The eye can be analyzed with relative ease regarding both its function and its structure. A functional examination includes the capability to move in the orbit and the response of the student to light and accommodation.
The function of the eye might be evaluated in numerous ways. The client might be asked to determine illuminated letter or things of differing sizes on exactly what is called the Snellen chart.
Alternatively, the examination of the structural part of the eye might be made in several ways. Tension within the eyeball is determined by a "tonometer." In particular illness, particularly in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it should be well kept in mind that a patient with an eye problem may have other issues as well. Frequently other physical conditions are main and affect the eye as a repercussion. The look of the eye can signal the patient and the physician to problems in some disruptions of other parts of the body even before other symptoms present themselves.
Subsequently, one's reliance on sight is emphasized when one faces a possible or short-term irreversible loss of this crucial sense. For this reason, when restorative measures are sought, certain forms 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 factor, advanced surgeries were established to motivate decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the brief 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 type of surgical treatment, one's vision is remedied completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The primary function of this surgical treatment is to produce 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
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that individuals should know. Most likely, the primary reason why news this type of eye surgery has become well accepted is because the majority of its cases had achieved success.
In spite of its success, there are still some drawbacks. 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 among the most sensitive portions of the eye, the majority of people state that the operation can be very dangerous.
To puts it simply, a easy mistake could nearly cause an individual's life time loss of sight. For this reason, it is very important to think about many elements before choosing whether LASIK eye surgical treatment is the ideal corrective measure one has to undergo.
2. It is not a perfect treatment
LASIK eye surgery may fix your vision but it does not always suggest that it can give you a twenty-twenty. Even if analytical reports reveal that 70% of the patients might have 20/20 vision, this does not necessarily suggest they have ideal vision too.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not constantly be the perfect eye surgical treatment the method the majority of people view it
Alternatively, the evaluation of the structural webpage part of the eye might be made in numerous ways. It must be well remembered that a patient with an eye problem might have other problems. Often other physical conditions are primary and affect the eye as a effect. The look of the eye can alert the patient and the doctor to troubles in some disturbances of other parts of the body even before other symptoms provide themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction.
