Information About Vision Services

At Chu Vision Institute, our team performs a comprehensive range of treatments for a large number of eye-related disorders and diseases. Some of the conditions we offer solutions for include glaucoma, cataracts, keratoconus and other cornea-related issues, and refractive errors (such as myopia, hyperopia, and presbyopia). Our Bloomington, MN team is most renowned for our work with laser vision correction, such as LASIK, SMILE, refractive lens exchange, and PRK.

LASIK is a widely performed laser eye surgery that has gained worldwide recognition for the stunning results it produces for millions of adults.

PRK (photorefractive keratectomy) was the first revolutionary laser eye surgery to address and reverse refractive errors, like myopia and hyperopia.

Small incision lenticule extraction (SMILE) is an innovative refractive laser surgery done to address nearsightedness (myopia) in our patients.

Implantable contact lenses are a popular option for patients who want to gain clearer eyesight without undergoing laser vision correction surgery.

Cataracts occur when the proteins of the eye lens begin to degrade or cluster, resulting in impaired vision that can eventually lead to blindness.

We offer several types of artificial intraocular lenses (IOLs) to help cataract surgery patients see more clearly with less reliance on eyeglasses.

Refractive cataract surgery utilizes femtosecond laser technology to precisely remove cataracts before placing custom IOLs to provide clearer vision.

During traditional cataract surgery, an extremely fine incision is created in the eye to remove the cloudy lens and replace it with an artificial IOL.

Refractive lens exchange is an incredibly diverse technique that can be performed to address a wide range of issues and correct many eye conditions.

Glaucoma is a serious disease that causes damage to the optic nerve and can lead to vision loss, but symptoms can be managed under professional care.

Minimally invasive glaucoma surgery (MIGS) encompasses several advanced procedures that help lower intraocular pressure in patients with glaucoma.

The iStent is a tiny device placed into the eye's trabecular meshwork to help lower intraocular pressure by creating a new fluid drainage channel.

The Hydrus Microstent is a tiny implant device designed to reduce eye pressure in glaucoma patients by allowing for increased fluid drainage.


Selective laser trabeculoplasty (SLT) is a minimally invasive glaucoma treatment that utilizes focused laser energy to lower intraocular pressure.


Endoscopic cyclophotocoagulation (ECP) is a minimally invasive procedure that delivers a targeted laser beam into the eye to lower fluid production.

The cornea is the translucent, round window on the front of the eye, which acts as a protection mechanism and refracts light to provide clear vision.

The KAMRA corneal inlay is surgically implanted into a tiny opening in the eye to correct presbyopia and reduce dependence on bifocals or readers.

Dr. Chu performs both full- and partial-thickness corneal transplants to remove diseased or damaged tissue and replace it with a healthy donor sample.

Descemet's stripping endothelial keratoplasty (DSEK) is a partial-thickness corneal transplant used to remove and replace damaged corneal layers.


Phototherapeutic keratectomy (PTK) uses state-of-the-art lasers to treat scarred corneal tissue or other irregularities to help improve eye health.

Also known as nearsightedness, myopia is a common refractive error that makes it difficult for people of all ages to see objects from far away.

Hyperopia, also called farsightedness, is a common refractive error that makes it difficult to see items up close, including words on a page.

Presbyopia is characterized as vision loss in patients 40 years of age or older and develops when the inner lens of the eye loses flexibility.

Dry eye syndrome can lead to blurry, bloodshot eyes, as well as significant discomfort. When not treated, pain may persist in the long-term.
