How_Does_Laser_Eye_Surgery_Affect_The_Eyes_


In order to truly comprehend the effect of laser eye surgery, we must first consider the vision anomalies that it treats. It is a general belief that common refractive errors, such as myopia, hyperopia and astigmatism, are attributable to certain irregularities in the shape of the cornea. Due to such anomalies, light rays entering the eye don't fall exactly on the retina (a layer of light sensing cells) thereby resulting in unclear vision. LASIK is a surgical procedure that aims to rectify these irregularities by reshaping the cornea.

LASIK restores visual acuity through precise ablation of the corneal tissue with the aid of a high precision laser, an excimer laser, which is a 'cool' laser that precisely carves the cornea without heating or damaging the surrounding tissue. Once reshaped, the cornea enables the desired accurate refraction, since the light rays now fall precisely on the retina.

Laser eye surgery imparts enhanced visual acuity, without the need for corrective lenses. With the superlative technology at its disposal, laser eye surgery provides excellent results that are rather impressive. An estimated 98% of patients are within 1 diopter of their refractive error following surgery, possessing unaided visual acuity of 6/12 or better. Over half of the patients achieve unaided visual acuity of 6/6, which is the standard visual acuity. However, visual acuity may sometimes be worthless if vision quality is sacrificed in process. Though rare, laser eye surgery complications like halos, glare and double vision may cause vision quality deterioration, rendering blurry vision.

The complications, if any, may be a source of discomfort. The use of prescription eye drops and artificial tear drops helps in soothing the eyes thereby averting the irritable feeling in the eyes that creeps up after surgery. These side effects are known to subside within a few months and the refraction stabilizes within 3 to 6 months following surgery.

Nevertheless, LASIK is a viable, safe and efficacious procedure. Its effects are permanent on the eyes. That is, the refraction attained lasts forever unless otherwise altered due to age related eye ailments, such as presbyopia, which is known to affect almost every individual in their mid to late 40s.

Flax is a grain crop which has several substances that can be healthy. It has fiber, omega-3 fatty acids and lignans. You can add flax to your diet by either using the flaxseeds or flaxseed oil. Both will add the essential omega-3 fatty acid, alpha linolenic acid (ALA) to our bodies. We need this fatty acid and are unable to make it on our own. This fatty acid may help reduce the risk for cardiovascular disease and sudden cardiac death. It is believed that flax's fatty acids, as well as fiber, help in lowering blood cholesterol.

Flaxseed has been a part of human and animal diets for thousands of years in Asia, Europe, and Africa, and more recently in North America and Australia, says Kaye Effertz, executive director of AmeriFlax, a trade promotion group representing U.S. flaxseed producers. As flax gained popularity for its industrial uses, however, its popularity as a food product waned, but it never lost its nutritional value.

What does Flax Seeds look like?

Flax seeds are slightly larger than sesame seeds and have a hard shell that is smooth and shiny. Their color ranges from deep amber to reddish brown depending upon whether the flax is of the golden or brown variety. While whole flaxseeds feature a soft crunch, the nutrients in ground seeds are more easily absorbed.

Today flax is experiencing a renaissance among nutritionists, the health conscious public, food processors, and chefs alike!
