Bifocal Lens Implants at Weinstein Refractive Center

Bifocal lens implants are a new and exciting part of cataract surgery and can also be implanted on their own during a process called refractive lens exchange. They work like the bifocal glasses of yesteryear, but are implanted in the eye and remain there with no required maintenance. Implantation is simple — bifocal lens implants are designed to be folded and implanted through a tiny, self-sealing incision. If necessary, lens implants can be removed or replaced at any time.

At Weinstein Refractive Center, we offer many types of lens implants: Crystalens®, ReSTOR® and ReZoom™. Both are excellent for patients with cataracts, though Crystalens® and ReZoom™ can also be implanted in patients with presbyopia (the loss of up-close visual acuity that comes with age). Each lens implant has distinct advantages, and we urge you to get acquainted with each type if you are one of the many sufferers of cataracts or presbyopia.

Refractive Lens Exchange

Refractive lens exchange is available for patients who prefer not to have LASIK correction. Patients who are presbyopic (require reading glasses only) can have a lens exchange and eliminate the need for glasses.


For people who are age 50 and older, the Weinstein Refractive Center now offers the first and only FDA-approved accommodating intraocular lens: Crystalens®. Contact us to find out if you are a candidate. The amazing Crystalens® technology allows you to always be in focus, delivering vision quality without compromise. And you do not have to sacrifice near or intermediate vision!

In order to focus on things, your human lens is moved by the ciliary muscles. Crystalens® moves the same way. The lens sits in the back part of the eye to accommodate distance vision. To facilitate intermediate vision, it gently flexes forward. For near vision, the lens flexes even further. This movement occurs because of the flexible hinges in the lens. Crystalens® mirrors the function of a natural lens by working with the eye’s muscle, contracting and adjusting to accommodate near, intermediate, and distance vision.

Due to the flexibility of the Crystalens® implantable lens, most patients are able to read a paper without glasses, as well as focus on objects at arm’s length, such as computer screens and dashboards. Distance vision isn’t compromised, so one can still see the TV set without putting on glasses.

The usual Crystalens® procedure takes less than 15 minutes. It is done on an ambulatory basis, with topical anesthesia and sedation. Patients are up and about the same day. Of course, no procedure is perfect and without complications or risks. Occasionally, the Crystalens® procedure requires fine tuning with LASIK or surface laser treatments. As an expert LASIK surgeon, Dr. Weinstein is able to bundle any follow up laser procedures with the original Crystalens® procedure without any price increases. It behooves any person considering Crystalens® to have an expert in cataract surgery with extensive experience using Crystalens® as well as years of laser refractive experience. A complete discussion of risk will be included in the full preoperative evaluation.®


The AcrySof® ReSTOR® multifocal lens implant can be used to correct cataracts, presbyopia, or both. This lens utilizes a technology called apodized diffraction, which allows patients to see well up-close as well as at a distance.

This tiny lens also has the advantage of filtering both UV and blue light. UV light can damage the eyes, and blue light has been associated with retinal damage, macular degeneration and vision loss. 

The ReSTOR® lens is designed to be folded and inserted into the eye through a small incision. The lens gently unfolds and remains in place by its supporting arms, which do not interact with any of your eyes’ structures.

In clinical trials, 80 percent of patients who received the ReSTOR® lens implant reported that they never had to wear glasses or bifocals. The ReSTOR® implant enjoys a high degree of success, patient satisfaction, and safety. If your natural lenses have been compromised by cataracts or presbyopia, ReSTOR® or ReZoom™, covered below, can be the key to sharp, hassle-free vision.


Like ReSTOR®, ReZoom™ is an intraocular lens implant that is particularly useful when implanted at the time of cataract surgery, but can also be implanted during refractive lens exchange to address presbyopia.

The advantage of ReZoom™ is that it provides excellent vision at many distances –close, far, and in between. Its design incorporates two lenses into one: a refractive lens for distance vision, and another for up-close vision. The lens distributes light over five optical zones.

ReZoom™ has excellent clinical outcomes, with more than 90 percent of patients wearing glasses either never or only occasionally following their surgery.

The Advantages of Intraocular Lens Implants

Crystalens®, ReZoom™ and ReSTOR® multifocal lens implants provide freedom from glasses or contacts to older patients suffering from cataracts or presbyopia. Lens implants have the advantages of bifocals with none of the inconveniences. They are invisible to others once implanted, stay in place with no special care, require no maintenance, and can be removed by a surgeon if necessary (for example, if your vision changes following surgery).
