The eye can be taken a look at with relative ease as to both its function and its structure. A functional assessment includes the ability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be checked in numerous methods. The client might be asked to identify illuminated letter or things of differing sizes on exactly what is referred to as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye may be made in several ways. Tension within the eyeball is measured by a "tonometer." In specific illness, particularly in glaucoma, the stress in the eyeball is increased markedly.
However, it ought to be well kept in mind that a client with an eye issue might have other issues too. Frequently other physical conditions are primary and affect the eye as a effect. The look of the eye can inform the doctor and the patient to problems in some disturbances of other parts of the body even before other signs present themselves.
One's dependence on sight is stressed when one faces a momentary or possible irreversible loss of this crucial sense. Thus, when restorative steps are looked for, certain kinds of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are troubled with 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 usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another form of vision correction. The only distinction is that with this kind of surgical treatment, one's vision is remedied permanently.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently transformed. This can be done using an "excimer laser."
The primary purpose 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 lastly 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 surgical treatment, there are still disadvantages that people need to understand. Most likely, the main reason why this type of eye surgical treatment has become well accepted is due to the fact that many of its cases had achieved success.
However, 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
Because LASIK eye surgery includes the operation of the retina, which is among the most delicate portions of the eye, the majority of people state that the operation can be really risky.
In other words, a basic mistake might nearly cause an individual's life time blindness. It is click essential to think about numerous factors prior to deciding whether LASIK eye surgical treatment is the right restorative step one has to go through.
2. It is not a perfect treatment
LASIK eye surgical treatment might correct your vision but it does not necessarily suggest that it can offer you a ideal vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily imply they have ideal vision.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgery the method many individuals see it
On the other hand, the assessment of the structural part of the eye might be made in several methods. It should be well kept in mind that a client with an eye problem may have other problems. Often 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 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.
