The eye can be analyzed with relative ease regarding both its function and its structure. A functional assessment consists of the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye might be tested in numerous methods. The patient may be asked to determine illuminated letter or things of differing sizes on what is called the Snellen chart.
On the other hand, the assessment of the structural part of the eye might be made in several ways. Stress within the eyeball is determined by a "tonometer." In certain diseases, particularly in glaucoma, the stress in the eyeball is increased noticeably.
However, it should be well bore in mind that a patient with an eye problem might have other problems also. Frequently other physical conditions are primary and impact the eye as a repercussion. The look of the eye can alert the patient and the physician to difficulties in some disruptions of other parts of the body even prior to other signs provide themselves.
Consequently, one's reliance on sight is stressed when one faces a temporary or possible irreversible loss of this crucial sense. For this reason, when corrective measures are sought, specific types of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some individuals are bothered with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were developed to encourage reduced usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the brief 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 kind of surgery, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The primary function of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade understood as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling better see post the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgery, there are still disadvantages that people must know. Probably, the main reason this type of eye surgery has actually become well accepted is due to the fact that most of its cases had succeeded.
In spite of its success, there are still some downsides. Here is the list:
1. It is an click for more operation used to the most delicate part of the eye
Because LASIK eye surgery includes the operation of the retina, which is one of the most sensitive parts of the eye, the majority of people say that the operation can be very risky.
In other words, a simple mistake could nearly trigger an individual's lifetime loss of sight. Thus, it is essential to think about lots of aspects prior to deciding whether LASIK eye surgical treatment is the right corrective measure one needs to undergo.
2. It is not a ideal procedure
LASIK eye surgical treatment may remedy your vision but it does not always mean that it can provide you a perfect vision. Even if analytical reports show that 70% of the patients may have 20/20 vision, this does not necessarily suggest they have perfect vision.
Offered all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not always be the perfect eye surgical treatment the way many people view it
Conversely, the assessment of the structural part of the eye might be made in a number of methods. It must be well remembered that a client with an eye problem might have other issues. Typically other physical conditions are primary and impact the eye as a consequence. The look of the eye can inform the client and the physician to difficulties in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Like its concrete counterpart, LASIK eye surgery is another kind of vision correction.
