The eye can be examined with relative ease regarding both its function and its structure. A practical evaluation includes the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye may be tested in several methods. The patient may be asked to identify illuminated letter or things of differing sizes on what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in a number of ways. Tension within the eyeball is measured by a "tonometer." In particular diseases, particularly in glaucoma, the tension in the eyeball is increased markedly.
It ought to be well kept in mind that a patient with an eye problem may have other problems. Typically other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can alert the doctor and the client to difficulties in some disruptions of other parts of the body even before other symptoms provide themselves.
One's reliance on sight is emphasized when one deals with a temporary or possible irreversible loss of this important sense. For this reason, when corrective procedures are looked for, certain kinds of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some individuals are troubled with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgical treatment is another type of vision correction. The only distinction is that with this kind of surgical treatment, one's vision is fixed completely.
With LASIK eye surgery, the refractive errors in the cornea are permanently transformed. This can be done utilizing an "excimer laser."
The primary function of this surgical treatment is to create a threadlike, rounded "flap" in the cornea utilizing a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling better the eye to direct more light into the retina.
