About Your Cornea The Eye’s Natural Lens
The cornea is the transparent, dome-shaped structure that covers the front of the eye. A healthy cornea is clear and naturally curved in appearance. The rounded design of the cornea allows it to refract light into the retina so your eye can focus on both near and far away objects. If the cornea becomes swollen or misshapen due to injury or disease, light can be distorted or blocked. This can cause overall impairments to your sight.

Protect Your Eyesight With Regular Eye Exams
At Chu Vision Institute, we want our patients to maintain their best possible eyesight, so we advise everyone to have a comprehensive eye exam at least every other year. Routine vision exams are imperative to your total eye health, as we check for many conditions and impairments, including corneal irregularities. If corneal disease is detected during your eye exam, we offer numerous treatment options to limit further vision loss. Contact our team in Minneapolis, MN, today to schedule your exam so you can keep your ocular health in optimal condition.
Noticing Vision Changes? Trust Your Eyes to a Cornea Specialist
If you have observed changes in your vision, we recommend visiting our Bloomington, MN, office for a comprehensive eye exam. Conditions of the cornea can only be assessed and treated by a qualified professional, such as board-certified ophthalmologist Dr. Ralph Chu.
He is highly experienced in addressing many corneal conditions that can cause vision loss, such as keratoconus, Fuchs’ endothelial dystrophy, and bullous keratopathy. Our caring team understands that all corneal conditions are unique based on each patient, so we will work to find the best treatment for you.

How We Diagnose Corneal Disease
After you have arrived for your scheduled exam at Chu Vision Institute, one of our highly experienced optometrists will examine your eyes to search for signs of corneal disease, such as irregular eye shape, cloudy spots, and rough patches. We will also review your medical records, family history, and any current medications or previous surgeries. In addition, our team will perform a series of diagnostic tests to uncover any potential eye problems. At our state-of-the-art facility, we utilize some of the top technologies available in the industry.
What Causes Corneal Disease?
Corneal disease is primarily genetically inherited, but injury or excessive eye rubbing can also be contributing factors. People with corneal disease typically experience blurred or distorted vision, eye swelling, irritation, glare, and sensitivity to light.

Corneal Disease Treatments Tailored to You
At Chu Vision Institute, our team offers a range of both surgical and non-surgical treatments to address corneal conditions and protect your vision. For a damaged or unhealthy cornea, treatment options may include:
- Phototherapeutic keratectomy (PTK)
- Descemet’s stripping endothelial keratoplasty (DSEK)
- Full- or partial-thickness corneal transplant
At your initial consultation, Dr. Ralph Chu will determine which treatment best suits your condition and develop a customized plan to restore and preserve your eyesight.

