Any object that we see is a collection of light energy focused on the retina. The lens of the eye helps us see near and far things equally well. This animation describes how the lens of the eye changes to accommodate and focus light.

This provides a very detailed, step-by-step animation of how cataract surgery is performed. It also show how an intraocular lens or IOL is inserted after the natural lens is removed in the cataract surgery shown.

Physiology of the Cornea

Most laser vision correction procedures like LASIK involve shaping the cornea so that light can be properly focused on the back of the eye, or retina. This video shows how the anatomy of the eye works to harness light so that we can see. The role of the cornea in vision is also discussed.

Science Animation 16 - The Eye

This video shows how vision is dependent on light entering the front of the eye and focusing on the retina at the back of the eye. When this focus cannot be accomplished by the eye muscles or lens of the eye, it results in nearsightedness or farsightedness. Sometimes changes in the cornea can correct these errors of refraction.

How LASIK eye surgery is carried out

Crisp images from our world require that light is focused on the back of the eye. When light cannot focus properly, it is called an error of refraction and is often caused by an irregular or improperly shaped cornea. LASIK improved errors of refraction in the eye by reshaping the cornea, as the animation explains.

Normally intraocular fluid flows freely between the anterior and posterior sections of the eye (A). As pressure builds in the eye, this circulation is cut off (B). In laser iridotomy, a special lens is placed on the eye (C). A laser is used to create a hole in part of the iris (D), allowing fluid to flow more normally and intraocular pressure to return to normal (E). (Illustration by GGS Inc.)

Other Information

Laser iridotomy is a surgical procedure that is performed on the eye to treat angle closure glaucoma, a condition of increased pressure in the front chamber (anterior chamber) that is caused by sudden (acute) or slowly progressive (chronic) blockage of the normal circulation of fluid within the eye. The block occurs at the angle of the anterior chamber that is formed by the junction of the cornea with the iris. All one needs to do to see this angle is to look at a person's eye from the side. Angle closure of the eye occurs when the trabecular meshwork, the drainage site for ocular fluid, is blocked by the iris. Laser iridotomy was first used to treat angle closures in 1956. During this procedure, a hole is made in the iris of the eye, changing its configuration. When this occurs, the iris moves away from the trabecular meshwork, and proper drainage of the intraocular fluid is enabled.

Other Information

Surgeons aim for results of 20/20 or better so that you can perform most daily activities without your glasses. However, there is a possibility that after surgery, you may need to wear reading glasses or corrective lenses for at least some activities.
