New Multifocal Lens Implants
You can NOW enjoy the benefits of improving both near vision and far vision after cataract surgery! We offer our patients options for multifocal lens implants after cataract surgery to reduce dependence on glasses.
Cataract Surgery

Cataract surgery has enjoyed many significant improvements in recent years as a result of advances in technology and refinements in surgical technique. This has resulted in safer surgery with more rapid visual recovery, better visual results, and fewer complications.

Contrary to popular belief, cataracts are generally not removed with lasers. The technique most commonly used today is phacoemulsification in which a hollow needle delivers high energy sound waves to the cataract in order to break it up into very small particles which are in turn washed out. All this takes place through a small self-sealing incision which usually requires no suture to make it secure. (Understandably, this technique is readily confused with laser because of the sophisticated nature of both technologies.) The typical cataract incision now measures approximately 2.5 - 3.0 millimeters. The advantages of small incision surgery include minimal or no induced astigmatism as well as a rapid return to full activities. Microprocessors help control the important balance between fluid and emulsified cataract material being removed from the eye and the fluid that is used to replace it. Maintaining a stable volume within the compartments of the eye during surgery gives the surgeon better control and makes for a safer and speedier operation.

The benefits of removing a cataract through a small incision are lost if the incision must then be enlarged for implanting the intraocular lens. This is where foldable intraocular lenses play a role. By folding or scrolling a 6.0 millimeter diameter implant into a much narrower shape, it can be inserted or injected through a 3.0 millimeter incision using a specially designed tube-like cartridge and then allowed to unfold to its full diameter once inside the eye.

Why bother with an intraocular lens implant in the first place? Remember that a cataract is the human lens turned cloudy, and that by removing it, an essential optical element of the eye would now be absent. Before the era of intraocular lenses, the eye would need a contact lens or a thick "Coke bottle" eyeglass lens in order to restore clear vision after a cataract operation. These thick lenses produced large amounts of distortion, and have virtually become a thing of the past.
