The eye can be taken a look at with relative ease regarding both its function and its structure. A functional examination includes the capability to relocate the orbit and the reaction of the student to light and lodging.
The function of the eye might be checked in several ways. The patient might be asked to recognize illuminated letter or things of varying sizes on exactly what is understood as the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in numerous ways. Tension within the eyeball is determined by a "tonometer." In specific illness, particularly in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it ought to be well kept in mind that a patient with an eye problem may have other problems also. Typically other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can alert the doctor and the patient to troubles in some disruptions of other parts of the body even before other symptoms provide themselves.
One's reliance on sight is emphasized when one faces a short-term or possible long-term loss of this essential sense. When corrective measures are sought, specific forms of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are bothered with the fact that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were established to encourage reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgery is another form of vision correction. The only distinction is that with this type of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The main function of this surgery is to develop 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, allowing much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgery, there are still disadvantages that individuals must understand. Probably, the main reason that this kind of eye surgery has actually become well accepted is because the majority of its cases had achieved success.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Because LASIK eye surgical treatment includes the operation of the retina, which is among the most sensitive portions of the eye, many people say that the operation can be extremely risky.
To puts it simply, a simple error might nearly trigger an individual's life time loss of sight. It is important to think about lots of aspects prior to deciding whether LASIK eye surgical treatment is the best corrective step one has to undergo.
2. It is not a ideal treatment
LASIK eye surgical treatment may correct your vision however it does not always indicate that it can give you a twenty-twenty. Even if statistical reports reveal that 70% of the patients might have 20/20 vision, this does not always suggest they have perfect vision.
Offered 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 view it
Conversely, the assessment of the structural part of the eye may be made in several methods. It needs to be well remembered that a patient with an eye problem may have other problems. Typically other physical conditions are primary and impact the eye as a effect. The look of the eye can alert the anonymous 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 surgery is another form of vision correction.
