The eye can be examined with relative ease regarding both its function and its structure. A functional examination consists of the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye may be tested in several ways. The patient might be asked to identify illuminated letter or items of differing sizes on what is called the Snellen chart.
Alternatively, the examination of the structural part of the eye might be made in several methods. Tension within the eyeball is determined by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
It must be well kept in mind that a patient with an eye problem might have other issues. Typically other physical conditions are primary and affect the eye as a effect. The appearance of the eye can inform the physician and the client to troubles in some disruptions of other parts of the body even before other symptoms present themselves.
Subsequently, one's dependence on sight is emphasized when one faces a short-lived or possible long-term loss of this crucial sense. For this reason, when restorative procedures are looked for, specific types of vision correction such as contact lenses or spectacles are recommended.
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 reason, advanced surgeries were established to encourage decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction. The only distinction is that with this type of surgery, one's vision is remedied permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently changed. This can be done using an "excimer laser."
The primary purpose of this surgical treatment 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, permitting much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of helpful resources the growing popularity of LASIK eye surgical treatment, there are still disadvantages that individuals must know. Most likely, the primary reason that this type of eye surgical treatment has become well accepted is due to the fact that the majority of its cases had actually succeeded.
In spite of its success, there are still some downsides. 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 includes the operation of the retina, which is among the most sensitive parts of the eye, the majority of people state that the operation can be very dangerous.
In other words, a easy mistake might almost trigger an person's life time blindness. For this reason, it is important to think about lots of factors before choosing whether LASIK eye surgical treatment is the ideal corrective step one needs to go through.
2. It is not a best procedure
LASIK eye surgery might correct your vision but it does not necessarily imply that it can provide you a twenty-twenty. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not always suggest they have perfect vision.
Provided 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 examination of the structural part of the eye may be made in numerous methods. It needs to be well kept in mind that a patient with an eye issue may have other problems. Often other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can alert the physician and the client to problems in some disturbances of other parts of the body even prior to other signs present themselves.
Like its concrete equivalent, LASIK eye surgery is another kind of vision correction.
