Monofocal Intraocular lenses

Standard Monofocal Lenses

are used in the majority of cataract procedures. These lenses have the advantage of excellent quality distance vision under a variety of lighting conditions. Since these lenses have a fixed focal point which is generally set for distance vision, reading glasses are typically required for good near vision. For patients willing to use reading glasses for near tasks, these lenses are an excellent choice.

Several million such lenses have been used for decades with excellent outcomes and safety record. Recent refinements in the optical quality of these lenses have allowed an even higher quality of vision than previously achievable. Monofocal IOLs allow patients to see at distance, but not at near.:

  • Allows for excellent distance vision

  • Does not correct for near (reading) and may not correct for intermediate (computer) vision

  • You will most likely need glasses for reading and computer


In certain individuals, the brain can tolerate a difference of one-two degrees between both eyes:

  • Standard lenses are used in both eyes

  • The non-dominant eye is made to be near-sighted so reading and potentially computer vision (or vice versa) can be accomplished without glasses

  • One eye is clear for distance and the other eye is blurry for distance

  • Does not have significant side effects of glare and halo

  • May require an adjustment period as the brain learns how to use the two eyes with separate functions
