The eye can be analyzed with relative ease regarding both its function and its structure. A practical evaluation includes the capability to move in the orbit and the response of the student to light and accommodation.
The function of the eye may be tested in numerous ways. The patient might be asked to recognize illuminated letter or items of differing sizes on what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in several ways. Tension within the eyeball is determined by a "tonometer." In particular illness, particularly in glaucoma, the stress in the eyeball is increased noticeably.
It must be well remembered that a patient with an eye problem might have other problems. Often other physical conditions are primary and impact the eye as a repercussion. The look of the eye can signal the client and the doctor to difficulties in some disturbances of other parts of the body even before other signs provide themselves.
One's dependence on sight is emphasized when one faces a possible or short-lived permanent loss of this essential sense. When restorative steps are sought, certain forms of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are troubled with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to encourage decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction. The only distinction is that with this type of surgical treatment, one's vision is corrected completely.
With LASIK eye surgery, the refractive mistakes in the cornea visit the site are permanently changed. This can be done using an "excimer laser."
The primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, enabling better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that individuals must understand. Most likely, the primary reason this type of eye surgery has ended up being well accepted is due to the fact that the majority of its cases had actually achieved success.
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 involves the operation of the retina, which is among the most sensitive portions of the eye, many people state that the operation can be very dangerous.
To puts it simply, a basic error could nearly trigger an person's life time blindness. Thus, it is very important to think about many elements prior to choosing whether LASIK eye surgical treatment is the right corrective step one needs to go through.
2. It is not a perfect treatment
LASIK eye surgery might remedy your vision but it does not necessarily imply that it can give you a twenty-twenty. Even if analytical reports reveal that 70% of the patients may have 20/20 vision, this does not necessarily mean they have perfect vision too.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not constantly be the ideal eye surgical treatment the way the majority of people see it
On the other hand, the examination of the structural part of the eye may be made in a number of methods. It must be well remembered that a patient with an eye problem may have other issues. Often other physical conditions are primary and impact the eye as a repercussion. The look of the eye can notify the patient and the physician to difficulties in some disruptions of other parts of the body even prior to other symptoms present themselves.
Like its tangible counterpart, LASIK eye surgical treatment is another form of vision correction.
