The eye can be examined with relative ease as to both its function and its structure. A practical assessment consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be evaluated in numerous methods. The client may be asked to determine illuminated letter or things of differing sizes on exactly what is referred to as the Snellen chart.
Conversely, the assessment of the structural part of the eye might be made in numerous methods. Stress within the eyeball is determined by a "tonometer." In specific diseases, particularly in glaucoma, the tension in the eyeball is increased noticeably.
It should be well kept in mind that a client with an eye issue might have other problems. Often other physical conditions are main and affect the eye as a effect. The appearance of the eye can notify the doctor and the patient to troubles in some disruptions of other parts of the body even prior to other signs present themselves.
One's reliance on sight is stressed when one deals with a short-lived or possible permanent loss of this crucial sense. When corrective measures are sought, particular forms of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some individuals are troubled with the fact 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 distinction is that with this kind of surgical treatment, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The main purpose 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, allowing 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 understand. Most likely, the main reason this type of eye surgery has ended up being well accepted is since most 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 applied to the most sensitive part of the eye
Because LASIK eye surgery includes the operation of the retina, which is among the most sensitive portions of the eye, many people say that the operation can be really dangerous.
Simply puts, a basic error could practically trigger an person's life time blindness. It is crucial to consider many elements prior to deciding whether LASIK eye surgical treatment is the ideal corrective step one has to go through.
2. It is not a best procedure
LASIK eye surgery might remedy anchor your vision but it does not always imply that it can provide you a twenty-twenty. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not always suggest they have ideal vision.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the perfect eye surgery the way many people see it
On the other hand, the evaluation of the structural part of the eye may be made in a number of ways. It must be well kept in mind that a patient with an eye problem might have other issues. Frequently other physical conditions are main and affect the eye as a repercussion. The appearance of the eye can notify the doctor and the client to problems in some disturbances of other parts of the body even before other symptoms provide themselves.
Like its concrete equivalent, LASIK eye surgery is another form of vision correction.