I had cataract surgery for my left eye with the Light Adjustable Lens (LAL). Chu Vision Institute made sure my eyes were taken care of throughout the entire process. They were available at all times to answer questions and treat any issue if it should arise. Dr. Chu and his staff are well trained, trustworthy and walked me through every part of the process. I am pleased with my results and if my other eye should ever need cataract surgery, I would not hesitate to use them again. Thank you to Dr. Chu and his staff!
PRK was the best decision I have ever done. I wouldn’t have explored surgery options with any other clinic or surgeon. Eye surgery is nerve racking, but Dr Chu and his team had my FULL trust from day 1 and I knew I was in great hands. I am seeing the best I ever have and wish I would’ve done it sooner. If you’re reading this and need a sign to schedule an appointment, DO IT!
I had the most amazing experience at Chu Vision! Every aspect of my journey getting the Light Adjustable Lens' to correct my vision was wonderful. Can't say enough of Dr Chu and his team!
Dr. Chu is an excellent doctor. I felt confident in his knowledge and ability as a surgeon. He is a very kind and caring person and felt very comfortable with him. His staff is very efficient and friendly and my questions were addressed immediately. I would highly recommend Dr. Chu
I knew from the moment I walked into Chu Vision, this would be where I wanted to have my cataracts taken care of. The staffers are very professional, knowledgeable and helpful. There was never a time where I had questions, as Chu Vision was forthcoming with answers before being asked. I so appreciate all the help, and the gift of better sight.
I had been in need of cataract surgery for a while. I was having trouble finding a surgeon that I wanted to touch my eyes! Then my son had Laser Surgery at Chu Institute and was beyond thrilled. My husband and I were getting ready to relocate to Minnesota at that point, so I waited. Am I glad I did! It was close to a year later and I was no longer comfortable driving, so as soon as we got settled, I began the process. Everyone at the Institute was amazing! I had so many tests to make sure every possible spot of my eyes were examined. When I finally met Dr. Chu, I knew I made the right choice. He took the time to answer any questions I still had, patiently and clearly. The surgery day came and it was really quick. About 3 days later, not only was my eye getting clearer, but for the first time in almost 30 years I could see distance without my glasses!! I was absolutely blown away! A week later, I had the second eye done. I am 4 days in now and the first eye is just about perfect and the second is following close behind!! I can't sing the praises high or loud enough for Dr. Chu and his Institute! I highly recommend them and I promise you will not just be pleased, but THRILLED! Thanks to all the employees, Drs., Techs etc., for all your help and patience as I navigated this journey in my life!!
Even with my medical background, this was out of my area of expertise, so I was pretty nervous. Quickly I was reassured by their very comprehensive examination, excellent professionalism, efficiency and punctuality, excellent bedside manners and respect. Detailed information regarding the procedure was given and was always available upon request. My cataract surgery was 10 days ago, recovery was quick and the process of adjusting the lens focus will start in 3 weeks. Kudos to Dr. Chu and his team, keep it up.
Very thorough, professional, and uplifting
The teamwork at the Chu Vision Institute is fantastic. They are careful to answer one's questions, diligent about prepping for surgery, and of course the surgeons are top notch. Very pleased!
I had never had cataract surgery before, so thus was unexplored territory for me. The preparatory videos, however, were invaluable. I had numerous follow-up phone calls from Chu Vusion to make preparation even easier. I was totally at ease when I arrived. The procedure was quick and my recovery was totally painless.
I had LASIK done at Chu Vision today. I was so impressed with every step of the process. They have clearly thought of each step of the client experience. I am confident in the future health of my eyes and so glad I trusted Dr Chu and his team!
I have been going to Chu Vision for annual eye appointments for eight years. All annual appointments were done by caring professionals. This year, the need for cataract surgery came into the discussion and time was spent fully explaining the procedure. More information followed by videos and a meeting with Dr. Chu. The high level of personal care provided by everyone at Chu Vision was/is amazing! Both eye surgeries were recently done. I am on the mend and my vision is amazing! And, yes - I smile a lot! I highly recommend Chu Vision!
Chu Vision was recommended to me by a friend and I could not be happier with the facility and staff. Everyone was always so friendly, you can tell they all really enjoy what they do! Their scheduling was very quick and pricing is also comparable to others I have spoken to. Surgery day was a breeze and they made sure I was comfortable and understood everything that was happening and gave lots of encouragement. Dr Chu was great and super friendly! If I could give 10 stars I would!!
Light (adjustable) cataract surgery lens replacement. Satisfied with the results. Can see great at long distance and up close with glasses. Professionally run organization. Everyone was friendly and helpful. If I were to do it again, I would not go with the light (adjustable) lenses as it involves lots of trips to the clinic for tuning. I would go the next step down and hope for the best.
I had the EVO ICL procedure done and am so happy with the results!! It’s crazy to think I won’t need contacts or glasses anymore, and waking up each morning being able to see everything has been amazing. This procedure is absolutely life-changing, and I’m so glad I was in the care of Dr. Chu and his staff! They are the loveliest, kindest people I’ve ever met. I’m so grateful for them and the work they do for their patients!
This was by far the best eye vision clinic I have ever been to. They are so polite and caring. Dr. Chu absolutely knows what he is doing and so personable. Great job to the whole team. Thank you so much. Highly recommend Chu Vision Institute.
Absolute the Cadillac of any business I have been a part of. Excellent communication, empathic nurses and techs, excellent doctors, and best of all- my vision! I am blown away by the results of my cataract surgery. I was wearing (and looking for) readers all the time. I no longer need them! Incredible. Dr. Chu has built an excellent business with everything top of the line. Just an amazing experience!
If every health care facility operated as seamlessly and as patient oriented as this one, we would have truly compassionate, passionate and professional services that rival none other. I cannot overstate the extent to which I am satisfied with the service received. Every team member was professional, solicitous, and sincere in their interactions. I knew I was getting the best vision practitioners, what I didn’t know is that I was getting a whole new appreciation for first rate business practices. Congratulations and thank you for making me see the light (pun intended:) ).
