The eyes are your body’s most highly developed sensory organs. In fact, a far larger part of the brain is dedicated to vision than to hearing, taste, touch, or smell combined! We tend to take eyesight for granted; yet when vision problems develop, most of us will do everything in our power to restore our eyesight back to normal.
The most common forms of vision impairment are errors of refraction — the way light rays are focused inside the eye so images can be transmitted to the brain. Nearsightedness, farsightedness, and astigmatism are examples of refractive disorders and often occur when the eyes are otherwise healthy. Refractive errors are correctable usually with glasses, contact lenses, or refractive surgery.
Other vision problems may be related to eye disease. Retinal detachment, macular degeneration, cataracts, and glaucoma are disorders of the functional eye and its processing units. These problems can lead to blurry or defective vision. The goals of treatment depend on the eye disease and may include restoring vision, halting vision loss, and preserving remaining eyesight.
Here are descriptions of common vision problems and their treatments.
Nearsightedness, or myopia, affects nearly 30% of the population. It is the result of images being focused in front of the retina (where 10 layers of delicate nerve tissue make up the retina) rather than on it, so distant objects appear blurred. A nearsighted person whose eyesight has not been corrected holds a book closer to the eyes when reading and has to sit in the front of the classroom or movie theater to see clearly.
Farsightedness, or hyperopia, is the opposite of nearsightedness. The hyperopic eye focuses images slightly behind the retina, making nearby objects appear blurry.
Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye.
Vision problems diagnosis
Periodic comprehensive eye exams by an eye doctor are essential to monitor the health of your eyes and diagnose suspected problems. Checking the position of each eye and its movements will reveal crossed eyes or other forms of strabismus.
If routine testing indicates that you have a refractive error, conventional treatment calls for wearing corrective glasses or contact lenses. In many cases, surgical correction of refractive errors is possible using modern surgical techniques such as LASIK.
Conventional treatment for disorders such as nearsightedness, farsightedness, and astigmatism typically rely on corrective prescription lenses. Disorders such as cataracts, glaucoma, macular degeneration, and retinal detachment require advanced medical and surgical treatments. Enormous progress in eye surgery has been made over the past few decades.
The newest therapeutic approach to vision problems is the refined trans PRK method. This new technique, which is non-invasive, solves eye problems using laser energy. In the refined trans PRK Therapy, laser radiation is tailored to each individual patient, based on the physical characteristics and optical parameters of each individual. Due to the adaptation of the operating conditions to the patient’s condition, the treatment results have significantly improved.
