Crystalens™ is a new cataract replacement lens (IOL) that works naturally with focusing muscle in the eye to retain the eye's ability to “accommodate” – shift it's focus between nearby and distant objects – after cataract surgery. With other IOLs, patients lose this ability and require corrective measures such as glasses or contact lenses.
 Unlike rigid lenses, the flexible silicone Crystalens™ features hinges that allow it to move or flex with the eye's focusing muscle and accommodate seamlessly, thereby reducing or eliminating the need for vision correction.
The Crystalens™ is implanted using the same, small incision, no-stitch cataract surgery techniques as with other IOLs. The patient should expect an adaptation period after surgery during which the patient “learns” to use the new implant.
 Patients who are far-sighted, or who have bilateral cataracts or who have had corneal refractive surgery and retained good eye health are acceptable candidates for Crystalens™ implantation. Even some patients who have already had cataract surgery in one eye can have a Crystalens™ implant in their other eye People with eye health problems such as chronic infections or diabetes should check with their doctors about eligibility.

 The ReZoom™ multifocal intraocular lens (IOL) helps patients focus clearly on objects at a range of distances and in varied light conditions, so they can be free of glasses or contact lenses after cataract surgery. The ReZoom™ lens features five spherical segments with smooth transitions in between so the eyes focus seamlessly from one distance to the next. The center of the lens is optimized for bright light and distance vision, while the fourth zone supports near-vision in a variety of light conditions, and the outermost zone accommodates for low-light distance vision (such as when driving at night). The ReZoom™ is also specially designed to reduce internal reflections and minimize glare.

 Physicians have been using flexible IOLs for years to replace the eye's cloudy lens during cataract surgery and help patients enjoy clear vision again. The ReSTOR® lens improves upon the ordinary IOL by using apodized diffractive technology to provide a full range of focusing distances from near to far. A series of 12 gradual "step heights" of 0.2-1.3 microns each (thinner than a human hair and smaller than a red blood cell) in the center of the IOL create seamless focusing ability, while the peripheral refractive region helps to enhance distance vision. Apodization also allows the lens to work with the pupil to distribute light evenly in the eye in different lighting conditions and activity levels. Alcon® reports that up to 80% of patients who use the ReSTOR® lens don't need glasses after surgery.

Many patients have suffered with astigmatism their whole life. They have been told they could not wear contacts, or needed to buy expensive lenses for their glasses. And they were told there was nothing that could be done to correct this problem. That is no longer the case.
Astigmatism is an optical defect in your visual system, such that the focusing power of your eye is not symmetrical and the same in all meridians.
Light refracted to multiple areas of the retina
This causes a constant blurring of the visual image your brain is seeing. Astigmatism can exist separately or be combined with near-sighted or far-sightedness.
Dr. Witlin has been successfully using the Alcon Toric Lens Implant to help his patients to permanently get rid of their astigmatism and enjoy clearer uncorrected vision than they have ever experienced. Based upon the excellent results he has been achieving and the high level of patient satisfaction, he is recommending this type of implant to many of his astigmatic cataract patients.
The Toric Lens Implant is used in place of a conventional lens implant at the time of cataract surgery. Patients with this implant can usually see clearly for distance activities such as TV or golf, without the need for glasses or contacts.
There are minimal side-effects to using this lens implant in selected patients. The risks are essentially the same as using a conventional implant, without any increased chance of glare or halos.
There is an increased cost for these lenses that is paid by the patient and not by their health insurance.
