Premium IOL


Premium Lens Options

There are several premium lens options that are designed to help decrease your dependency on eyeglasses or contact lenses to see well after cataract surgery. Some lenses are more suited for maximizing patients’ distance vision, while other lenses provide excellent distance vision as well as good intermediate (computer) and near (reading) vision. Premium IOLs such as Extended Depth of Focus (EDOF), Multifocal, and Toric lenses give patients the ability to reduce or eliminate the need for glasses or contacts after cataract surgery.

Toric IOLs and Astigmatism Correction

Most patients have some corneal astigmatism, which is when the cornea is more oblong in shape like a football rather than perfectly round like a soccer ball. Even if you don’t have astigmatism correction in your eyeglasses or contact lenses, you may have significant astigmatism in your cornea that might be neutralized by your natural lens. If this corneal astigmatism is not corrected at the time of cataract surgery, it can affect sharpness of vision at all distances. For patients that have corneal astigmatism, vision is often sharper after cataract surgery when this astigmatism is surgically corrected. This can be done with manual or laser corneal incisions (for mild astigmatism) or with toric IOLs (astigmatism-correcting IOLs). Toric IOLs can be single-vision (for distance only) or combined with EDOF technology to enhance intermediate and near vision in addition to distance vision.

EDOF and Multifocal Lens Implants

EDOF and multifocal IOLs give patients undergoing cataract surgery the best chance of reducing or eliminating their need for reading glasses or bifocals. EDOF lenses provide an excellent range of vision from distance to intermediate to near reading vision. Multifocal lenses come in different powers and are specifically designed to provide excellent distance and near vision, often times with some intermediate vision also. Some of these lenses are available in toric powers that correct for astigmatism as well. Patients may still need reading glasses for fine print, such as the small print on the back of a medicine bottle. Patients may also need readers for poorly lit areas, such as dark restaurants, and highly skilled near vision tasks such as needle-point. With multifocal lenses in particular, there is a slightly higher chance of seeing haloes and/or glare with the lens implant.

Tecnis Premium Intraocular Lens Options

Toric IOL

  • Excellent distance vision

Corrects moderate to large amounts of astigmatism only, for enhanced sharpness at distance

Symfony EDOF IOL

  • Excellent distance vision
  • Superb intermediate vision
  • In many cases, good functional reading vision at about 20-21 inches (52 cm) and perhaps even closer.
  • It comes in a Toric version to correct for astigmatism as well

EDOF = extended depth of focus. This is the best choice for “all-around vision”. It has a low incidence of glare and very low incidence of haloes, less than traditional multifocal IOLs, almost comparable to basic monofocal IOLs.

ZKB00 Multifocal IOL +2.75 Low Add

  • Excellent distance vision
  • Good near-vision at about 19.5 inches (50 cm) approximate reading distance
  • Good intermediate vision

Designed to achieve a balance between reading and intermediate-vision activities such as lap reading, computer vision, reading the car dashboard, and grocery shopping. It has a low incidence of haloes and glare, less than other multifocal IOLs.

ZLB00 Multifocal IOL +3.25 Low Add

  • Excellent distance vision
  • Superb near-vision at about 16.5 inches (42 cm) approximate reading distance

Designed for most patients’ average reading distance, favoring activities such as newspaper and book reading, and use of a smartphone or tablet.
It has a low incidence of haloes and glare.

ZMB00 Multifocal IOL +4.00 Near Add

  • Excellent distance vision, often with haloes
  • Excellent near-vision at about 13 inches (33 cm) approximate reading distance

Best for patients favoring near-vision activities such as up-close reading (including small print) and knitting.
It has a higher incidence of haloes and glare than other multifocal IOLs.
