The eye can be analyzed with relative ease regarding both its function and its structure. A functional assessment includes the capability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye might be evaluated in numerous ways. The client might be asked to identify illuminated letter or items of differing sizes on what is referred to as the Snellen chart.
Conversely, the evaluation of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased markedly.
However, it must be well kept in mind that a patient with an eye problem might have other issues too. Often other physical conditions are primary and affect the eye as a repercussion. The look of the eye can signal the patient and the physician to troubles in some disruptions of other parts of the body even prior to other signs present themselves.
Consequently, one's dependence on sight is emphasized when one faces a momentary or possible irreversible loss of this important sense. When restorative steps are sought, certain forms of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are bothered with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to motivate reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another kind of vision correction. The only distinction is that with this type of surgery, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The primary purpose of this surgical treatment is to produce 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, permitting much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to know. Most likely, the main factor why this type view it now of eye surgical treatment has ended up being well accepted is because the majority of its cases had achieved success.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Since LASIK eye surgery includes the operation of the retina, which is among the most sensitive parts of the eye, many people state that the operation can be very risky.

2. It is not a best treatment
LASIK eye surgical treatment might correct your vision but it does not necessarily imply that it can offer you a twenty-twenty. Even if statistical reports show that 70% of the clients might have 20/20 vision, this does not necessarily indicate they have ideal vision too.
Offered 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 method most people see it
Alternatively, the examination of the structural part of the eye may be made in numerous methods. It must be well remembered that a patient with an eye issue may have other issues. Typically other physical conditions are main and see this impact the eye as a consequence. The look of the eye can inform the physician and the client to troubles in some disturbances of other parts of the body even prior to other symptoms provide themselves.
