Cataract Lens Options


Choosing the correct Lens for Cataract Surgery


 Standard Lens
 Toric Lens Multi-Focal Lens


There are multiple choices available for cataract surgery and each has its own advantages and disadvantages.  All lenses used by Dr Yuen and Dr Tokunaga are FDA approved and come highly recommended by both Doctors and patients.

Standard Lens

Standard Lens help correct distance vision and most common among patients who undergo cataract surgery.  This lens will require the patient to wear glasses for reading after cataract surgery and does not correct for astigmatism.  This lens is covered by your insurance with you just being responsible for your co-pay.

Toric Lens

  • Astigmatism means the cornea is abnormally shaped making it difficult to focus light causing vision to be blurred. 
  • Toric Lenses help correct distance vision as well as astigmatism in the cornea.  
  • The toric lens helps correct the abnormality giving you the best vision possible.  

Tecnis Symfony Extended Depth of Focus (EDOF) Intraocular Lens

The Tecnis Symfony lenses were approved by the U.S. Food and Drug Administration on July 15, 2016. The approval was based on results of a U.S. pivotal study involving 298 patients.  In clinical studies the Symfony lens:

  • Provided seamless, day-to-night vision. Patients could see objects sharply and clearly at near, intermediate and far away distances, and points in between.
  • Provided high-quality vision. Some IOLs may leave patients with an inability to focus clearly due to competing wavelengths of light passing through the lens at different angles (known as chromatic aberration), or with vision that is not completely focused because of the shape of the lens (known as spherical aberration). The Symfony lens has been engineered to correct these issues.
  • Demonstrated a low incidence of halo and glare, which may be perceived as rings or blurring around bright lights. Glare and halo can sometimes affect an individual’s ability to drive at night or to perform other visual tasks.
