The eye can be analyzed with relative ease as to both its function and its structure. A practical evaluation consists of the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye might be tested in a number of ways. The client might be asked to identify illuminated letter or objects of differing sizes on what is known as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in a number of methods. Tension within the eyeball is measured by a "tonometer." In specific illness, specifically in glaucoma, the tension in the eyeball is increased markedly.
It needs to be well remembered that a patient with an eye problem may have other issues. Often other physical conditions are primary and impact the eye as a repercussion. The look of the eye can signal the doctor and the client to problems in some disturbances of other parts of the body even before other symptoms provide themselves.
One's reliance on sight is emphasized when one deals with a possible or short-term long-term loss of this important sense. Hence, when restorative procedures are looked for, particular kinds of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another kind of vision correction. The only difference is that with this type of surgery, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the this content cornea are permanently changed. This can be done utilizing an "excimer laser."
The primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a anchor blade known as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, enabling 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 should know. Most likely, the primary reason that this type of eye surgery has ended up being well accepted is because many of its cases had actually succeeded.
In spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Because LASIK eye surgery includes the operation of the retina, which is one of the most delicate parts of the eye, the majority of people state that the operation can be very risky.
In other words, a simple error could almost cause an individual's life time blindness. Thus, it is crucial to think about many factors before choosing whether LASIK eye surgery is the right restorative step one needs to go through.
2. It is not a ideal procedure
LASIK eye surgery might correct your vision but it does not necessarily mean that it can give you a best vision. Even if analytical reports reveal that 70% of the patients may have 20/20 vision, this does not always mean they have ideal vision.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the ideal eye surgery the method the majority of people view it
Alternatively, the evaluation of the structural part of the eye may be made in several ways. It should be well kept in mind that a patient with an eye issue might have other problems. Frequently other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can signal the doctor and the client to problems in some disturbances of other parts of the body even before other signs present themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction.
