About Cataract Lenses
Cataracts are a leading cause of vision loss across the globe. Luckily, with cataract surgery, Dr. Ralph Chu at Chu Vision Institute can correct this loss. When it has been determined that it is time to remove the cataract, you have many options for correcting your vision. Modern cataract surgery allows Dr. Chu to use modern surgical techniques and technologies, providing the most precision and accuracy to your visual outcome. Laser-Assisted Cataract Surgery is one of these tools. Dr. Chu was the first in Minnesota to offer Laser-Assisted Cataract Surgery with the VICTUS Femtosecond Laser.
During refractive cataract surgery, your eye lens is removed and replaced with an artificial intraocular lens (IOL). Sometimes referred to as an implant, an IOL is an artificial lens placed in the eye to function just like your eye's natural lens. Thanks to cutting-edge developments in ocular technology, advanced IOLs can now correct or improve any existing refractive errors, such as nearsightedness, farsightedness, or astigmatism. As a result, you may become less dependent on glasses or contacts. Board-certified ophthalmologist Dr. Ralph Chu is pleased to offer several advanced IOL options for patients who undergo refractive surgery to remove cataracts. Prior to your surgery, Dr. Chu will provide you with options for standard and advanced IOLs to meet your unique vision needs and lifestyle. If you are experiencing cloudy eyesight associated with cataracts, contact Chu Vision Institute in Bloomington, MN. Our expert team looks forward to sharing more about advanced techniques and technologies to help you obtain clearer vision.
What Are my Cataract Lens Options?
At Chu Vision Institute in Bloomington, MN, we offer a number of different IOLs for patients who have refractive cataract surgery. Dr. Chu will help you choose an IOL based on your current eye health, lifestyle, and vision needs. We offer the following lenses:
Types of Lenses
- Monofocal IOLs – This type of IOL can correct vision at one focal point (at close up, intermediate, or far away distances). Patients who select monofocal lenses typically still require the use of reading glasses.
- Toric IOLs – Toric IOLs provide clearer vision following refractive cataract surgery for patients with astigmatism. These IOLs work similarly to toric contact lenses. Just like monofocal IOLs, toric IOLs correct vision at one distance.
- Multifocal IOLs – These advanced IOLs are designed to simultaneously provide correction for both near and far away vision. Patients who receive multifocal IOLs are able to reduce or eliminate the need for glasses or contacts following surgery.
- Accommodating IOLs – These IOLs help reduce dependence on reading glasses by "flexing" within your eye to help you more easily focus your vision. Accommodating IOLs work well to improve vision at mid-range distances.
- Extended Depth of Focus (EDOF) IOLs – These lenses are designed to expand your depth of focus to provide crisp, sharp vision at near, far, and intermediate distances. Many patients who have EDOF lenses have drastically reduced or minimized their dependence on eyeglasses.
Lifestyle Lens Options
- Crystalens and Trulign IOL – The Crystalens® and Trulign® accommodating intraocular lenses (IOL) are designed to correct a wider range of vision following cataract surgery.
- AcrySof IQ PanOptix Trifocal IOL – The AcrySof® IQ PanOptix® trifocal intraocular lens (IOL) is designed to help patients see in multiple ranges of vision from close to distance following cataract surgery.
- Tecnis Symfony IOL – The Tecnis® Symfony Extended Range intraocular lens (IOL) is the first and only Extended Depth of Focus presbyopia-correcting IOL that provides continuous, high-quality vision at any distance following cataract removal surgery.
- AcrySof ReSTOR IOL – The AcrySof® ReSTOR® multifocal intraocular lens (IOL) is designed to help patients see in multiple ranges of vision from close to distance following cataract surgery.
