The eye can be examined with relative ease as to both its function and its structure. A practical evaluation includes the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye might be checked in a number of ways. The patient may be asked to identify illuminated letter or things of differing sizes on exactly what is referred to as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in numerous ways. Stress within the eyeball is determined by a "tonometer." In specific illness, especially in glaucoma, the stress in the eyeball is increased markedly.
Nevertheless, it needs to be well bore in mind that a patient with an eye problem may have other issues too. Typically other physical conditions are main and affect the eye as a repercussion. The look of the eye can signal the doctor and the client to troubles in some disturbances of other parts of the body even prior to other symptoms provide themselves.
One's dependence on sight is stressed when one faces a possible or momentary permanent loss of this essential sense. Thus, when corrective measures are sought, specific kinds of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people 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 utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction. The only difference is that with this type of surgery, one's vision is corrected permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The main function of this surgical treatment 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 better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgery, there are still disadvantages that people should understand. Probably, the main factor why this type of eye surgical treatment has actually become well accepted is since most of its cases had been successful.
However, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most sensitive 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 parts of the eye, the majority of people state that the operation can be really risky.
In other words, a basic error could practically cause an person's lifetime blindness. Thus, it is very important to think about many aspects prior to choosing whether LASIK eye surgical treatment is the best corrective step one needs to undergo.
2. It is not a ideal procedure
LASIK eye surgical treatment might remedy your vision but it does not necessarily mean that it can give you a best vision. Even if analytical reports show that 70% of the patients might have 20/20 vision, this does not always indicate they have perfect vision as well.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not always be the perfect eye surgical treatment the way the majority of people view it
Conversely, the assessment of the structural part of the eye might be made in a number of ways. It ought to be well remembered that a patient with an eye issue might have other problems. Often other physical conditions are main and impact the eye as a effect. The look page of the eye can notify the patient and the doctor to troubles in some disruptions of other parts of the body even before other symptoms provide themselves.
Like pop over here its tangible equivalent, LASIK eye surgery is another form of vision correction.
