The eye can be examined with relative ease regarding both its function and its structure. A functional examination includes the capability to move in the orbit and the response of the student to light and accommodation.
The function of the eye might be tested in a number of methods. The patient may be asked to recognize illuminated letter or items of differing sizes on what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in several methods. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased markedly.
However, it needs to be well remembered that a client with an eye issue may have other problems also. Often other physical conditions are primary and affect the eye as a repercussion. The look of the eye can alert the doctor and the patient to difficulties in some disturbances of other parts of the body even prior to other signs provide themselves.
One's reliance on sight is stressed when one deals with a short-lived or possible permanent loss of this important sense. Thus, when corrective steps are sought, certain forms of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are bothered with the fact that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were developed to encourage decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Generally, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another form of vision correction. The only distinction is that with this kind of surgery, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The main function of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and Continued laser processing, the cornea is finally reformed, permitting better the eye to direct more light into the retina.
Popularity vs. Disadvantages

Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the ideal eye surgical treatment the way many people view it
Alternatively, the evaluation of the structural part of the eye might be made in several ways. It ought to be well remembered that a patient with an eye issue may have other issues. Often other physical conditions are main and impact the eye as a effect. The look of the eye can inform the doctor and the patient to problems in some disturbances of other parts of the body even before other symptoms present themselves.
Like its concrete counterpart, LASIK eye surgery is another kind of vision correction.
