What Are Intraocular Lenses (IOLs)?

Intraocular lenses are the standard, permanent lenses placed in the eye following cataract removal or Clear Lens Exchange. Much like the lens of a camera, IOLs are what focuses your vision and delivers a clear, sharp image.

What Is The Difference Between Standard & Premium IOLs?

Premium, or Advanced Technology, IOLs are a type of intraocular lens used not only to replace the eyes lens following cataract removal but also to correct astigmatisms and near- and farsightedness, specifically. While standard IOLs improve vision, reading glasses or contact lenses will be needed down the line. With premium IOLs, patients greatly reduce dependency on reading glasses or contact lenses and experience a lifetime of clear vision.

Are Premium IOLs Right For Me?

If you answer “Yes” to any of these questions, you may be a candidate for intraocular lenses.
  • Are you nearsighted, farsighted, or have an astigmatism?
  • Do you want to greatly reduce dependency on reading glasses or contact lenses?

Frequently Asked Questions

Are there multiple types of intraocular lenses?
Yes! There are types of IOLs available for patients seeking this treatment option. Each IOL type corrects vision in a unique manner, targeting certain pre-existing eye conditions and vision capabilities. Katzen Eye group offers the following:
  • Monofocal IOL: Assists patients in distance activities and helps lessen the dependent on glasses.
  • Advanced Technology IOLs (AT IOLs): Offers variable distance viewing with greater possibility that glasses or contacts will not be needed.
  • Extended Range of Vision IOL: Provides less dependence at all distances and offer greater freedom from eyewear than traditional monofocal IOLs.
  • Toric (or Astigmatic) IOLs: Reduces or eliminates corneal astigmatism while greatly improving distance vision in patients.
  • Accommodating (Crystalens) IOL: Corrects vision by changing focus as the patient views objects at varying distances.
How long does the initial consultation take?
About 2 hours, including the diagnostic procedures.
Can both of my eyes be treated with IOLs during one procedure?
Ophthalmologists will only treat one eye at a time. An average time between surgeries is usually two weeks, but that may depend upon the individual patient and doctor.
How long does surgery take?
Typically, cataract surgery will take approximately 10 minutes. You should experience no pain before, during, or after your surgery.
