The eye can be analyzed with relative ease as to both its function and its structure. A practical assessment consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be tested in numerous ways. The patient may be asked to determine illuminated letter or things of varying sizes on exactly what is called the Snellen chart.
On the other hand, the assessment of the structural part of the eye may be made in several ways. Tension within the eyeball is measured by a "tonometer." In specific diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
It must be well remembered that a client with an eye issue may have other issues. Typically other physical conditions are main and affect the eye as a consequence. The look of the eye can alert the client and the physician to problems in some disruptions of other parts of the body even before other signs present themselves.
One's dependence on sight is highlighted when one deals with a possible or short-lived permanent loss of this important sense. When restorative measures are looked for, specific types of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Basically, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another form of vision correction. The only distinction is that with this type of surgery, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the cornea are permanently changed. This can be done utilizing an "excimer laser."
The main purpose of this surgery is to produce a threadlike, rounded "flap" in the cornea utilizing a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people must understand. Most likely, the primary reason this kind of eye surgical treatment has ended up being well accepted is because the majority of its cases had actually been effective.
In spite of its success, there review are still some downsides. 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 one of the most delicate parts of the eye, many people say that the operation can be very risky.
In other words, a basic error might nearly cause an person's lifetime blindness. It is crucial to consider many aspects prior to choosing whether LASIK eye surgery is the best restorative measure one has to go through.
2. It is not a perfect treatment
LASIK eye surgical treatment may correct your vision but it does not always mean that it can give you a twenty-twenty. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not necessarily imply they have ideal vision.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the perfect eye surgery the way the majority of people see it
On the other hand, the evaluation of the structural part of the eye may be made in numerous ways. It should be well kept in mind that a client with an eye issue might have other problems. Typically other physical conditions are primary and impact the eye as a effect. The look of the eye can inform the doctor and the patient to troubles in some disruptions of other parts of the body even before other symptoms provide themselves.
Like its concrete counterpart, LASIK eye surgery is another kind of vision correction.
