The eye can be taken a look at with relative ease regarding both its function and its structure. A practical evaluation consists of the capability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye might be evaluated in several methods. The patient may be asked to recognize illuminated letter or items of varying sizes on what is referred to as the Snellen chart.
Conversely, the assessment of the structural part of the eye might be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it should be well kept in mind that a patient with an eye problem might have other issues too. Typically other physical conditions are main and affect the eye as a consequence. The look of the eye can notify the physician and the client to troubles in some disruptions of other parts of the body even before other symptoms provide themselves.
One's dependence on sight is emphasized when one faces a short-term or possible irreversible loss of this crucial sense. For this reason, when restorative steps are sought, specific forms of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate reduced utilization of contact lenses or glasses. One of 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 equivalent, LASIK eye surgery is another type of vision correction. The only distinction is that with this type of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The primary purpose of this surgery is to produce 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 much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people must know. Most likely, the main reason why this kind of eye surgical treatment has become well accepted is because most of its cases had achieved success.
Nevertheless, in spite of its success, there are still some disadvantages. 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 sensitive portions of the eye, many people say that the operation can be very dangerous.
In other words, a simple mistake could almost trigger an individual's lifetime loss of sight. Thus, it is necessary to consider lots of elements prior to deciding whether LASIK eye surgical treatment is the best corrective measure one has to go through.
2. It is not a best procedure
LASIK eye surgery might correct your vision but it does not necessarily indicate that it can offer you a perfect vision. Even if statistical reports reveal that 70% of the clients may have 20/20 vision, this does not necessarily suggest they have perfect vision.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgery the method many people see it
On the other hand, the assessment of the structural part of view the eye might be made in a number of ways. It needs to be well remembered that a patient with an eye issue might have other issues. Frequently other physical conditions are primary and impact the eye as a consequence. The look of the eye can alert the physician and the patient to troubles in some disruptions of other parts of the body even before other symptoms present themselves.
Like its concrete equivalent, LASIK eye surgery is another form of vision correction.
