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 pupil to light and lodging.
The function of the eye may be evaluated in a number of ways. The client may be asked to determine 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 numerous ways. Stress within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the stress in the eyeball is increased markedly.
It must be well kept in mind that a client 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 doctor and the patient to problems in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Consequently, one's dependence on sight is highlighted when one faces a temporary or possible long-term loss of this vital sense. For this reason, when corrective procedures are looked for, certain kinds of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals 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 reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Generally, LASIK eye surgical treatment 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 corrected permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done utilizing an "excimer laser."
The main function of this surgical treatment is to create a threadlike, rounded "flap" in the cornea using a blade referred to his explanation 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
Amidst the growing popularity of LASIK eye surgery, there are still disadvantages that individuals must know. Probably, the main reason this type of eye surgical treatment has become well accepted is since the majority of its cases had 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 one of the most sensitive portions of the eye, the majority of people say that the operation can be extremely risky.
To puts it simply, a basic mistake could almost cause an person's life time blindness. Thus, it is essential to think about many elements before choosing whether LASIK eye surgical treatment is the ideal restorative procedure one has to go through.
2. It is not a ideal treatment
LASIK eye surgery may remedy your vision but it does not always imply that it can offer you a twenty-twenty. Even if statistical reports reveal that 70% of the clients may have 20/20 vision, this does not always imply they have perfect vision.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the ideal eye surgery the method a lot of individuals see it
On the other hand, the examination of the structural part of the eye may be made in a number of methods. It should be well kept in mind that a patient with an eye problem might have other issues. Typically other physical conditions are primary and impact the eye as a repercussion. The look of the eye can signal the patient and the physician to difficulties in some disturbances of other parts of the body even prior to other symptoms present themselves.
Like its tangible counterpart, LASIK eye surgery is another form of vision correction.