I had a refractive lens exchange (RLE) procedure with Chu nearly 2 years ago, and I still think about how much it has improved my day-to-day life nearly every day! I had extreme myopia and astigmatism and was so dependent on contacts and glasses, neither of which were ideal. After my RLE, I don’t rely on any corrective eyewear. I’m 20/20, and it is so freeing! Yes, it is an investment, but I’m so glad I did it when I did (age 47). The team at Chu is the most professional, skilled and caring medical group I’ve ever experienced. They made sure all my questions were answered before and after the procedure, and they were so great with the older patients and their families! The procedure didn’t hurt, and the recovery time was quick. I would recommend Chu to anyone looking to improve their eyesight. Thank you, Dr. Chu and Team!
Chu Vision is a highly professional and extremely caring Institute. My cataract surgery went well and Dr. Chu and his entire staff were amazing! They truly cared for my individual needs and within a day my visual clarity returned to my eyes. I now have 20/20 vision without glasses. I will recommend this place to all my friends and acquaintances! Thank you Chu Institute!
I had the Implantable Contact Lens (ICL) procedure done at Chu Vision Institute, and I cannot say enough GREAT things about Dr. Chu and the ENTIRE staff at Chu Vision! I have been wearing glasses/contacts since I was in elementary school and now have 20/20 vision! They made the process so easy and were always available to answer my questions! At my initial consultation, I felt so educated about the different options that were provided to me and I never felt like I was being forced or pushed into something that wouldn't benefit me! I also felt like they listened to me and recommended the procedure that would fit into my lifestyle the most! I show horses all over the country and I cannot believe how much easier traveling and showing is without having to carry my contacts and glasses everywhere! It is so amazing waking up in the morning and being able to go right away without fumbling for my glasses! I will DEFINITELY be recommending anyone who is interested in vision correction to check out Chu Vision Institute!
I am so impressed with this clinic from start to finish. They are a well-oiled machine, and have clearly considered the patient experience all the way through. I felt comfortable and like I was in good hands for my LASIK surgery. I'm taking lessons for my own business in how thorough they are. Thank you, Dr Chu and his team!
Chu Vision did a great job. From the initial evaluations through the cataract surgery I had on both of my eyes. Everything went smoothly and as planned. It has now been three months. My vision is very good. I can now drive without glasses. I only need them to read that was my choice based on the surgery and the lens I chose.
I had cataract surgery. The care was unbelievable the team there made you feel comfortable and at ease. All my follow up visits was all about my healing process and even the phone follow up was comforting.
I walked into Chu Vision and my life has been forever changed. I had been wearing glasses for almost 25 years and after doing my research chose Dr. Chu for my surgery. I cannot comment enough about the wonderful staff. They were so kind, knowledgeable and were able to set my mind at ease. The surgery could not have gone any better. A steady hand from Dr. Chu and within seconds my first eye was complete. He softly and calmly talked me through everything he was doing and that was key. I have had 6 months without glasses and not a day has gone by that I haven't had an Omg this is awesome moment. If you are considering having this surgery call now and you won't be disappointed!
Dr Chu is an excellent kind efficient ophthalmologist. His staff mirrors his effective leadership. My experience with every staff person was excellent. They made me feel comfortable and confident that I was in good hands. My eyesight after the cataract removal and light adjustments is great near and far. Wow. So thankful to each and everyone at Chu Vision.
My mom recently had cataract surgery at Chu Vision, and the entire experience was absolutely wonderful. From start to finish, the team was timely, efficient, and incredibly caring. They made sure she was well taken care of before, during, and after surgery. The communication was exceptional—we always knew what was happening, our questions were answered clearly, and the whole process was explained with care. Dr. Chu and his team went above and beyond, and the follow-up was outstanding. We couldn’t be more grateful for the excellent service and experience!
Chu Vision deserves 5 stars! Starting from initial visit to last eye exam after cataract surgeries one week apart on both eyes. Top notch surgeon and employees! Best decision I made and given the best gift of clearer colorful vision! Wearing cheaters now to read.
Chu Vision Institute is a very efficiently and professionally run clinic. My cataract surgery was so successful! It seems like my vision is continuing to improve - it is clearer and colors are so vibrant. I'm so greatful to Dr. Chu and his terrific team!
Chu Vision is amazing! Everyone who works there is phenomenal. With my Light Adjustable Lens I made many trips to this wonderful facility. I was always treated with kindness and compassion by everyone who works there. Dr. Chu is so knowledgeable, amazing and very professional. He really cares and is so compassionate with all his patients as was Dr. Banal in the clinic also. I would highly recommend Chu Vision to anyone who needs cataract surgery. I wish I could give them higher than a 5-star rating!
Got LASIK done in both eyes yesterday and I couldn’t be happier. I’d recommend Chu Vision to anyone interested in LASIK surgery. Dr. Chu & everyone there did an amazing job throughout the whole process. They made me feel less anxious, and very comfortable throughout the procedure.
The procedure itself was painless and a lot less scary than it seems. Within 24 hours of the surgery, I’m seeing clear and my eyes feel normal. LASIK is truly life changing and better than I could have ever imagined. Chu Vision is the best in the business!
Totally positive experience with Dr. Chu and his office. There aren’t words that adequately express the patience, kindness and friendship received from Dr. Chu and every one of his staff involved with my care. Receptionists, office staff, doctors, technicians, nurses (!) - all were so professional and so happy to be helpful in answering questions, providing support and making the experience so positive. Very highly recommend Dr. Chu and his entire office for any service they provide.
My experience at ChuVision was seamless, thorough and informative. My vision results are spot on to all that was expected. At times I felt the number of appointments was somewhat over the top but in reflection it’s about my eye sight which is very important to me. My rating is 5 stars. Thank you ChuVision.
Dr. Chu and his team are truly world-class. I had the ICL procedure done on both eyes, and the entire experience was outstanding.

