The eye can be examined with relative ease regarding both its function and its structure. A functional examination consists of the capability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in numerous methods. The patient may be asked to recognize illuminated letter or things 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 several ways. Stress within the eyeball is determined by a "tonometer." In specific diseases, specifically in glaucoma, the tension in the eyeball is increased considerably.
However, it should be well kept in mind that a client with an eye problem might have other problems as well. Frequently other physical conditions are main and impact the eye as a effect. The appearance of the eye can notify the client and the physician to difficulties in some disruptions of other parts of the body even before other symptoms provide themselves.
Consequently, one's dependence on sight is emphasized when one deals with a short-lived or possible irreversible loss of this essential sense. When corrective steps are looked for, specific types of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries 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 brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction. The only difference is that with this type of surgical treatment, one's vision is corrected completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently changed. 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 called "microkeratome." In a series of unfolding and laser processing, the cornea is finally 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 surgery, there are still disadvantages that people need to know. Most likely, the main factor why this kind of eye surgery has actually become well accepted is due to the fact that the majority of its cases had actually been successful.
In spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied to the most delicate part of the eye

2. It is not a ideal treatment
LASIK eye surgical treatment might correct your vision but it does not necessarily indicate that it can offer you a twenty-twenty. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily mean they have ideal vision.
Given all these wikipedia reference things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the perfect eye surgical treatment the method many people see it
Alternatively, the assessment of the structural part of the eye might be made in several methods. It must 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 look of the eye can inform the physician and the client to problems in some disturbances of other parts of the body even prior to other symptoms provide themselves.
Like its concrete equivalent, LASIK eye surgery is another type of vision correction.
