The eye can be analyzed with relative ease regarding both its function and its structure. A functional assessment includes the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be checked in several ways. The client may be asked to determine illuminated letter or items of varying sizes on what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye might be made in a number of methods. Tension within the eyeball is determined by a "tonometer." In particular illness, especially in glaucoma, the stress in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye issue may have other problems also. Frequently other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can inform the patient and the physician to difficulties in some disturbances of other parts of the body even prior to other symptoms present themselves.
Subsequently, one's dependence on sight is emphasized when one deals with a possible or momentary irreversible loss of this important sense. For this reason, when corrective procedures are looked for, particular types of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another type of vision correction. The only difference is that with this type of surgery, one's vision is remedied permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently changed. This can be done using an "excimer laser."
The primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, permitting better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people should understand. Most likely, the primary reason that this kind of eye surgery has actually become well accepted is due to the fact that the majority of its cases had actually been successful.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Because LASIK eye surgical treatment includes the operation of the retina, which is one of the most delicate portions of the eye, many people say that the operation can be very risky.
To puts it simply, a simple mistake could almost cause an individual's life time loss of sight. Thus, it is necessary to think about numerous aspects before choosing whether LASIK eye surgery is the right corrective procedure one needs to go through.
2. It is not a ideal procedure
LASIK eye surgery may fix your vision but it does not necessarily mean that it can offer you a perfect vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily mean they have ideal vision as well.
Offered all these things, it can be deduced that, in explanation spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgical treatment websites the way a lot of people view it
On the other hand, the examination of the structural part of the eye may be made in several ways. It must be well kept in mind that a patient with an eye problem might have other problems. Frequently other physical conditions are main and affect the eye as a effect. The appearance of the eye can notify the physician and the client to problems in some disturbances of other parts of the body even prior to other symptoms present themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction.