"Bare with my lengthy review but if you’re like me, I wanted to know what others true thoughts were and I scoured as many reviews as possible to make sure I was making the best decision for me and my eyes. I am SO, SO thankful for Dr. Chu and Dr. Heckman’s expertise and honesty. I decided it was time to get Lasik and went in for my consultation. From check-in to my latest follow up, everyone at the Chu Vision Institute was friendly, warm, and helpful. Due to some past corneal scarring, Dr. Chu recommended that I get Lasik on one eye and PRK (ASA) on the other. I was extremely nervous about PRK because of the slightly longer recovery time and I really just wanted to wake up and have 20/20 vision like my friends who have had Lasik. The day of my procedure, they made sure I had all my questions and concerns answered before they let me in to have my surgery. That was extremely comforting to me and Dr. Heckman explained why PRK was recommended over Lasik. Simply put, I wouldn’t have had a good outcome if Dr. Chu had performed Lasik on both eyes. Both procedures went well and Dr. Chu confirmed his right decision during the procedure which took all of maybe 10 minutes for both eyes. As instructed, I went home and rested and could literally see 20/20 the next day with my Lasik eye. The PRK eye takes a little longer to heal but can already see better! (I was worried my blurry eye would affect my vision, but it did not). Recovery has been great and will continue to get better in the next few weeks. Now my husband wants to get his eyes done. Chu Vision Institute has exceeded my expectations and I am very happy with my results!"- E.M. / Google / Oct 20, 2020
"I had cataracts removed from both eyes. Dr. Chu and his staff were wonderful to work with. From the exam to the surgical procedure and recovery, everyone was very professional and pleasant . I had a perfect outcome and would highly recommend the Chu vision Clinic."- B.S. / Google / Oct 02, 2020
"I’ve been going to Chu vision for about three years now and and I’ve had excellent service each and every time. They follow me yearly for my dry eye condition. They are extremely thorough and take the time to answer all my questions. Highly recommend them."- C.S. / Google / Jul 31, 2020
"Exceptional. I felt like family as soon as I walked through the front door. Staff was extremely knowledgeable and friendly and my LASIK procedure went flawlessly. Like most folks, I did extensive research for months before my consult (word of mouth and online) I highly recommend Chu Vision for your procedure."- C.M. / Google / Mar 19, 2020
"I want to thank everyone at Chu Vision for the remarkable care we received recently. The clinic has an immaculate protocol to prevent Covid exposure for all of its patients. One might think that all the masks would prevent a warm, caring environment but not at Chu Vision! To a person, everyone was warm and welcoming. Dr. Chu was terrific and extremely thorough. The clinic was able to assess my husband’s acute vision change using a remarkable variety of tests and tools. What would have taken weeks at another clinic took only hours at Chu Vision. We won’t ever go anywhere else. Thank you so very much!"- K.D. / Yelp / Jul 13, 2020
Choosing your lenses
Before your cataract removal procedure, our skilled optometrist, Dr. Heckman, will conduct a comprehensive eye exam to diagnose your cataracts and determine your specific refractive error (nearsightedness, farsightedness, or astigmatism), if any. This will help determine which IOL would work best to meet your vision needs. During your consultation, Dr. Heckman will review all IOL options available based on your vision goals (like whether you want the ability to read or drive without glasses). Your daily lifestyle, vision needs, and individual preferences will all factor into which IOL is chosen. Along with Dr. Heckman, Dr. Chu will also provide you with the necessary information to help you choose the best intraocular lens to improve your vision.
What to Expect with Your New IOL
Your cataract surgery will be performed at our ambulatory surgery center, conveniently located adjacent to Chu Vision Institute. Prior to the procedure, our team will review what to expect in terms of results, when you might anticipate vision improvements, and any recovery instructions. Since refractive cataract surgery with an artificial IOL is a personalized procedure, outcomes can vary with each person. The majority of patients at Chu Vision Institute are pleased with their results with many reporting some of the best vision they have had in years. With an IOL, you do not have to worry about getting cataracts again in the future since your new artificial lens is designed to stay in place and not break apart. However, a possible future complication known as PCO (posterior capsule opacification) could cause blurred, cloudy vision. Fortunately, this condition can be easily treated.

The team at Chu Vision Institute in Bloomington, MN is committed to helping patients see better after cataract surgery by providing some of the most technologically advanced IOL options available. An artificial intraocular lens (IOL) can not only replace a natural lens damaged by cataracts, but it can correct refractive errors.
