The eye can be analyzed with relative ease as to both its function and its structure. A functional assessment includes the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye might be evaluated in numerous methods. The patient may be asked to determine illuminated letter or items of differing sizes on what is called the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in several methods. Tension within the eyeball is measured by a "tonometer." In particular illness, specifically in glaucoma, the stress in the eyeball is increased markedly.
It needs to be well remembered that a patient with an eye issue might have other problems. Often other physical conditions are main and affect the eye as a consequence. The look of the eye can notify the client and the physician to problems in some disruptions of other parts of the body even before other signs present themselves.
Consequently, one's dependence on sight is emphasized when one deals with a temporary or possible permanent loss of this vital sense. For this reason, when corrective steps are looked for, specific types of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to encourage decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another type of vision correction. The only difference is that with this kind of surgical treatment, one's vision is remedied completely.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently transformed. This can be done using an "excimer laser."
The main function of this surgery is to create a threadlike, rounded "flap" in the cornea using 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.
Popularity vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people must understand. Most likely, the primary reason that this type of eye surgical treatment has actually become well accepted is since the majority of its cases had actually achieved success.
However, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most sensitive 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, the majority of people state that the operation can be very risky.
In other words, a simple mistake could nearly cause an person's life time loss of sight. Thus, it is important to think about many elements before choosing whether LASIK eye surgery is the ideal restorative step one needs to undergo.
2. It is not a perfect treatment
LASIK eye surgery might remedy your vision however it does not necessarily indicate that it can offer you a twenty-twenty. Even if analytical reports reveal that 70% of the clients may have 20/20 vision, this does not necessarily mean they have perfect vision as well.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgical i thought about this treatment the way a lot of people see it
Conversely, the evaluation of the structural part of the eye might be made in a number of ways. It must be well remembered that a patient with an eye issue may have other issues. Frequently other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can inform the client and the doctor to difficulties in some disruptions of other parts of the body even before other signs provide themselves.
Like its tangible counterpart, LASIK eye surgery is another type of vision correction.
