The eye can be examined with relative ease as to both its function and its structure. A functional assessment consists of the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye may be tested in several methods. The patient may be asked to recognize illuminated letter or items of varying sizes on exactly what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye might be made in a number of 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 problems also. Often other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can notify the patient and the physician to difficulties in some disruptions of other parts of the body even before other symptoms provide themselves.
One's reliance on sight is stressed when one faces a short-lived or possible irreversible loss of this crucial sense. For this reason, when corrective measures are sought, 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 reason, advanced surgeries were developed to encourage decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another type of vision correction. The only distinction is that with this type of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely transformed. This can be done utilizing an "excimer laser."
The primary purpose of this surgery 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, enabling better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgery, there are still disadvantages that people must know. Probably, the original site main reason this kind of eye surgery has become well accepted is because the majority of its cases had achieved success.
However, 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
Due to the fact that LASIK eye surgical treatment includes the operation of the retina, which is one of the most sensitive portions of the eye, the majority of people state that the operation can be extremely risky.
In other words, a simple mistake might almost cause an individual's lifetime blindness. Thus, it is essential to think about many elements prior to deciding whether LASIK eye surgical treatment is the best corrective step one needs to go through.
2. It is not a best treatment
LASIK eye surgical treatment might remedy your vision but it does not necessarily mean that it can give you a twenty-twenty. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily mean they have perfect vision also.
Given 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 method most individuals view it
Alternatively, the evaluation of the structural part of the eye may be made in a number of methods. It ought to be well remembered that a client with an eye issue may have other problems. Frequently other physical conditions are main and affect the eye as a effect. The look of the eye can signal the physician and the patient to difficulties in some disruptions of other parts of the body even before other signs present themselves.
Like its concrete counterpart, LASIK eye surgery is another form of vision correction.
