The eye can be examined with relative ease regarding both its function and its structure. A functional assessment includes the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye might be checked in numerous ways. The patient may be asked to recognize illuminated letter or objects of differing sizes on what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye might be made in several ways. Tension within the eyeball is measured by a "tonometer." In particular illness, especially in glaucoma, the tension in the eyeball is increased noticeably.
It must be well kept in mind that a client with an eye problem might have other problems. Typically other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can signal the patient and the physician to troubles in some disruptions of other parts of the body even prior to other signs present themselves.
Consequently, one's reliance on sight is stressed when one faces a short-term or possible long-term loss of this crucial sense. When corrective measures are looked for, specific types of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another kind of vision correction. The only difference 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 surgery is to develop a threadlike, rounded "flap" in the cornea using a blade referred to 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 appeal of LASIK eye surgery, there are still disadvantages that individuals should understand. Probably, the main reason this type of eye surgery has ended up being well accepted is due to the fact that most of its cases had succeeded.
However, in spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Due to the fact that LASIK eye surgery involves the operation of the retina, which is one of the most delicate parts of the eye, the majority of people state that the operation can be really risky.
In other words, a basic error right here could nearly cause an individual's life time loss of sight. It is crucial to think about numerous factors prior to deciding whether LASIK eye surgery is the ideal restorative measure one has to go through.
2. It is not a ideal procedure
LASIK eye surgical treatment may remedy your vision but it does not necessarily mean that it can provide you a perfect vision. Even if analytical reports reveal that 70% of the clients may have 20/20 vision, this does not always indicate they have perfect vision also.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the ideal eye surgical treatment the way the majority of people see it
On the other hand, the assessment of the structural part of the eye may be made in a number of methods. It needs to be well remembered that a patient with an eye problem might have other issues. Typically other physical conditions are main and impact the eye as a effect. The look of the eye can alert the patient and the physician to difficulties in some disturbances of other parts of the body even before other symptoms present themselves.
Like its tangible counterpart, LASIK eye surgery is another type of vision correction.
