The eye can be examined with relative ease as to both its function and its structure. A functional assessment 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 evaluated in several ways. The patient might be asked to recognize illuminated letter or items of differing sizes on what is called the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In specific diseases, particularly in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it needs to be well kept in mind that a patient with an eye problem may have other issues too. Often other physical conditions are main and impact the eye as a consequence. The appearance of the eye can signal the patient and the physician to difficulties in some disturbances of other parts of the body even prior to other signs present themselves.
One's reliance on sight is emphasized when one deals with a temporary or possible long-term loss of this important sense. When restorative procedures are sought, certain kinds of vision correction such as contact lenses or eyeglasses are recommended.
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 factor, advanced surgeries were established to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgery is another form of vision correction. The only distinction is that with this type of surgical treatment, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently changed. This can be done using an "excimer laser."
The main purpose of this surgery is to develop 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, permitting much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to understand. Probably, the main factor why this type of eye surgical treatment has ended up being well accepted is because many of its cases had been successful.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:

Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not constantly be the perfect eye surgical treatment the way many people view it
Conversely, the assessment of the structural part of the eye might be made in several ways. It must be well kept in mind that a patient with an eye problem may have other issues. Frequently other physical conditions are main and affect the eye as a effect. The appearance of the eye can notify the patient and the doctor to problems in some disturbances of other parts of the body even prior to other symptoms provide themselves.
