The eye can be analyzed with relative ease as to both its function and its structure. A functional examination consists of the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye might be checked in numerous ways. The client may be asked to recognize illuminated letter or items of differing sizes on what is understood as the Snellen chart.
Alternatively, the examination of the structural part of the eye might be made in several ways. Tension within the eyeball is measured by a "tonometer." In certain diseases, particularly in glaucoma, the tension in the eyeball is increased noticeably.
Nevertheless, it should be well kept in mind that a patient with an eye problem may have other issues also. Often other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can signal the physician and the client to difficulties in some disturbances of other parts of the body even before other signs provide themselves.
Subsequently, one's dependence on sight is emphasized when one faces a short-lived 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 bothered with the fact that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were established to encourage reduced usage of contact lenses or glasses. Among 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 counterpart, LASIK eye surgery is another kind of vision correction. The only distinction is that with this type of surgery, one's vision is remedied permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently transformed. This can be done using an "excimer laser."
The main click for more purpose of this surgical treatment is to produce 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, enabling much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people must understand. Probably, the primary factor why this kind of eye surgery has become well accepted is since 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 applied to the most sensitive part of the eye
Since LASIK eye surgery involves 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.
To puts it simply, a simple error might almost cause an individual's life time loss of sight. Hence, it is necessary to think about lots of factors before deciding whether LASIK eye surgical treatment is the ideal corrective measure one needs to go through.
2. It is not a perfect procedure
LASIK eye surgery may fix your vision but it does not necessarily indicate that it can offer you a perfect vision. Even if statistical reports show that 70% of the clients might have 20/20 vision, this does not always 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 always be the ideal eye surgical treatment the method many people view it
Alternatively, the examination of the structural part of the eye may be made in several methods. It needs to be well kept in mind that a client with an eye problem might have other problems. Often other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can notify the client and the physician to difficulties in some disturbances of other parts of the body even before other symptoms present themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another form of vision correction.
