The eye can be examined with relative ease regarding both its function and its structure. A practical evaluation 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 recognize illuminated letter or items of differing sizes on what is known as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye may be made in several methods. Tension within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the stress in the eyeball is increased markedly.
However, it should be well bore in mind that a patient with an eye problem might have other problems also. Frequently other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can signal the doctor and the patient to troubles in some disruptions of other parts of the body even before other signs present themselves.
One's dependence on sight is highlighted when one deals with a possible or short-term long-term loss of this important sense. When corrective steps are looked for, specific kinds of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were developed to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgery is another type of vision correction. The only difference is that with this type of surgery, one's vision is corrected completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently transformed. This can be done using an "excimer laser."
The main function of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea using a blade understood as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, permitting 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 individuals should understand. Probably, the main reason why this kind of eye surgical treatment has actually ended up being well accepted is due to the fact that many of its cases had been successful.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most sensitive part of the eye
Due to the fact that LASIK eye surgical treatment includes the operation of the retina, which is one of the most delicate portions of the eye, many people state that the operation can be very dangerous.
Simply puts, a simple mistake might almost trigger an individual's life time blindness. Hence, it is very important to consider lots of factors prior to deciding whether LASIK eye surgery is the ideal corrective step one needs to go through.
2. It is not a ideal procedure
LASIK eye surgical treatment might correct your vision however it does not necessarily imply that it can provide you a best vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not always indicate they have perfect vision as well.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgical treatment the method many people view it
Conversely, the evaluation of the structural part of the eye may be made in numerous methods. It needs to be well remembered that a patient with an eye issue may have other issues. Often other physical conditions are primary and affect the eye as a repercussion. The appearance i loved this of the eye can notify the patient and the doctor to problems in some disruptions of other parts of the body even before other signs present themselves.
Like its concrete equivalent, LASIK eye surgery is another form of vision correction.
