornea returned to its natural position to be welded without surgical stitches. The surgery itself is painless and lasts only 15 to 30 minutes. Most patients resume normal activities within two days of the end of surgery. It is important that the patient relaxes the eyes and takes into account the fact that he does not come into contact with strange substances such as shampoo, face cream and makeup after the LASIK process in the eyes, this which means that you should not wash your hair or even wash with hot water (because of the steam). Sports where friction with the garland up to a month. Other activities to avoid include swimming and driving for a week after surgery.
LASEK, or laser-badisted laser cut, is another form of surgery that aims primarily to improve vision. In this process, unlike the Lasik method, the surgeon instead of forming a flap in the cornea (a very thin semicircular layer of the cornea surface), as in the Lasik process, forms only one flap in the thin protective lining of the cornea. The surgeon uses the laser to reshape the outer layers of the cornea to make it more tilted and less polarized. Then, after completing this step, you restore the epithelial lining of the cornea. For easy recovery, you can apply the contact lens bandage several days after the procedure. After three to six days, the patient regains his normal visual abilities and can take up to a month to reach the desired vision goal.
This type of correction is suitable for various ocular refraction problems, including myopia, longitudinal movements and astigmatism. It is an ideal surgical solution for patients with thin corneas or people who perform activities involving a risk of facial injury, such as athletes and others. Some patients may experience mild tingling or even moderate pain early in their recovery. Some possible complications that may occur after surgery for refractive fractures are either less correct than required, but more correct than for the underlying vision problem: complications such as a halo vision or a radioactive star around the lights, a double vision or dry skin, or microbial infections, aspects discussed with the attending physician.
