The eye can be examined with relative ease as to both its function and its structure. A functional examination includes the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye might be evaluated in several ways. The patient may be asked to determine illuminated letter or things of varying 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 methods. Tension within the eyeball is determined by a "tonometer." In certain diseases, specifically in glaucoma, the stress in the eyeball is increased markedly.
However, it must be well kept in mind that a client with an eye issue may have other issues also. Often other physical conditions are main and impact the eye as a consequence. The appearance of the eye can inform the patient and the physician to problems in some disruptions of other parts of the body even prior to other signs present themselves.
Subsequently, one's reliance on sight is stressed when one deals with a short-term or possible irreversible loss of this essential sense. When corrective procedures are looked for, specific forms of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are troubled with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to motivate reduced utilization of contact lenses or glasses. Among 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 equivalent, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this kind of surgical treatment, one's vision is remedied completely.
With LASIK eye surgery, 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 finally reformed, enabling much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgery, there are still disadvantages that people must know. Most likely, the primary reason that this kind of eye surgery has become well accepted is since the majority of its cases had actually been effective.
In spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Since LASIK eye surgery involves the operation of the retina, which is one of the most sensitive portions of the eye, the majority of people state that the operation can be extremely risky.
Simply puts, a easy error might almost cause an person's life time loss of sight. For this reason, it is essential to consider many factors prior to choosing whether LASIK eye surgery is the right corrective step one has to go through.
2. It is not a ideal treatment
LASIK eye surgical treatment might correct your vision however it does not necessarily indicate that it can offer you a best vision. Even if analytical reports reveal that 70% of the patients might have 20/20 vision, this does not always suggest they have perfect vision too.
Offered 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 method the majority of people view it
Alternatively, the evaluation of the structural part of the eye may be made in several methods. It needs to be well remembered that a client with an eye issue might have other use this link problems. Often other physical conditions are main and affect the eye as a effect. The appearance of the eye can inform the patient and the physician to difficulties in some disruptions of other parts of the body even before other signs present themselves.
Like its concrete equivalent, LASIK eye surgery is another kind of vision correction.
