The eye can be examined with relative ease regarding both its function and its structure. A practical assessment consists of the capability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye might be checked in several methods. The client may be asked to determine illuminated letter or objects of differing sizes on what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in a number of ways. Tension within the eyeball is determined by a "tonometer." In particular illness, specifically in glaucoma, the stress in the eyeball is increased noticeably.
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 effect. The appearance of the eye can notify the client and the doctor to problems in some disturbances of other parts of the body even before other symptoms provide themselves.
Subsequently, one's reliance on sight is emphasized when one deals with a possible or temporary permanent loss of this important sense. Hence, when corrective steps are sought, certain forms of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are bothered with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to motivate decreased usage of contact lenses or glasses. One of 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 counterpart, LASIK eye surgery is another form of vision correction. The only difference is that with this kind of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely changed. This can be done using an "excimer laser."
The main purpose of this surgery is to produce 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
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that individuals should understand. Most likely, the main reason this kind of eye surgical treatment has become well accepted is due to the fact that the majority of its cases had succeeded.
In spite of its success, there are still some disadvantages. 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 includes the operation of the retina, which is one of the most delicate parts of the eye, the majority of people say that the operation can be really risky.
In other words, a basic mistake could nearly cause an individual's life time loss of sight. It is important to consider numerous aspects prior to choosing whether LASIK eye surgery is the best restorative procedure one has to go through.
2. It is not a ideal treatment
LASIK eye surgical treatment might fix your vision but it does not always mean that it can offer you a ideal vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not always suggest they have perfect vision also.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not constantly be the perfect eye surgery the way the majority of people view it
Conversely, the examination of the structural part of the eye may be made in numerous methods. It must be well kept in mind that a patient with an eye problem may have other issues. Frequently other physical conditions are main and webpage impact the eye as a repercussion. The appearance of the eye can inform the patient and the doctor to difficulties in some disruptions of other parts of the body even prior to other signs present themselves.
Like its concrete equivalent, LASIK eye surgery is another type of vision correction.
