The eye can be examined with relative ease as to both its function and its structure. A functional examination consists of the ability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in a number of ways. The client might be asked to determine illuminated letter or items of differing sizes on exactly what is understood as the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in a number of ways. Tension within the eyeball is measured by a "tonometer." In particular illness, specifically in glaucoma, the stress in the eyeball is increased markedly.
Nevertheless, it should be well kept in mind that a patient with an eye issue may have other problems as well. Typically other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can inform the client and the doctor to difficulties in some disruptions of other parts of the body even prior to other signs provide themselves.
Consequently, one's dependence on sight is highlighted when one deals with a possible or momentary long-term loss of this crucial sense. When corrective procedures are sought, particular forms of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are bothered with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another kind of vision correction. The only distinction is that with this type of surgery, one's vision is corrected completely.
With LASIK eye surgical treatment, the view it refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The primary purpose of this surgery is to create 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, permitting better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to understand. Probably, the primary reason this kind of eye surgical treatment has ended up being well accepted is since many of its cases had actually succeeded.
Nevertheless, in spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Because LASIK eye surgical treatment involves the operation of the retina, which is one of the most delicate portions of the eye, many people state that the operation can be very dangerous.
Simply puts, a basic error could nearly cause an person's life time blindness. For this reason, it is very important to consider numerous factors before choosing whether LASIK eye surgery is the best restorative measure one needs to go through.
2. It is not a best treatment
LASIK eye surgery may remedy your vision but it does not necessarily imply that it can offer you a best vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily suggest they have perfect vision too.
Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the ideal eye surgery the way many people view it
On the other hand, the evaluation of the structural part of the eye may be made in several ways. It should be well remembered that a patient with an eye issue may have other problems. Frequently other physical conditions are primary and impact the eye as a effect. The look of the eye can inform the patient and the physician to problems in some disturbances of other parts of the body even prior to other signs present themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another kind of vision correction.
