The eye can be examined with relative ease regarding both its function and its structure. A practical assessment includes the ability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be checked in numerous methods. The client may be asked to identify illuminated letter or things of differing sizes on exactly what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In certain illness, specifically in glaucoma, the stress in the eyeball is increased markedly.
It must be well remembered that a client with an eye problem might have other issues. Typically other physical conditions are primary and affect the eye as a consequence. The look of the eye can inform the physician and the patient to problems in some disruptions of other parts of the body even prior to other symptoms present themselves.
One's reliance on sight is emphasized when one deals with a short-term or possible permanent loss of this essential sense. Hence, when corrective procedures are looked for, particular kinds of vision correction such as contact lenses or glasses are recommended.
On the other hand, some individuals are bothered with the fact that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another kind of vision correction. The only difference is that with this kind of surgery, one's vision is remedied permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done utilizing an "excimer laser."
The primary function of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea utilizing a blade understood as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, enabling much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to understand. Most likely, the primary reason why this type of eye surgery has become well accepted is due to the fact that most of sites its cases had actually been successful.
However, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most delicate part of the eye
Since LASIK eye surgery includes the operation of the retina, which is among the most sensitive parts of the eye, many people say that the operation can be very dangerous.
In other words, a basic mistake might almost trigger an individual's lifetime loss of sight. Thus, it is necessary to consider lots of aspects prior to deciding whether LASIK eye surgical treatment is the right restorative procedure one needs to undergo.
2. It is not a perfect procedure
LASIK eye surgery may fix your vision but it does not necessarily indicate that it can provide you a best vision. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not always suggest they have perfect vision also.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the ideal eye surgery the method most people see it
Alternatively, the assessment of the structural part of the eye might be made in a number of ways. It needs to be well kept in mind that a patient with an eye problem might have other issues. Frequently other physical conditions are primary and impact the eye as a effect. The appearance of the eye can alert the physician and the client to troubles in some disturbances of other parts of the body even before other signs present themselves.
Like its concrete counterpart, LASIK eye surgery is another kind of vision correction.
