Cataract Surgery – Vision Correction Options
There are several options available to you to achieve both distance and near vision after cataract surgery.
There are many options available to you as a patient to achieve your desired visual goal after cataract surgery. This is probably the most important decision you will need to make about your cataract surgery. Please take the time to review your options and ask questions of your surgeon during your visit to our New Eyes office. It is important for you to understand ahead of time that no guarantee can be made as to how well a patient will see after cataract surgery, that not every option is available or appropriate for every patient, and that results may differ from what was predicted or planned.
Dr. Pizio and staff were wonderful. I can see again!

Monofocal intraocular lenses (IOLs) have one point of focus – a single focus. Your surgeon can use a monofocal IOL to target far or near vision, but the monofocal IOL does not do both distance and near vision at the same time. For example, you can choose to have monofocal IOL lenses implanted in both eyes for distance vision and wear separate reading glasses, or you can have monofocal IOL lenses implanted for near vision and wear separate glasses for your distance vision.
Cataract Surgery: Monofocal IOL
Monovision involves implanting a monofocal IOL in one eye that aims for distance vision and an IOL in the other eye that aims for near reading vision. Monovision is a common way of correcting presbyopia, but it is not suitable for everyone. Some patients can adjust very well to monovision. However, the majority of patients cannot adapt to this imbalance and vision may seem blurry both near and far. Depth perception decreases as a result of eyes not working together for all tasks. The people who adapt best to this method are those who have already tried and liked monovision with contact lenses or LASIK.
Accommodating Monofocal IOL
Accommodating IOLs are lenses that have a single focal point which is primarily set for distance in most patients and can provide some limited intermediate vision. The focal point can slightly move position in the eye so that the objects at distance are clear when the eye focuses on them, but when the eye looks at a near object, the IOL will shift its focal point to bring the nearer object into focus. Accommodating IOLs achieve this by physically moving inside the eye in response to the focusing action of the muscles inside the eye. The only FDA approved IOL of this type is called the Crystalens®. Patients implanted with the Crystalens® IOL generally enjoy distance and some intermediate vision without glasses. These lenses don’t work well on patients with weak eye muscles. The eye muscles become weaker with age.
The newest technological advances in IOLs focus on lenses that allow patients the freedom and lifestyle to see distance, intermediate, and near without wearing glasses. The ReSTOR® and TECNIS® Multifocal are the latest styles of multifocal lenses that are designed to replace cataracts and correct presbyopia at the same time. These IOLs do not depend on the eye muscles moving the lens for the near vision. A multifocal IOL can provide in both eyes the same distance vision as a monofocal IOL and excellent near vision without wearing glasses or contacts. There is no imbalance between eyes such as in the monovision correction. Multifocals are distance-dominant lenses and do require brighter light for the sharpest near vision. All intraocular lenses including monofocal IOLs can have shadow, reflective, glare, or halo visual qualities, especially at nighttime. Multifocal IOLs have more prominent circle effects around bright lights at night, which diminish over time.
TECNIS® Symfony IOL
The TECNIS® Symfony IOL is a revolutionary type of intraocular lens that offers numerous benefits for patients who need cataract surgery and have a desire for freedom from wearing glasses. This FDA-approved IOL is able to help patients focus through an extended range of focus on objects at far distance, intermediate, and near without the need for glasses or contact lenses. It can be particularly advantageous if you suffer from presbyopia, a condition that is common among people over 40 years of age and causes blurriness when looking at objects at a close range. In a clinical study, patients who were given the TECNIS® Symfony IOL achieved a higher level of vision improvement at near and intermediate distances, while attaining a similar improvement of far-distance vision, when compared with those who were given a TECNIS® monofocal lens. The Symfony group of patients was also found to be much less likely to need any corrective eyewear following the procedure.
The TECNIS® Symfony IOL has been studied in numerous clinical trials and has proven to provide many people with high-quality vision in a comprehensive range of lighting conditions. It has also been shown to reduce the likelihood of halos and glare around lights, and give patients continuous clear vision without visual “drop-offs” between far, intermediate, and near distances.
Another version of this intraocular lens – the TECNIS® Symfony Toric IOL – can help patients who have presbyopia and astigmatism. The Toric IOL can significantly reduce the blurry and distorted vision associated with astigmatism, giving patients a chance to see clearly without the need for glasses or contact lenses. Our New Eyes cataract surgeon will perform a thorough evaluation during the initial consultation and talk with you about the many customized IOL options we offer.
Your New Eyes surgeon, Dr. Helga Pizio, Dr. Ksenia Stafeeva, or Dr. Roman Fajardo, will explain the advantages of each type of IOL that may be ideal for your unique needs, and will answer all of your questions. Together, you and your New Eyes surgeon can determine the option most likely to bring you the best possible vision after cataract surgery.
