The eye can be analyzed with relative ease as to both its function and its structure. A functional assessment includes the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye might be evaluated in several ways. The client may be asked to recognize illuminated letter or objects of differing sizes on what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in several ways. Stress within the eyeball is determined by a "tonometer." In certain illness, particularly in glaucoma, the stress in the eyeball is increased considerably.
It should be well remembered that a client with an eye problem might have other issues. Often other physical conditions are main and affect the eye as a effect. The look of the eye can alert the patient and the doctor to problems in some disturbances of other parts of the body even prior to other symptoms provide themselves.
Consequently, one's dependence on sight is emphasized when one deals with a short-lived or possible long-term loss of this important sense. Hence, when corrective measures are sought, particular kinds of vision correction such as contact lenses or glasses 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 developed to encourage decreased utilization 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 concrete counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference 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 transformed. This can be done using an "excimer laser."
The main purpose of this surgery is to produce a threadlike, rounded "flap" in the cornea using a blade known as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, allowing better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people need to know. Most likely, the main factor why this type of eye surgery has actually become well accepted is due to the fact that the majority of its cases had actually succeeded.
Nevertheless, in spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation used to the most sensitive part of the eye

To puts it simply, a basic mistake might almost cause an individual's lifetime blindness. For this reason, it is very important to think about many factors before deciding whether LASIK eye surgery is the right corrective measure one has to go through.
2. It is not a ideal procedure
LASIK eye surgery might remedy your vision site but it does not necessarily imply that it can provide you a twenty-twenty. Even if statistical reports show this link that 70% of the patients may have 20/20 vision, this does not necessarily suggest they have ideal vision as well.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the perfect eye surgery the method most individuals view it
On the other hand, the assessment of the structural part of the eye may be made in numerous methods. It should be well remembered that a patient with an eye issue might have other issues. Frequently other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can signal the doctor and the patient to problems in some disruptions of other parts of the body even before other symptoms provide themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another form of vision correction.
