The eye can be analyzed with relative ease as to both its function and its structure. A functional evaluation includes the capability to move in the orbit and the response of the student to light and accommodation.
The function of the eye may be evaluated in a number of methods. The patient might be asked to identify illuminated letter or objects of differing sizes on what is understood as the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in numerous ways. Tension within the eyeball is determined by a "tonometer." In specific illness, especially in glaucoma, the stress in the eyeball is increased considerably.
It ought to be well remembered that a client with an eye problem may have other problems. Typically other physical conditions are main and affect the eye as a effect. The look of the eye can inform the client and the physician to problems in some disruptions of other parts of the body even before other signs present themselves.
One's dependence on sight is highlighted when one faces a short-term or possible permanent loss of this important sense. When corrective measures are sought, specific forms of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this kind of surgical treatment, one's vision is remedied permanently.
With LASIK eye surgery, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The main purpose of this find this surgery is to create a threadlike, rounded "flap" in the cornea utilizing a blade understood 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.
Popularity vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people must know. Probably, the main reason this type of eye surgery has become well accepted is because the majority of its cases had actually achieved success.
However, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most sensitive part of the eye

Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not constantly be the ideal eye surgical treatment the method many people see it
