Cataract Surgery Vision Correction

This animation depicts modern cataract surgery with phacoemulsificaiton of the lens and IOL implantation.

That said, recently, laser cataract surgery was approved by the FDA. This vision correction procedure does not actually use a laser to remove the cataract but many of the traditional steps in cataract surgery are performed with a femtosecond laser.

Cataracts are the leading cause of visual loss in adults age 55 and older and the leading cause of blindness worldwide. By age 65, most people will develop a cataract. Cataracts are very successfully treated in the United States and through advances in both cataract surgery and intraocular lenses (IOLs), more people are gaining back useful vision through cataract surgery.

Recent advances in laser technology have led to the development of a new laser surgery technique for treating cataracts known as femtosecond laser surgery.

What is a cataract?

A cataract affects the lens of the eye. The lens is normally clear, but with age and certain eye conditions, a cataract can develop, causing the eyesight to become blurry, as light cannot pass through the lens correctly. Cataracts can develop in one or both eyes. The cloudier the lens, the worse the vision and the greater the need for cataract surgery.

Cataract surgery

In traditional cataract surgery, an incision is made with a steel blade or a diamond knife. The pieces of lens are then removed. Afterwards a new lens (intraocular lens) is put in to replace the old. Cataract surgery is one of the safest surgeries to be sure, but the precision at which it can be done depends on the surgeon’s skill.

Removing the cataract involves creating an opening in the extremely thin membrane (capsule) that covers the natural lens of the eye.  Traditional methods using handheld surgical tools are generally safe but the new femtosecond laserprocess has been shown to be more accurate by far in over 90% of all cases studied.

Mark Erickson

Working as an Ophthalmic Photographer since 1988, Mark Erickson has examined and photographed virtually every type of eye condition there is through various high-powered microscopes and cameras. This experience has given him a unique and intimate understanding of the eye and its various anatomical structures, diseases and surgical procedures. In 1998, Mark started coupling this medical photography experience with his artistic and creative abilities. The result is a vast gallery of various eye anatomy, eye conditions & diseases and surgical illustrations. Mark’s work has been published on the front cover of numerous, top eye care industry magazines and books. His work frequently illustrates the front cover of industry journals. Mark’s work has been commissioned by National Geographic, Bausch & Lomb, Johnson & Johnson and Transition Lenses, to name a few. Mark Erickson’s artwork and story were published in The National Association of Photoshop Professionals monthly publication, “Photoshop User” and “Layers” magazines. Mark now focuses his creative energy on his website,, and creating and licensing stock and custom ophthalmic illustrations and animations for use in pharmaceutical marketing, legal cases, product marketing, websites and patient education materials.
