The eye can be analyzed with relative ease as to both its function and its structure. A practical examination consists of the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye may be checked in a number of methods. The client may be asked to determine illuminated letter or objects 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 ways. Tension within the eyeball is measured by a "tonometer." In specific illness, particularly in glaucoma, the stress in the eyeball is increased markedly.
However, it ought to be well kept in mind that a patient with an eye problem might have other problems as well. Typically other physical conditions are main and affect the eye as a repercussion. The appearance of the eye can notify the patient and the physician to troubles in some disruptions of other parts of the body even before other signs provide themselves.
One's dependence on sight is stressed when one faces a short-lived or possible long-term loss of this important sense. Hence, when restorative steps are sought, particular forms of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to encourage reduced 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 surgery is another kind of vision correction. The only distinction is that with this kind of surgery, one's vision is remedied completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely changed. This can be done utilizing an "excimer laser."
The main purpose of this surgery is to produce a threadlike, rounded "flap" in the cornea using 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

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 method most people view it
Conversely, the examination of the structural part of the eye may be made in several ways. It should be well remembered that a client with an eye issue may have other issues. Frequently other physical conditions are primary and affect the eye as a consequence.
