The eye can be examined with relative ease as to both its function and its structure. A practical evaluation consists of the capability to relocate the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be evaluated in numerous methods. The patient might be asked to recognize illuminated letter or objects of varying sizes on exactly what is understood as the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in a number of methods. Tension within the eyeball is determined by a "tonometer." In specific diseases, particularly in glaucoma, the tension in the eyeball is increased considerably.
It needs to be well remembered that a client with an eye issue may have other problems. Often other physical conditions are main and affect the eye as a repercussion. The look of the eye can alert the physician and the client to difficulties in some disruptions of other parts of the body even before other signs provide themselves.
Subsequently, one's dependence on sight is highlighted when one faces a possible or short-term permanent loss of this crucial sense. When corrective procedures are looked for, particular kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are bothered with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this type of surgery, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely 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 using a blade called "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.
Appeal vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people should know. Probably, the primary reason this kind of eye surgery has actually ended up being well accepted is because the majority of its cases had actually achieved success.
However, 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 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.
To puts it simply, a basic error might nearly cause an person's lifetime blindness. It is important to think about many elements before find more deciding whether LASIK eye surgery is the right restorative measure one has to undergo.
2. It is not a ideal procedure
LASIK eye surgery may remedy your vision but it does not necessarily mean that it can provide you a best vision. Even if analytical reports show that 70% of the patients might have 20/20 vision, this does not always suggest they have perfect vision also.
Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgery the way the majority of people view it
On the other hand, the assessment of the structural part of the eye might be made in several methods. It should be well remembered that a patient with an eye issue may have other problems. Often other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can signal the client and the physician to troubles in some disturbances of other parts of the body even before other signs provide themselves.
Like its tangible equivalent, LASIK eye surgery is another form of vision correction.
