The eye can be examined with relative ease regarding both its function and its structure. A practical assessment includes the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye may be evaluated in several methods. The patient might be asked to identify illuminated letter or things of varying sizes on what is called the Snellen chart.
On the other hand, the evaluation of the structural part of the eye may be made in several ways. Tension within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased considerably.
Nevertheless, it must be well bore in mind that a patient with an eye issue may have other problems also. Often other physical conditions are main and affect the eye as a consequence. The look of the eye can signal the patient and the physician to troubles in some disturbances of other parts of the body even before other symptoms present themselves.
One's reliance on sight is stressed when one deals with a temporary or possible permanent loss of this important sense. Thus, when corrective steps are sought, certain forms of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to encourage reduced utilization of contact lenses or glasses. Among 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 counterpart, LASIK eye surgical treatment is another kind of vision correction. The only difference is that with this type of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The primary purpose of this surgical treatment is to produce a threadlike, rounded "flap" in the cornea utilizing 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
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people should understand. Most likely, the primary reason that this kind of eye surgical treatment has actually become well accepted is due to the fact that the majority of its cases had actually succeeded.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Because LASIK eye surgery includes the operation of the retina, which is among the most sensitive parts of the eye, many people state that the operation can be extremely dangerous.
To puts it simply, a basic error might almost cause an person's lifetime blindness. For this reason, it is crucial to think about lots of factors before deciding whether LASIK eye surgery is the right corrective measure one has to undergo.
2. It is not a best procedure
LASIK eye surgery might fix your vision but it does not necessarily suggest that it can give you a perfect vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not always imply they have ideal vision.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgery the way the majority of people see it
Alternatively, the evaluation of the structural part of the eye may be made in numerous methods. It needs to be well remembered that a patient with an eye problem may have other issues. Typically other physical conditions are main and impact the eye as a effect. The look of the eye can inform the patient and the doctor to difficulties in some disturbances of other parts of the body even before other symptoms get more provide themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction.
