VISION DISORDER

REFRACTIVE DYNAMICS

MYOPIA
(nearsightedness or shortsightedness):

This condition results in light focusing in front of the retina. Individuals with myopia see near objects clearly, but distant objects are blurry.

HYPEROPIA
(farsightedness):

This disorder results in light not focusing by the time it reaches the retina. For farsighted individuals, distant objects are blurred and near objects are even more blurred.

ASTIGMATISM:

This occurs when the cornea is oval shaped, like an egg or football. In this condition light is bent unequally, forming two focal points and preventing a clear image from forming on the retina. One may have astigmatism alone or in combination with myopia or hyperopia.

PRESBYOPIA:

As we perform our daily activities such as reading, watching television, and driving, our eyes are constantly focusing on objects at varying distances.  This process is called accommodation and diminishes slowly after age 45.  The reduction in accommodation is known as presbyopia. The reason for presbyopia is that the lens of the eye loses flexibility, and the ciliary body muscle surrounding the lens weakens.  Most people wear reading glasses or bifocals when they have presbyopia.

PROCEDURE

USED FOR

1. LASIK

1. Myopia (nearsightedness).
2. Hyperopia (farsightedness).
3. Astigmatism

2. PRK/EPI-LASIK

Read more about PRK/EPI-LASIK

1. Non-candidates for LASIK because of thin, flat, steep, or irregular corneal shape. (Up to 10 diopters of myopia and 5 diopters of hyperopia).
2. Also for people with moderately dry eye.
 

3. PHAKIC IMPLANT

(with natural lens in place)

1. Non-candidates for laser vision correction because of very high levels of myopia.

4. NON-PHAKIC IMPLANT/CLEAR LENS EXTRACTION

(with natural lens removed)

1. Non-candidates for laser vision because of high levels of hyperopia.
2. Treatment of presbyopia.
