The eye can be analyzed with relative ease regarding both its function and its structure. A functional evaluation includes the ability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye may be evaluated in several ways. The client may be asked to determine illuminated letter or things of varying sizes on what is known as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye may be made in numerous methods. Tension within the eyeball is determined by a "tonometer." In particular illness, specifically in glaucoma, the stress in the eyeball is increased noticeably.
It needs to be well remembered that a patient with an eye issue may have other problems. Often other physical conditions are main and affect the eye as a repercussion. The appearance of the eye can inform the patient and the physician to difficulties in some disruptions of other parts of the body even before other signs present themselves.
Subsequently, one's reliance on sight is stressed when one deals with a short-lived or possible irreversible loss of this crucial sense. Hence, when corrective measures are sought, certain forms of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another type of vision correction. The only difference is that with this type of surgical treatment, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The main purpose of this surgery is to create a threadlike, rounded "flap" in the cornea utilizing a blade understood 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.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people should understand. Most likely, the main reason that this type of eye surgery has become well accepted is due to the fact that many of its cases had actually achieved success.
Nevertheless, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Since LASIK eye surgery involves the operation of the retina, which is one of the most sensitive portions of the eye, the majority of individuals say that the operation can be really risky.
Simply puts, a basic error could almost cause an individual's lifetime blindness. Hence, it is important to consider numerous elements prior to choosing whether LASIK eye surgery is the ideal corrective procedure one needs to go through.
2. It is not a best treatment
LASIK eye surgery may fix your vision but it does not necessarily mean that it can provide you a ideal vision. Even if statistical reports reveal that 70% of the patients might have 20/20 vision, this does not necessarily suggest they have ideal vision.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgery the way the majority of people view it
Alternatively, the examination of the structural part of the eye see may be made in a number of methods. It should be well remembered that a client with an eye issue might have other problems. Typically other physical conditions are main and impact the eye as a consequence. The look of the eye can alert the physician and the patient to problems in some disruptions of other parts of the body even before other signs provide themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction.
