The eye can be examined with relative ease as to both its function and its structure. A functional examination includes the capability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye might be tested in numerous ways. The client may be asked to determine illuminated letter or objects of differing sizes on what is understood as the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In certain diseases, specifically in glaucoma, the stress in the eyeball is increased significantly.
It must be well remembered that a patient with an eye issue might have other problems. Typically other physical conditions are primary and impact the eye as a repercussion. The look of the eye can notify the physician and the client to difficulties in some disturbances of other parts of the body even prior to other symptoms provide themselves.
As a result, one's dependence on sight is emphasized when one deals with a momentary or possible irreversible loss of this essential sense. Thus, when corrective measures are looked for, certain types of vision correction such as contact lenses or glasses are recommended.
On the other hand, some individuals are troubled with the fact that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to motivate decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another kind of vision correction. The only distinction is that with this kind of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgical treatment, 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 known 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.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people must know. Most likely, the main reason that this type of eye surgical treatment has actually ended up being well accepted is because the majority of its cases had achieved success.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation used to the most sensitive part of the eye
Since LASIK eye surgery involves the operation of the retina, which is one of the most delicate parts of the eye, most people say that the operation can be very dangerous.
In other words, a simple error might nearly cause an person's life time loss of sight. Thus, it is necessary to consider numerous factors before choosing whether LASIK eye surgical treatment check is the ideal restorative procedure one has to go through.
2. It is not a ideal treatment
LASIK eye surgery might fix your vision however it does not always suggest that it can give you a best vision. Even if analytical reports show that 70% of the patients may have 20/20 vision, this does not necessarily 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 may not always be the ideal eye surgery the way the majority of people see it
Alternatively, the examination of the structural part of the eye might be made in a number of ways. It should be well kept in mind that a client with an eye problem might have other issues. Typically other physical conditions are primary and affect the eye as a effect. The look of the eye can inform the patient and the physician to troubles in some disruptions of other parts of the body even before other signs provide themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another kind of vision correction.
