The eye can be examined with relative ease as to both its function and its structure. A functional assessment consists of the capability to move in the orbit and the reaction of the student to light and lodging.
The function of the eye may be checked in a number of ways. The patient might be asked to determine illuminated letter or things of differing sizes on what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in several methods. Stress within the eyeball is measured by a "tonometer." In particular illness, especially in glaucoma, the tension in the eyeball is increased markedly.
It ought to be well remembered that a patient with an eye issue may have other issues. Often other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can alert the doctor and the client to troubles in some disruptions of other parts of the body even prior to other signs provide themselves.
Subsequently, one's reliance on sight is highlighted when one deals with a possible or momentary permanent loss of this important sense. Hence, when restorative steps are sought, certain forms of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another form of vision correction. The only difference is that with this type of surgical treatment, one's vision is corrected completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely transformed. This can be done utilizing an "excimer laser."
The main purpose of this surgical treatment is to create a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, allowing better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to understand. Probably, the primary reason this type of eye surgery has actually become well accepted is due to the fact that the majority of its cases had succeeded.
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 anchor fact that LASIK eye surgical treatment includes the operation of the retina, which is one of the most sensitive portions of the eye, many people say that the operation can be very dangerous.
In other words, a simple mistake might practically cause an individual's life time blindness. For this reason, it is essential to think about many aspects before choosing whether LASIK eye surgery is the ideal restorative procedure one needs to undergo.
2. It is not a ideal procedure
LASIK eye surgical treatment might remedy your vision but it does not necessarily indicate that it can offer you a twenty-twenty. Even if statistical reports reveal that 70% of the patients might have 20/20 vision, this does not always suggest they have ideal vision as well.
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 many people see it
Conversely, the assessment of the structural part of the eye may be made in several ways. It must be well kept in mind that a patient with an eye problem might have other problems. Typically other physical conditions are main and affect the eye as a effect. The look of the eye can notify the patient and the physician to problems in some disturbances of other parts of the body even prior to other symptoms present themselves.
