The eye can be examined 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 pupil to light and accommodation.
The function of the eye might be tested in a number of ways. The patient might be asked to identify illuminated letter or objects of differing sizes on what is referred to as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the stress in the eyeball is increased noticeably.
It needs to be well kept in mind that a patient with an eye issue may have other problems. Frequently other physical conditions are main and affect the eye as a consequence. The look of the eye can inform the doctor and the patient to problems in some disruptions of other parts of the body even before other symptoms present themselves.
As a result, one's reliance on sight is emphasized when one faces a momentary or possible irreversible loss of this vital sense. When restorative procedures are sought, particular kinds of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are troubled with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to encourage decreased 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 concrete equivalent, LASIK eye surgery is another form of vision correction. The only distinction is that with this kind of surgery, one's vision is fixed permanently.
With LASIK eye surgery, the refractive errors in the cornea are permanently transformed. 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 lastly reformed, allowing better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgery, there are still disadvantages that people must know. Probably, the main reason this type of eye surgical treatment has actually ended up being well accepted is due to the fact that 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 involves the operation of the retina, which is one of the most sensitive parts of the eye, most people say that the operation can be very dangerous.
To puts it simply, a simple error could almost cause an individual's lifetime blindness. Thus, it is necessary to think about lots of aspects before choosing whether LASIK eye surgery is the ideal corrective measure one needs to go through.
2. It is not a ideal procedure
LASIK eye surgery may correct your vision but it does not always mean that it can give you a best vision. Even if statistical reports show that 70% of the clients might have 20/20 vision, this does not necessarily mean 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 perfect eye surgical treatment the way many individuals see it
