The eye can be examined with relative ease regarding both its function and its structure. A practical evaluation 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 checked in a number of methods. The patient might be asked to determine illuminated letter or objects of differing sizes on what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in several ways. Stress within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the stress in the eyeball is increased considerably.
Nevertheless, it must be well kept in mind that a patient with an eye issue might have other issues too. Frequently other physical conditions are main and impact the eye as a consequence. The look of the eye can alert the patient and the doctor to problems in some disruptions of other parts of the body even prior to other symptoms present themselves.
One's dependence on sight is emphasized when one faces a momentary or possible irreversible loss of this vital sense. Thus, when corrective procedures are sought, particular kinds of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are bothered with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate 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 type of vision correction. The only difference 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 primary function of this surgery is to develop 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 lastly reformed, allowing much better the eye to direct more light into the retina.
Appeal vs. Disadvantages

Nevertheless, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Because LASIK eye surgical treatment go now includes the operation of the retina, which is among the most delicate portions of the eye, many people state that the operation can be extremely dangerous.
In other words, a simple error might almost trigger an individual's lifetime blindness. It is crucial to think about numerous aspects before deciding whether LASIK eye surgery is the right restorative procedure one has to undergo.
2. It is not a best treatment
LASIK eye surgery might fix your vision but it does not necessarily mean that it can offer you a twenty-twenty. Even if statistical reports reveal that 70% of the patients may have 20/20 vision, this does not necessarily suggest they have perfect vision also.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the ideal eye surgical treatment the way the majority of people view it
Conversely, the evaluation of the structural part of the eye might be made in a number of methods. It needs to be well remembered that a patient with an eye issue might have other problems. Typically other physical conditions are primary and affect the eye as a consequence. The look of the eye can notify the doctor and the client to difficulties in some disturbances of other parts of the body even prior to other symptoms provide themselves.
