The eye can be taken a look at with relative ease as to both its function and its structure. A functional assessment includes the ability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye might be evaluated in a number of ways. The client may be asked to identify illuminated letter or objects of differing sizes on exactly what is called the Snellen chart.
On the other hand, the assessment of the structural part of the eye might be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased significantly.
However, it must be well kept in mind that a patient with an eye issue might have other problems as well. Often other physical conditions are main and affect the eye as a effect. The appearance of the eye can notify the doctor and the client to troubles in some disturbances of other parts of the body even prior to other signs provide themselves.
As a result, one's dependence on sight is stressed when one faces a possible or short-term irreversible loss of this vital sense. When corrective steps are looked for, particular kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are troubled with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were developed to motivate decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, 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 kind of surgical treatment, one's vision is fixed 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 called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing appeal of LASIK eye surgery, there are still disadvantages that people should know. Most likely, the main reason that this type of eye surgery has ended up being well accepted is due to the fact that the majority sites of its cases had actually achieved success.
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
Due to the fact that LASIK eye surgery involves the operation of the retina, which is one of the most sensitive portions of the eye, many people state that the operation can be extremely risky.
In other words, a simple mistake might almost cause an person's lifetime blindness. It is important to think about lots of elements prior to choosing whether LASIK eye surgical treatment is the ideal restorative measure one has to undergo.
2. It is not a best procedure
LASIK eye surgery may fix your vision but it does not always mean that it can give you a perfect vision. Even if statistical reports reveal that 70% of the patients may have 20/20 vision, this does not necessarily mean they have perfect vision too.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the perfect eye surgery the way the majority of people see it
Alternatively, the assessment of the structural part of the eye may be made in numerous ways. It must be well kept in mind that a patient with an eye issue might have other issues. Often other physical conditions are main and impact the eye as a effect. The appearance of the eye can signal the doctor and the client to difficulties in some disturbances of other parts of the body even prior to other signs provide themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another form of vision correction.
