The eye can be examined with relative ease regarding both its function and its structure. A practical assessment consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be tested in several methods. The client may be asked to identify illuminated letter or objects of varying sizes on exactly what is referred to as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in several methods. Stress within the eyeball is measured by a "tonometer." In certain illness, particularly in glaucoma, the stress in the eyeball is increased markedly.
Nevertheless, it must be well kept in mind that a patient with an eye issue might have other issues also. Typically other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can signal the patient and the physician to problems in some disruptions of other parts of the body even before other signs present themselves.
Subsequently, one's dependence on sight is highlighted when one deals with a possible or short-term irreversible loss of this crucial sense. Thus, when corrective measures are sought, certain kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgery 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 surgical treatment, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently changed. 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 using a blade understood as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgery, there are still disadvantages that individuals must understand. Probably, the main factor why this kind of eye surgery has ended up being well accepted is because most of its cases had achieved success.
However, 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 surgical treatment includes the operation of the retina, which is among the most sensitive portions of the eye, many people say that the operation can be extremely risky.
To puts it simply, a basic mistake might almost cause an person's life time loss of sight. Hence, it is essential to consider many factors before choosing whether LASIK eye surgical treatment is the best corrective measure one needs to go through.
2. It is not a best treatment
LASIK eye surgery might remedy your vision but it does not necessarily indicate that it can give you a twenty-twenty. Even if analytical reports show that 70% of the clients may have 20/20 vision, this does not always imply they have perfect vision as well.
Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not constantly be the ideal eye surgical treatment the way the majority of individuals see it
Alternatively, the examination of the structural part of the eye may be made in a number of ways. It ought to be well remembered that a patient with an eye issue may have other issues. Often other physical conditions are primary and affect the eye as a consequence. The look of the eye can alert the patient and the doctor to troubles in some disruptions of other parts of the body even before other signs provide More about the author themselves.
