The eye can be analyzed with relative ease regarding both its function and its structure. A practical examination includes the ability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be checked in numerous ways. The client may be asked to determine illuminated letter or items of differing sizes on what is understood as the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In particular illness, particularly in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it must be well remembered that a client with an eye issue might have other problems as well. Often other physical conditions are primary and affect the eye as a effect. The appearance of the eye can notify the patient and the physician to problems in some disturbances of other parts of the body even before other signs provide themselves.
One's dependence on sight is stressed when one deals with a possible or short-lived permanent loss of this essential sense. When restorative procedures are looked for, specific forms of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some individuals are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were developed to motivate reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgical treatment 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 surgical treatment, one's vision is fixed completely.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently changed. 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 referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling much 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 individuals should know. Probably, the primary factor why this kind of eye surgery has ended up being well accepted is due to the fact that most of its cases had been effective.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation used to the most delicate 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 sensitive portions of the eye, a lot of people say that the operation can be extremely risky.
Simply puts, a easy error could almost trigger an individual's lifetime blindness. Hence, check that it is very important to think about many aspects before choosing whether LASIK eye surgery is the right restorative procedure one needs to go through.
2. It is not a best treatment
LASIK eye surgery might fix your vision but it does not necessarily imply that it can offer you a twenty-twenty. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily mean they have ideal vision too.
Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the ideal eye surgery the way a lot of individuals see it
On the other hand, the examination of the structural part of the eye might be made in numerous ways. It must be well kept in mind that a client with an eye issue may have other problems. Often other physical conditions are primary and impact the eye as a effect. The look of the eye can alert the patient and the physician to difficulties in some disturbances of other parts of the body even prior to other symptoms provide themselves.
Like its concrete equivalent, LASIK eye surgery is another kind of vision correction.