Thank you, Dr. Chu and staff — you’ve earned a lifelong patient!
I had lasik done with Dr. Chu in April 1998. Best thing that I ever did for myself !! Now that I needed cataract surgery this fall, I would never go to anyone else.

He is so sincerely incredible with such a kind and caring heart…Thank you Dr. Chu!!!! Has been a great experience with all of the staff too!!!

Preserve Your Vision With Corneal Cross-Linking in the Twin Cities
If you’ve been diagnosed with keratoconus or progressive corneal thinning, corneal cross-linking (CXL) is a clinically proven way to stabilize your vision and prevent further damage. At Chu Vision Institute in Bloomington, we offer this FDA-approved treatment to patients from Minneapolis, St. Paul, and across the Twin Cities.
CXL involves applying riboflavin (vitamin B2) eye drops and activating them with controlled UV light. This strengthens the cornea by creating new bonds between collagen fibers. The procedure is quick—usually under an hour—and requires minimal downtime.
Is Cross-Linking Right for You?
CXL may be recommended for patients with:
- Early to moderate keratoconus
- Post-LASIK ectasia
- Other corneal weakening conditions
Dr. Chu and our experienced team use advanced diagnostics to evaluate your corneal health and determine if CXL is the right path forward. Most patients return to daily activities within a few days and experience long-term visual stability, and in some cases, clearer vision.

Take the First Step Toward Better Vision Schedule a Corneal Exam at Chu Vision Institute

If you have noticed changes in your eyesight, contact us in Bloomington, MN, to schedule a consultation. We look forward to helping patients in the Twin Cities, Minneapolis, and St. Paul areas get on the path to better eye health.


