The eye can be analyzed with relative ease as to both its function and its structure. A practical evaluation consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be evaluated in a number of ways. The patient may be asked to recognize illuminated letter or things of differing sizes on what is understood as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye might be made in several ways. Tension within the eyeball is determined by a "tonometer." In certain diseases, particularly in glaucoma, the stress in the eyeball is increased considerably.
Nevertheless, it should be well remembered that a patient with an eye issue may have other issues too. Frequently other physical conditions are primary and affect the eye as a repercussion. The look of the eye can alert the patient and the physician to problems in some disruptions of other parts of the body even prior to other signs provide themselves.
One's reliance on sight is stressed when one faces a possible or momentary irreversible loss of this essential sense. When corrective measures are sought, certain kinds of vision correction such as contact lenses or glasses 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 factor, advanced surgical operations were developed to motivate decreased usage 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 type of vision correction. The only distinction is that with this type of surgical treatment, one's vision is corrected permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The primary function of this surgical treatment is to develop 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.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that individuals must know. Probably, the main reason that this type of eye surgical treatment has become well accepted is due to the fact that most of its cases had actually been successful.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most delicate part of the eye

2. It is not a ideal procedure
LASIK eye surgery might correct your vision however it does not always indicate that it can give you a ideal vision. Even if statistical reports reveal that 70% of the patients may have 20/20 vision, this does not always imply they have ideal vision.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the ideal eye surgical treatment the way the majority of people see it
Conversely, the assessment of the structural part of the eye may be made in a number of ways. It should be well remembered that a patient with an eye problem might have other issues. Frequently other physical conditions are main and affect the eye as a repercussion. The look of the eye can inform the client and the doctor to problems in some disturbances of other parts of the body even before other signs present themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another kind of vision correction.
