Premium Lens Implants
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. Using apodization, diffraction and refraction technologies, the ReSTOR® lens improves upon ordinary replacement lenses (IOLs) by providing comprehensive focusing capabilities so patients can see clearly in a range of lighting conditions and at all distances -- at noon or midnight, nearby or far away, and many distances in between. Up to 80% of patients who use the ReSTOR® lens don't need to rely on glasses or contact lenses after surgery.
The FDA-approved AcrySof ReSTOR® is a major breakthrough in intraocular lens technology that can restore the eyesight of youth after cataract surgery.
How does it work?
When an eye develops a cataract the natural lens of the eye becomes clouded. This cloudy lens is removed with surgery and replaced with an implant. The AcrySof ReSTOR® implant has a patented optic design using apodization, diffraction and refraction technologies, thus giving it the ability to focus light correctly on the retina for images at various distances. The result is a high level of glasses-free vision after cataract surgery.
When is it used?
The AcrySof ReSTOR® IOL is used in adult patients who desire near, intermediate and distance vision with increased independence from glasses following cataract surgery.
Clinical data demonstrates that AcrySof ReSTOR® IOL greatly reduces dependence on glasses or bifocals:
- 80% of patients reported that after lens implant surgery with ReSTOR lenses, they never needed glasses or contact lenses to see clearly at all distances.
Results from a controlled clinical study of the AcrySof ReSTOR® IOL revealed that maximum visual performance is achieved when the lens is implanted in both eyes.
In addition, the quality of vision compared to wearing bifocals and/or trifocals is significantly improved. You'll have a full range of vision, without having to tilt your head to find that portion of your glasses that allows you to see clearly.
Would I benefit from the ReSTOR lens?
If you have cataracts, your doctor will discuss the benefits of this new technology with you during your next appointment.
Toric (astigmatic) IOL
Intraocular lenses are used during cataract surgery to replace the damaged lens of the eye with an implant that clears up and corrects vision, oftentimes leaving patients with little to no dependence on glasses.
Up until now, patients with astigmatism did not have the same opportunities that other cataract patients have had in correcting their condition with the types of IOL lenses that were available. Typically, the astigmatic patient would need an additional surgical procedure, such as refractive surgery or LASIK, to correct their vision after the procedure. If the patient did not want to undergo another surgical procedure, the only option for correction would be the use of either contact lenses or glasses to address their astigmatism.
Toric IOLs are able to accommodate for the condition of astigmatism. Toric IOLs are specially designed to correct astigmatism along with overall vision during cataract surgery, offering complete vision correction.
Benefits of a Toric IOL
The advanced Toric IOLs correct the imbalance caused by an irregular cornea shape in patients with astigmatism. The benefit of a Toric IOL is to reduce the dependency of glasses after Cataract Surgery.
To see if you are a Toric IOL candidate please ask your doctor at your next appointment or schedule consultation.
