The eye can be analyzed with relative ease as to both its function and its structure. A practical examination includes 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 client might be asked to determine illuminated letter or things of varying 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 methods. Tension within the eyeball is determined by a "tonometer." In certain diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it needs to be well kept in mind that a client with an eye problem might have other issues too. Typically other physical conditions are primary and affect the eye as a effect. The appearance of the eye can inform the client and the physician to troubles in some disruptions of other parts of the body even before other signs provide themselves.
Consequently, one's dependence on sight is highlighted when one deals with a temporary or possible irreversible loss of this vital sense. Thus, when corrective procedures are looked for, certain forms of vision correction such as contact lenses or glasses are recommended.
On the other hand, some individuals are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery 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 type of surgery, one's vision is corrected completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely changed. This can be done using an "excimer laser."
The main purpose of this surgery is to create a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing much 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 individuals must understand. Probably, the primary reason that this type of eye surgical treatment has ended up being well accepted is since the majority of its my explanation cases had achieved success.
Nevertheless, 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 includes the operation of the retina, which is one of the most sensitive parts of the eye, many people say that the operation can be really risky.
In other words, a easy mistake could practically trigger an individual's life time blindness. For this reason, it is necessary to think about many aspects before deciding whether LASIK eye surgical treatment is the ideal corrective step one needs to go through.
2. It is not a ideal treatment
LASIK eye surgical treatment might correct your vision but it does not necessarily imply that it can offer you a twenty-twenty. Even if analytical reports reveal that 70% of the patients may have 20/20 vision, this does not necessarily imply they have ideal vision.
Offered all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the ideal eye surgery the way the majority of people see it
Conversely, the examination of the structural part of the eye may be made in numerous methods. It needs to be well kept in mind that a client with an eye problem might have other issues. Typically other physical conditions are main and affect the eye as a repercussion. The appearance of the eye can alert the doctor and the patient to problems in some disturbances of other parts of the body even prior to other signs present themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction.