Cornea Treatment All Your Questions Answered
What are corneal diseases?
Corneal diseases are a variety of illnesses that damage the cornea, the transparent outer layer of the eye. After an injury or illness, the cornea can frequently heal by itself, but more severe conditions—infections, degenerative illnesses, and deterioration—will need to be treated.
Can bacteria cause a corneal infection?
As a result of bacteria or fungus getting within the cornea, keratitis, an inflammation of the cornea, can occasionally develop along with an infection. These germs can enter the eye through a deep wound and cause corneal ulcers, inflammation, and infection. This kind of infection can also develop as a result of a contact lens-related injury, albeit it is rare.
What is ocular herpes?
Ocular herpes is a viral eye infection that can recur. The herpes simplex virus I (HSV I) is the primary cause of ocular herpes. Ocular herpes causes ulcers on the cornea’s surface that may scar and impair eyesight. The cornea and eye can become more deeply inflamed. Ocular herpes has no known treatment; however, antiviral medications can frequently control it.
Can shingles affect the eye?
In patients who have already experienced chickenpox, the herpes zoster virus can resurface, causing shingles. The chickenpox virus typically remains dormant in the body’s nerves after the onset. Later, it may move down these nerves and infect certain organs, such as the eye. Blisters or lesions on the eye, fever, and discomfort from damaged nerve fibers are all possible symptoms of herpes zoster. Corneal lesions often heal on their own, but antiviral medication may accelerate the process.
What causes corneal disease?
Corneal diseases can be caused by a number of things. Some diseases develop because of bacterial, fungal, or viral infections. In other cases, age may be the cause. Cataract and intraocular lens implant surgery can also cause patients to develop bullous keratopathy in rare instances. Other factors that lead to the development of corneal diseases include heredity, contact lenses, eye trauma, certain eye diseases, and systemic diseases.
Can corneal damage be repaired?
Many corneal problems can be effectively addressed with corrective lenses, over-the-counter eye drops, or prescription medications. Some patients require additional therapies, such as phototherapeutic keratectomy (PTK). With cutting-edge laser technology, PTK reshapes the cornea, removes scar tissue, and restores eyesight clarity. This may be required if corneal dystrophy has advanced to the point of considerable vision loss or if a corneal injury or infection has left behind permanent scarring that seriously compromises vision. A cornea transplant is another possibility for treatment if your cornea can’t be repaired with other options.
What are the signs of corneal disease?
The cornea typically heals following the majority of injuries or diseases due to its capacity for fast restoration. However, if the cornea is severely damaged, the healing process may take longer, which could lead to a number of symptoms, such as:
- Pain
- Distorted vision
- Tearing
- Redness
- Extreme light sensitivity
- Scarring on the cornea
How common is corneal disease?
There are several common types of corneal diseases. Corneal transplants are the most common type of transplant surgery. While some types of corneal diseases are rare, others, such as Fuchs’ dystrophy, keratoconus, map-dot-fingerprint dystrophy, and lattice dystrophy, are the most common.
Can you go blind if your cornea is damaged?
Your vision and eye health are greatly affected by your corneas. Because of this, severe corneal injury and advanced corneal disease can cause vision loss and even blindness. However, there are medications, individualized laser treatments, and corneal transplants available. New stem cell treatments are also being researched. These treatments can help stop vision loss before it worsens or prevent it from becoming a major issue.
Can laser surgery fix corneal scarring?
Many people who develop corneal scarring for any reason may be informed that there is no cure. However, more recent laser procedures known as “phototherapeutic keratectomy” (PTK) can smooth out the cornea’s distorted structure while also removing opacities. The advanced LASIK procedures use the same excimer laser technology as this one. Based on the location and degree of the damage produced by the scarring, advanced diagnostic imaging will assist in creating the specific therapy profile for each scar. PTK is designed with the goal of reducing your need for glasses or contact lenses. For individuals who have developed corneal scarring due to problems with their contacts, this is fantastic news. In order to completely eliminate the requirement for contact lenses, the other healthy eye will typically be treated concurrently with LASIK.
