The eye can be examined with relative ease regarding both its function and its structure. A functional assessment includes the capability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye might be evaluated in several methods. The client may be asked to recognize illuminated letter or items of differing sizes on what is understood as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In particular diseases, particularly in glaucoma, the tension in the eyeball is increased significantly.
However, it needs to be well kept in mind that a patient with an eye problem may have other problems too. Often other physical conditions are main and impact the eye as a effect. The look of the eye can alert the doctor and the patient to problems in some disruptions of other parts of the body even before other symptoms provide themselves.
As a result, one's reliance on sight is stressed when one deals with a short-lived or possible long-term loss of this essential sense. Hence, when restorative measures are sought, certain types of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals are bothered 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 reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgery is another type of vision correction. The only difference is that with this kind of surgical treatment, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently changed. This can be done using an "excimer laser."
The main purpose of this surgery is to create 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, enabling better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgery, there are still disadvantages that people need to understand. Most likely, the primary factor why this kind of eye surgery has become well accepted is since most of its cases had actually succeeded.
However, in spite of its success, there are still see post some drawbacks. Here is the list:
1. It is an operation used to the most delicate part of the eye
Because LASIK eye surgical treatment involves the operation of the retina, which is one of the most sensitive parts of the eye, a lot of people state that the operation can be extremely risky.
In other words, a basic error might almost trigger an person's lifetime loss of sight. It is important to think about many elements prior to choosing whether LASIK eye surgery is the right corrective step one has to go through.
2. It is not a perfect treatment
LASIK eye surgery may fix your vision however it does not always imply that it can provide you a twenty-twenty. Even if statistical reports show that 70% of the patients might have 20/20 vision, this does not necessarily imply they have perfect vision also.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the ideal eye surgery the method the majority of people see it
Alternatively, the assessment of the structural part of the eye might be made in a number of methods. It must be well kept in mind that a client with an eye problem may have other issues. Frequently other physical conditions are primary and affect the eye as a consequence. The look of the eye can notify the doctor and the client to problems in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Like its concrete equivalent, LASIK eye surgery is another form of vision correction.
