The eye can be examined with relative ease as to both its function and its structure. A functional evaluation consists of the ability to relocate the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be evaluated in several ways. The patient might be asked to determine illuminated letter or things of differing sizes on exactly what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye may be made in a number of ways. Stress within the eyeball is determined by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased significantly.
It must be well kept in mind that a client with an eye problem may have other problems. Frequently other physical conditions are main and affect the eye as a consequence. The appearance of the eye can inform the physician and the client to difficulties in some disturbances of other parts of the body even before other symptoms provide themselves.
One's dependence on sight is stressed when one faces a possible or short-term irreversible loss of this important sense. Hence, when restorative steps are sought, particular kinds of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some individuals are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgical treatment is another form of vision correction. The only distinction is that with this type of surgery, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently 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 lastly reformed, enabling much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people must understand. Probably, the main reason this type of eye surgical treatment has become well accepted is since the majority of its cases had succeeded.
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
Because LASIK eye surgery includes the operation of the retina, which is one of the most sensitive parts of the eye, many people say that the operation can be very risky.
In other words, a easy mistake could practically trigger an person's lifetime blindness. Hence, it is necessary to think about lots of elements before deciding whether LASIK eye surgical treatment is the best restorative step one needs to undergo.
2. It is not a perfect procedure
LASIK eye surgical treatment might fix your vision however it does not always indicate that it can provide you a best vision. Even if analytical reports reveal that 70% of the clients may have 20/20 vision, this does not always mean they have perfect vision too.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the perfect eye surgery the way the majority of people see it
Conversely, the assessment of the structural part of the eye may be made in several ways. It needs to be well kept in mind that a patient with an eye problem may have other problems. Often other physical conditions are main and affect the eye as a consequence. The look of the eye can alert the patient and the doctor linked here to difficulties in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Like its tangible equivalent, LASIK eye surgery is another kind of vision correction.
