Premium Lens Implant

(Glasses Independence) There are two reasons to require glasses after cataract surgery. One reason is to correct astigmatism, and the other is to correct presbyopia. For individuals that would like to avoid having to wear glasses after cataract surgery, one or both of these must be addressed.

Astigmatism is a common condition that may cause blurred vision. The distorted vision is caused due to the eye’s cornea or lens having an irregular shape. Generally more than 1/3 of patients require glasses to correct astigmatism. With the new Toric Lens Implant this internal optical distortion of the eye can be neutralized. After surgery the patient will not need glasses except to read.


Around the age of 45, most people begin to have difficulties changing the focus in their eyes from distant objects to near vision tasks such as reading. For those who have never worn glasses, they will now need to begin using reading glasses. Those who already wear glasses may choose to get bifocals (or no-line bifocals known as progressive lenses). A small percentage of people are fortunate to have the right amount of nearsightedness to allow them to read without their glasses, even though they need them to see in the distance.

Until fairly recently, individuals who had cataract surgery had no real options in lens implants. Only monofocal (one focal distance) lenses were available. This means the eye can only focus at one distance.

Multifocal Lens Implant

Most people are aware of bifocal glasses or even progressive lenses. These types of glasses allow us to see distant and nearby objects in clear focus by looking through different parts of the lenses. When cataract surgery is done, a lens implant replaces the crystalline lens of the eye. It is now possible to use a multifocal lens implant.

There are multiple different options for this type of implant. We do the measurements and during a consult, we discuss lifestyle, vision requirements to determine which lens is the best choice for improving your vision and minimizing the need for glasses. The technician will discuss the pros and cons of the lenses. Together with Dr. Boyd, a decision will be made for the lens that best fits your lifestyle and vision improvement.
