A graphic animation of what causes fat and sagging eyelids. The video describes what takes place during eyelid surgery (blepharoplasty).

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.

This narrated animation explains the goals and benefits of eyebrow surgery or blepharoplasty. It also describes the possible surgical approaches used in blepharoplasty.

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.

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.

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.

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.
