The eye can be taken a look at with relative ease as to both its function and its structure. A practical assessment consists of the ability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye may be checked in numerous ways. The client might be asked to identify illuminated letter or items of differing sizes on what is referred to as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye might be made in a number of ways. Stress within the eyeball is determined by a "tonometer." In certain illness, especially in glaucoma, the tension in the eyeball is increased noticeably.
However, it needs to be well bore in mind that a patient with an eye problem might have other issues as well. Frequently other physical conditions are primary and affect the eye as a consequence. The look of the eye can signal the patient and the physician to troubles in some disruptions of other parts of the body even prior to other symptoms provide themselves.
One's dependence on sight is highlighted when one faces a short-term or possible permanent loss of this essential sense. Hence, when restorative steps are sought, particular forms 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 actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to encourage reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the brief 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 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 main purpose of this surgery is to create a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people must understand. Most likely, the primary reason that this type of eye surgical treatment has actually become well accepted is because the majority of its cases had actually succeeded.
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 may correct your vision but it does not always mean that it can give you a next page twenty-twenty. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily suggest they have perfect vision too.
Provided 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 way the majority of people view it
Conversely, the examination of the structural part of the eye might be made in numerous methods. It must be well remembered that a patient with an eye problem may have other problems. Frequently other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can alert the doctor and the patient to difficulties in some disturbances of other parts of the body even prior to other symptoms present themselves.
