Premium IOLs

During cataract surgery, artificial lenses are implanted in the eye to replace the cloudy natural lenses. These artificial lenses, known as intraocular lenses (IOLs), were once only able to correct distance vision, leaving patients dependent on eyeglasses or contact lenses for near vision. Many cataract patients, in addition to suffering from either nearsightedness or farsightedness, also suffer from presbyopia, natural changes to the eyes that occur as we age.

Before premium lenses, patients were unable to see clearly at both near and far distances without the use of eyeglasses or contact lenses. Early lens implants were monofocal, meaning that they had only one focal point and could not adjust to varying distances.

New advances in technology have allowed for the development of multifocal IOLs, which let patients see clearly at all distances, and can even correct astigmatism as well. Premium lens implants are ideal for cataract patients who are also suffering from presbyopia and want a replacement lens that provides a full range of clear vision.

There are several different types of premium lens implants available for cataract patients. Dr. Dangles will work with you to decide which lens is best for your individual eyes to help you enjoy long-lasting, clear vision at near, intermediate and far distances.  Contact us for an appointment to discuss Cataract  treatments at our office.


ReSTOR, short for AcrySof® ReSTOR® Apodized Diffractive Optic Posterior Intraocular Lens, replaces the natural lens removed because of cataracts. It has a patented optic design that combines apodized diffraction and refraction technologies for quality vision at both near and far distances. The apodized diffractive optic design gives it the ability to focus light correctly on the retina for images at various distances without mechanical movement of the lens.

Apodization is the gradual reduction or blending of the diffractive steps from the center to the outside edge of a lens; it creates a smooth transition of light between the distant, intermediate, and near focal points. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. The center of the ReSTOR lens surface consists of an apodized diffractive optic. This means that the series of tiny steps in the center area work together to focus light for near through distant vision.

Refraction involves the redirection of light passing through the lens to focus on the retina. The refractive region of the ReSTOR lens bends light to a focal point on the retina. This outer region – surrounding the apodized diffraction center – focuses light for distant vision.

Toric IOL

Toric IOLs are specially designed to correct astigmatism along with overall vision during cataract surgery, offering complete vision correction.

Before Toric IOLs, people with astigmatism would need to undergo corneal refractive surgery after their lenses were implanted, or would remain dependent on glasses or contact lenses. The advanced Toric IOLs correct the imbalance caused by an irregular cornea shape in patients with astigmatism. There are several different types of FDA approved Toric IOLs, including AcrySof® Toric Lenses, which can correct up to 3 diopters of astigmatism.

The risks of a Toric IOL include poor vision as a result of the lens rotating out of position, although this risk exists with any type of intraocular lens. Toric IOLs are considered safe for most patients with astigmatism and are the only solution to correct vision problems associated with both cataracts and astigmatism.
