San Diego Rezoom Cataract Surgery / ReStor IOLs Specialist - Dr. Angela Nahl

Dr. Angela Nahl is a talented San Diego cataracts surgeon dedicated to helping patients realize their vision correction goals. She specializes in cataract surgery with premium intraocular lens implants (IOLs). In order to help all of her patients achieve their best possible uncorrected vision, Dr. Nahl offers a range of advanced IOLs, including the multifocal ReStor and ReZoom implants. As a leading San Diego ReStor and ReZoom IOLs specialist, Dr. Nahl uses these lenses to help patients improve both their near and distance vision. To learn more about these sophisticated lens implants and to find out if you might be a San Diego ReZoom or ReStor candidate, please peruse the paragraphs below.

ReZoom

Unlike conventional single-vision (monofocal) lens implants, state-of-the-art ReZoom™ lenses have been specially designed with multifocal zones that provide good vision across the spectrum of varying distances and light conditions. So you can see well anywhere and anytime, be it near, far or in between. As a result, ReZoom San Diego patients no longer have to settle for monofocal lenses that only provide good distance vision with limited ability to see objects that are near without glasses.

The ReZoom™ Multifocal Lens is a clear, foldable implant made of a high-refractive-index acrylic material. This new technology multifocal lens is designed to provide a full range of vision - near, distance and intermediate - after cataract treatment.

Your Vision with A Rezoom™ Multifocal Lens

The ReZoom™ Multifocal Lens not only treats cataracts, but it may also turn back the clock to bring back much of your ability to see up close and at a distance.

The lens has multiple focal points so you can see well at a variety of distances in varying light conditions. If you have been diagnosed with cataracts with or without presbyopia and desire a full range of vision with increased independence from glasses or bifocals, the ReZoom™ Multifocal Lens may be the right solution for you.

Balanced View Optics™ Technology provides full-range vision

The ReZoom™ Multifocal Lens features Balanced View Optics™ Technology - uniquely proportioned visual zones that provide it with a major advantage. Each ReZoom™ Multifocal Lens is divided into 5 different zones with each zone designed for different light and focal distances.

Unlike other earlier multifocal lens designs, the ReZoom™ Multifocal Lens has proportioned the size of its zones to provide for good vision in a range of light conditions. For instance, some zones have been designed to offer greater low light/distance vision support during night driving.

How to know if the Rezoom Eye Surgery is right for you

If you are diagnosed with cataracts and are experiencing one or more of the following symptoms, you may be a candidate for the ReZoom™ Multifocal Lens:

  • Difficulty reading
  • Difficulty seeing close objects
  • Difficulty seeing to drive, especially at night
  • Changing glasses prescriptions
  • Needing bifocals

Ask the accomplished San Diego ReZoom IOLs specialist, Dr. Nahl, if the ReZoom™ Multifocal Lens is an option that is right for your lifestyle and eye health.

AcrySof® ReSTOR® IOL

Finally, the opportunity for freedom from reading glasses and bifocals.

Until recently, life without reading glasses or bifocals was not an option for most cataracts San Diego patients. They now have an option. The AcrySof® ReStor IOL is an artificial lens that is implanted in the eye to replace the eye's clouded crystalline lens during cataract surgery. It is a unique technological innovation that can provide San Diego ReStor patients with quality vision throughout the entire visual spectrum - near through distance – with increased independence from reading glasses or bifocals!

How does the AcrySof® ReSTOR® IOL work?

As we perform daily activities such as reading, watching television or working at the computer, our eyes are constantly focusing on objects at varying distances - up close, far away and everything in-between. The ability to quickly change focus throughout this range of vision is called accommodation Accommodation: The ability of the eye's lens to change shape to focus on objects at various distances. . Unfortunately, this ability diminishes as we grow older1, causing us to become dependent on bifocals or reading glasses. However, the AcrySof® ReSTOR® IOL was designed to provide quality near to distance vision by combining the strengths of apodized Apodization: The gradual reduction or blending of the diffractive step heights. The application of apodization to intraocular lenses is a patented process by Alcon and can only be found in the AcrySof® ReSTOR® IOL. diffractive Diffraction: The spreading of light. Occurs when light passes through discontinuities (i.e. steps or edges). In an optical system, light can be diffracted to form multiple focal points or images. and refractive technologies. Similar technology has been used for years in microscopes and telescopes to improve image quality, and has now been patented for use in intraocular lenses by Alcon.

Apodized Diffractive 

Apodization is the gradual tapering of the diffractive steps from the center to the outside edge of a lens to create a smooth transition of light between the distance, intermediate and near focal points. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. On the AcrySof® ReSTOR® IOL, the center of the lens surface consists of an apodized diffractive optic. This means that the series of tiny steps in that center area work together to focus light for near Near vision: Refers to focal points that are typically 16 inches or closer to your eyes. This is also known as "reading vision." Items that typically fall within the near range of vision are books, newspapers, and medicine bottles. through distance vision Distance vision: Refers to focal points that are typically 7 feet or further from your eyes. Items that typically fall within the distance range of vision are billboards, street signs, and movie screens.

Refractive

Refraction is redirection of light rays as they pass through the lens. It involves the redirection of light passing through the lens, to focus on the retina. The refractive region of the AcrySof® ReStor IOL bends light as it passes through the lens to a focal point on the retina. This outer ring of the AcrySof® ReStor IOL surrounds the apodized diffractive region and is dedicated to focusing light for distance vision. As a result of this sophisticated process, our San Diego ReStor IOLs patients experience great improvement in both their near and far vision.

Dr. Angela Nahl is proud of her reputation as a highly accomplished San Diego cataracts surgeon. In addition to performing cataract surgery with the multifocal ReStor and ReZoom IOLs, Dr. Nahl also offers Crystalens in San Diego. These lenses slightly move with the eye’s muscles, allowing the patient to change focus from near to distant objects. Dr. Nahl also specializes in laser eye surgery. For individuals who desire to eliminate their dependence on glasses through LASIK surgery but are not candidates for this procedure, Dr. Nahl offers implantable contact lenses (ICL). In fact, she is regarded as one of the best San Diego Visian ICLs specialists.
