1. What is Eyes ......??
Mata is one of the senses of the human body is very complex to work & vision. Although its function for human life is important, but often less terperhatikan, so many diseases that attack the eyes not treated properly & causing disturbances of vision to blindness.
To prevent blindness, it is to crash each time in the eyes, consult with doctors flee langganannya. Also recommended for eyes examined each year to the doctor, together with the routine health checks in general. So, the doctor may treat early & avoid the more severe the disease for interference-interference that occurs in the eyes that can disrupt the activity to cause blindness. Routine eye examination can be performed more frequently in those with a family history of eye diseases such as high pressure eyeball (glukoma) or cataracts at a young age.
Disturbances of vision are the most commonly experienced is dim, can be a dim distant, farsighted that usually experienced by those aged above 40 years old, or a mixture of both. All kinds of dim eye on its core focus is the interference of reflection to see. Rabun can be overcome by using glass eyes or contact lenses.
Dim addition, disturbances of vision that is often experienced astigmatism, the aberration in the eye so that light emission from the 1 point 1 does not fall on the point of focus, which causes sight to become blurred. Astigmatism can be corrected with eye glass or contact lenses.
Rabun & astigmatism can also be treated with the advances in technology that can edit aberration eye surgery with the use refraktif ray laser (LASIK) by the ophthalmologist, so that people with astigmatism can dim & free from the use of glass eyes or contact lenses.
2. How to Maintain Healthy Eyes?WHEN is a lot more children who have been using since small glasses. In fact, in addition to genetic factors, eating patterns and how to read is the eye health.
Therefore, parents should be looking at nutrition and vitamins consumed, and looking at their reading habits.
Research been done by dr Vidyapati Mangunkusumo SPM, the headline Refraksi Section Faculty of Medicine, The University of Indonesia shows, from 300 school children in urban areas, 15 percent of them experienced refraksi difference. In fact, in rural areas only 11 percent.
Vidyapati that found in the work space in the eye FKUI Jakarta that is refraksi refraction. Refraksi interruption or interference will result in dim refraction, can be remote (Miopia) or near (hipermetropia).
Rabun far, according to Vidyapati, is the focus of the ball only able to see close objects, but when you see the blurred objects located far away. Miopia aberration that is generally revealed by their parents (genetic) found that many children at early school age.
The cause of dim far farraginous: can korneanya because too convex so that shadow rays are not exactly fall on the point of focus on the retina, called makula-or lens in the eye is too fat.
The main dim far is genetic. However, environmental factors can also influence, such as a lack of food nutrition and vitamins, as well as how to read is not true. The position is best to read the sitting position with disandarkan book in front of the eye-not on the table-view with the 33 cm distance from the eye.
"If, while reading the back, then there is a tendency of the work so that the only stimulate one eye damage," said Vidyapati.
Because this is interference refraksi / refraction, the improvement with the improvement of refraction. The most simple is to use glasses. Then occurred the development of bio-medical science, so there are contact lenses that can be placed on the eye.
BUT, not all people feel comfortable using glasses or contact lenses. In line with the development of improvements to the structure of organs, surgical techniques to repair the cornea is also growing. With this technique, people do not need to use glasses or contact lenses.
"Namanya refraktif surgery. Science is the science of refraction is very long. With the development of science, improvement of refraction is now done through surgery," said Vidyapati.
Surgery begins with refraktif phase structure changes as the cornea of most vital organs in the eye, called radial keratotomy (RK).
The second phase, photo refraktif keratotomy (PRK) is operative to change the form of a cornea, but with the help of excimer laser, a form of laser that does not damage the membrane of the cell boundaries. So just remove the cells from one another. There were changes in the cornea of the impact on the improvement of refraction.
Phase three is the development of the cornea changes shape through the technique of laser insitu keratomileusis (lasik). Lasik is a procedure to erase / re-established so that future cornea cornea can better deflect. Akan sharp vision again without assistance contact lenses or glasses.
Re-establishment of cornea with this level of accuracy is very high because the calculation is done with a diagnostic tool terkomputerisasi.
With the tool as a tool orbscan cornea topography-diagnose form of cornea surface-to diagnose and sywave irregularity light into the eye, then the data can be made per individual error refraksi eyes. This data became the input for the laser to form the back surface of the cornea so that the sharp vision. Lasik technique is now more attractive.
In addition to cornea surgery, to improve the refraction can also be operative with the lens, ie, with the siphon and the original lens was replaced with artificial lenses (acrylic). This is called refractive lens exchange.
All the funds are not certainly take a bit. Therefore, the cheapest way to avoid the interference refraksi is to maintain eye health. Mengonsumsi with enough nutritious food and maintain the habit to read since childhood is still
