HOME PROCEDURES PREMIUM LENS IMPANT

DID YOU KNOW?

Until fairly recently, only monofocal (one focal distance) lenses were available for those needing cataract surgery. Newer multifocal lens implants and accommodating intraocular lenses now offer a range of focusing distances.

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

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.

Presbyopia

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.

Now, there are a couple of options available: Multifocal Lens Implant and Accommodating Intraocular Lenses. These lenses offer a range of focusing distances rather than the single point of focus of traditional lenses.

a) Multifocal Lens Implant

Most people are aware of bifocal glasses, or even progressive lenses (no-line bifocals). 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.

BoydVision offers three different options for this type of implant:


They are all made with concentric rings to enable focusing on near and far objects. These are the best lenses to achieve reading vision but the "rings" can produce night halos which occasionally are noticeable with night driving.

b) Accommodating Lens Implant

This lens (Crystalens Implant) works most similarly to the natural human lens – bending inside the eye to adjust focus for reading. As apposed to the Multifocal lens implant it doesn't have rings and therefore has excellent night vision but achieves less near vision.
