The eye can be analyzed with relative ease as to both its function and its structure. A functional examination consists of the capability to relocate the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be evaluated in several methods. The patient might be asked to determine illuminated letter or objects of varying sizes on exactly what is known as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in numerous methods. Stress within the eyeball is determined by a "tonometer." In certain illness, particularly in glaucoma, the stress in the eyeball is increased noticeably.
It should be well kept in mind that a client with an eye problem might have other issues. Often other physical conditions are main and affect the eye as a consequence. The appearance of the eye can signal the physician and the client to troubles in some disturbances of other parts of the body even prior to other symptoms present themselves.
One's reliance on sight is highlighted when one faces a short-lived or possible irreversible loss of this important sense. When restorative procedures are sought, certain forms of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are bothered with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Essentially, 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 surgery, one's vision is corrected completely.
With LASIK eye surgery, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The main function of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade known as "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 popularity of LASIK eye surgery, there are still disadvantages that people need to understand. Probably, the main reason this kind of eye surgical treatment has become well accepted is because the majority of its cases had actually been effective.
However, in spite of its success, there are still some downsides. Here is the list:
1. It is an index operation used to the most sensitive part of the eye
Since LASIK eye surgery involves the operation of the retina, which is among the most sensitive parts of the eye, the majority of people say that the operation can be extremely dangerous.
In other words, a simple mistake might practically trigger an individual's lifetime loss of sight. It is essential to consider many factors before deciding whether LASIK eye surgery is the best corrective measure one has to go through.
2. It is not a perfect procedure
LASIK eye surgery may correct your vision but it does not necessarily suggest that it can give you a twenty-twenty. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not always indicate they have ideal vision.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not always be the perfect eye surgical treatment the way the majority of people see it
Alternatively, the assessment 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 problem may have other issues. Frequently other physical conditions are primary and impact the eye as a consequence. The look of the eye can signal the client and the physician to troubles in some disruptions of other parts of the body even prior to other symptoms present themselves.
Like its tangible counterpart, LASIK eye surgery is another form of vision correction.
