Lifestyle Lens Options
Say Goodbye to Cataracts and Astigmatism
For cataract patients with astigmatism, successful cataract surgery is only half the battle for regaining quality vision.Until recently, the only viable vision correction options for astigmatism correction after cataract surgery were eyeglasses or contact lenses, both of which are not only inconvenient in terms of lifestyle but can also be expensive over your lifetime. The AcrySof® Toric Intraocular Lens (IOL) is an advanced technology that now makes it possible to correct the cataracts clouding your vision AND the corneal astigmatism distorting your vision — all at the same time.
Who is AcroySof IQ Toric lenses for?
Many patients have been forced to wear glasses for most of their lives because of astigmatism. A normal cornea is more rounded like a basketball. Light rays pass through, bend toward the center and focus on one spot. Patients with astigmatism do not experience quality distance vision. Unfortunately the shape of their cornea is more curved such as a football, with both a flatter and steeper surface. When light rays pass through an astigmatic eye, vision becomes distorted. Toric lens implants are designed for individuals with significant astigmatism who would like to reduce their dependence on glasses after cataract surgery. These lenses are highly effective at reducing astigmatism and most patients, post-surgery, can function well for distance activities without glasses. These lens implants do not provide near focus and reading glasses are still needed for viewing at near after surgery.
If you depend on eyeglasses, you may have experienced the inconvenience of not being able to find your glasses when you really need them. Glasses are easily lost or damaged. The more active you are, the more glasses can sometimes interfere with your lifestyle. If freedom from glasses for distance vision is important to you, you now have a better option! The unique design of the Acrysof Toric lens provides significantly improved distance vision and may reduce the need for corrective lenses after surgery. The vast majority of Dr. Kutryb’s patients once receiving the Acrysof toric lens, only require reading glasses for up-close work. This is a wonderful trade off compared to requiring glasses all of the time.
What is Crystalens?
Crystalens is an accommodating intraocular lens that, unlike a standard IOL, can treat both a person’s cataracts and presbyopia—loss of near and intermediate vision. You probably noticed in your forties that you started to lose some of your up-close vision and had to start wearing reading glasses. Crystalens not only treats your cataracts (a clouding or hardening of your lens), but can also reduce or eliminate your dependence on glasses. It does so by recreating accommodation similar to your eye’s natural lens. The unique Crystalens can reduce or eliminate glasses for most activities, including: reading a book, working on the computer, and driving a car.
Crystalens was modeled after the human eye. Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances. Crystalens dynamically adjusts to your visual needs. When the muscle contracts it bulges backwards and increases pressure behind the lens, thus forcing the optic forward. Relaxation of the muscle increases the pressure in front of the lens to move the optic backwards, thus enabling the lens to focus naturally at all distances.
ONLY FDA-Approved Accommodating IOL
Crystalens was the first presbyopia correcting IOL introduced into the United States market and is currently the only FDA-approved accommodating IOL. Crystalens addresses the limitations of standard monofocal IOLs and multifocal IOLs by providing the following advantages to patients:
Provides a Broad Range of Vision
Crystalens moves and changes shape using the eye’s natural focusing mechanism, instead of remaining fixed and stationary within the eye. This movement, or accommodation, allows the eye to focus on objects across a broad range of distances to reduce or eliminate dependence on glasses. In particular, this accommodation provides significant advantages in addressing intermediate vision.
Maintains Clarity of Vision
Unlike multifocal lenses, Crystalens directs all available light received by the eye to a single focal point, comparable to that of a healthy natural lens.
Patient Adjustment Not Required
Crystalens produces a single image consistent with normal vision, meaning patients do not need to neuroadapt to viewing multiple images. Patients also do not need to tolerate or adjust to high levels of halos and glare often associated with multifocal IOLs.
Crystalens is designed to allow the optic, or the central circular part of the lens that you see through, to move back and forth as you constantly change focus on images around you. Crystalens flexes as you focus your vision.
