What is the crystalens® accommodative intraocular lens?
The crystalens accommodating intraocular lens is an intraocular lens used after cataract surgery or as a lens alternative in presbyopic lens exchange. The concept of the lens was engineered with a hinge design to allow the optic, or part of the lens that you see through, to move back and forth as your focus on an image changes. The crystalens® accommodative intraocular lens is permanently implanted with a surgical process and functions in a similar fashion as the natural eye. Once the surgery has been completed your eyes can focus on far or near objects in a comfortable way. If you are experiencing presbyopia or cataracts please feel free to consult us about the possibility of utilizing the new crystalens® accommodative intraocular lens.
HOW DOES THE crystalens® IOL WORK?
After the age of 40 people will often start to experience difficulty reading as the eye’s natural lens starts to harden. Prior to this many people often experience excellent vision and are typically confused as to what is happening with their eyes.
Because their vision may have been perfect they have never consulted an ophthalmologist as to what is naturally occurring. This inability to see at close distances or difficulty for the muscles in the eye to auto-focus can be very discouraging. This is known as loss of accommodation, or presbyopia. The crystalens was engineered with a hinge design to allow the optic, or part of the lens that you see through, to move back and forth as your focus on an image changes.
FDA Clinical Trial Information
- 98.4% of patients implanted with crystalens in both eyes could pass a driver's test without glasses
- 100% could see intermediate (24" to 30") without glasses, the distance for most of life's activities
- 98.4% could see well enough to read the newspaper and the phone book without glasses.
Some patients did require glasses for some tasks after implantation of the crystalens
Significantly more patients implanted with a crystalens (88.4%) could see better at all distances then patients implanted with a standard IOL (35.9%)
Frequently Asked Questions
How long does it take to heal?Each patient is unique and the healing process will be different in each case. Most patients return to their normal work or lifestyle in two to three days. The focusing ability of the lens will not be fully realized for 6 to 8 weeks after the procedure. The eye must re-learn how to focus on objects at various distances in order to see clearly. It is important to discuss your expectation for this lens with your surgeon so that you can better understand the actual healing process.
Can my vision be corrected to 20/20, for both reading & distance?The crystalens has been designed to focus your eyes at all distances after cataract surgery. While virtually everyone will experience a significant improvement in their uncorrected vision after surgery, some people will not see 20/20 at all distances. It is interesting to note that many people who have not had surgery are not able to see 20/20 at both near and far even with glasses or contact lenses. This is due to a variety of ocular and physiological problems as well as lifestyle preferences, yet most of these people function quite normally although their vision is reduced. The two-year clinical trial that supported the FDA approval of the crystalens indicated that 92% of the people enrolled in the study (implanted bilaterally) could see 20/25 or better at distance, 96% could see 20/20 at arm’s length and 73% could see 20/25 at near without glasses or contact lenses. What is more exciting is that 98% of these people could pass their drivers test, 100% could see their computer and dashboard, read the prices in the supermarket or put on their makeup, and 98% could read the telephone book or newspaper, all without glasses or contact lenses. It is important to keep in mind that visual acuity is subjective and depends upon each individual’s own ocular and physiological conditions as well as lifestyle preferences. Some patients implanted with the crystalens still require glasses for certain activities. (Courtesy of www.crystalens.com)
What makes the crystalens different from other intraocular lenses?The crystalens has the unique ability to focus on objects at varying distances using the eye’s natural focusing system. This means that the crystalens can provide a continuous range of vision, without corrective lenses, from near to far and everything in between. Standard (single vision) lens implants do not have the ability to provide a full range of vision. Most people who have single vision lens implants MUST wear glasses for middle and near vision. It was shown in the two year clinical trial that supported the FDA approval of the crystalens that significantly more patients implanted with a crystalens (88%) could see better at all distances than patients implanted with a standard lens (36%).
