The eye can be examined with relative ease as to both its function and its structure. A functional evaluation consists of the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye may be tested in a number of ways. The patient might be asked to identify illuminated letter or things of differing sizes on what is called the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in a number of ways. Tension within the eyeball is measured by a "tonometer." In particular illness, particularly in glaucoma, the tension in the eyeball is increased considerably.
However, it needs to be well kept in mind that a patient with an eye problem might have other issues too. Often other physical conditions are main and impact the eye as a repercussion. The look of the eye can inform the physician and the patient to problems in some disruptions of other parts of the body even before other signs provide themselves.
As a result, one's dependence on sight is emphasized when one deals with a short-term or possible permanent loss of this vital sense. For this reason, when restorative procedures are looked for, particular kinds of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the short-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 fixed completely.
With LASIK eye surgery, the refractive mistakes in the cornea are completely transformed. This can be done using an "excimer laser."
The primary purpose 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 better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people must know. Most likely, the main reason that this type of eye surgery has actually become well accepted is due to the fact that most of its cases had succeeded.
Nevertheless, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation used to the most delicate part of the eye
Because LASIK eye surgical treatment includes 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 dangerous.
Simply puts, a basic mistake could practically trigger an person's life time blindness. Thus, it is essential to consider many factors before deciding whether LASIK eye surgical treatment is the ideal corrective measure one has to undergo.
2. It is not a ideal treatment
LASIK eye surgical treatment may fix your vision however it does not always suggest that it can offer you a twenty-twenty. Even if analytical reports show that 70% of the patients might have 20/20 vision, this does not necessarily mean they have perfect vision.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the perfect eye surgical treatment the way the majority of individuals view it
Conversely, the assessment of the structural part of the eye may be made in a number of methods. It should be well remembered that a client with an eye issue may have other problems. Often other physical conditions are primary and impact the Resources eye as a effect. The look of the eye can notify the client and the doctor to problems in some disruptions of other parts of the body even prior to other signs provide themselves.
Like its tangible counterpart, LASIK eye surgery is another form of vision correction.
