Eye Care: Tower Clock Eye Center

Tower Clock Eye Center logo

Tower Clock Eye Center is an independent Ophthalmology practice providing medical and surgical eye care for patients in Northeast Wisconsin for more than 30 years.

The practice was started in 1980 by Karl Schwiesow, M.D. With the addition of Tyson Schwiesow, M.D. in 2002, Kurt Schwiesow, M.D. in 2005, and Matt Thompson, M.D. in 2010, Tower Clock Eye Center is proud to continue our tradition of excellence that has helped us become one of the most respected practices in the area.

The physicians provide comprehensive medical and surgical eye care, specializing in consultation and treatment for cataracts and glaucoma as well as corneal disease and refractive surgery.


Surgery should be considered when cataracts begin to interfere with your daily activities. It is not true that cataracts need to be “ripe” before they can be removed or that they need to be removed just because they are present. Cataract surgery can be performed when your visual needs require it.  If your vision interferes with your ability to perform daily tasks such as driving, reading, or watching television,  it may be appropriate for you and your eye doctor to discuss cataract surgery.

Tower Clock Eye Center is proud to be the first center in Northeast Wisconsin to offer FDA approved laser cataract surgery to our patients, and the first center in the entire state to use the Alcon LenSx laser cataract system.  The LenSx laser is one of the first lasers designed from the ground up specifically for cataract surgery.  Our staff are the most experienced laser cataract surgeons in the area, and will take time to discuss your laser cataract options with you prior to your surgery.


Glaucoma is the second leading cause of blindness worldwide, and is a disease of the optic nerve. Like a balloon, your eye needs a reasonable amount of pressure to maintain its shape, but too much pressure can damage the optic nerve and cause a loss of peripheral vision. Glaucoma is typically not painful and does not cause symptomatic loss of vision until it reaches an advanced state. Glaucoma is readily treatable, but screening and early diagnosis are very important.

<!– Three types of surgery, the NEW Trabectome procedure, Trabeculectomy and Tube Shunt surgery, are currently the gold standard.

Tower Clock Eye Center is proud to be the first practice in Wisconsin certified to perform the Trabectome procedure for the treatment of glaucoma. As one of the leading causes of blindness worldwide, glaucoma is a serious condition that is usually treated with eyedrops, laser, surgery, or a combination of all three. Dr. Kurt Schwiesow, our fellowship trained glaucoma specialist, treats glaucoma using the Trabectome procedure (removing a section of tissue to relieve high pressure in the eye), trabeculectomy (creating a “trap door” to drain fluid from the eye in a controlled manner), or tube shunt (inserting a device through which fluid can drain).



Dr. Thompson has performed thousands of procedures and has extensive experience with laser vision correction. His patients have included other ophthalmologists and professional athletes. He has completed a fellowship in cornea disease and refractive surgery. He uses the latest technology when performing LASIK.

ASTIGMATISM – When the cornea (the clear covering over your eye) is slightly irregular in shape, preventing light from focusing properly on the retina in the back of your eye. As a result your vision may be blurry at any or all distances. Most people have some degree of astigmatism. Eye exams help your doctor provide a proper prescription for eyeglasses or contact lenses. Depending on life and the degree of astigmatism, some patients prefer corneal modification (e.g., LASIK or other refractive surgery) to improve vision quality.

BLEPHARITIS – A chronic inflammation of the eyelids and eyelash follicles. It may be caused by seborrheic dermatitis, acne, bacterial infection, allergic reaction or poor eyelid hygiene. The eyes may become red or blurry, as well as tear frequently. The eyelids crust, flake, scale or redden, and the smooth inside lining of the lids may become rough. In more serious cases, infection can spread to the cornea. Treatment and preventive care involves thorough but gentle cleaning of the eyelids, face and scalp. Warm compresses can be applied to loosen crust, and dandruff shampoo can help keep the eyelids clear. This may be combined with antibiotics if a bacterial infection is causing or contributing to the problems.

DIABETIC RETINOPATHY – A complication of diabetes that weakens the blood vessels that supply nourishment to the retina (the light-sensitive lining in the back of the eye where vision is focused). When these weak vessels leak, swell or develop thin branches, vision loss occurs. Laser surgery is the treatment of choice.

DRY EYE – Eyes may become dry and irritated, resulting in redness, itching, and pain because the tear ducts don't produce enough tears or because the tears themselves have a chemical imbalance. Causes include aging, certain medications, and injuries. Dry eye is not only painful, it can damage the eye's tissues and impair vision. Fortunately, many treatment options are available.

MACULAR DEGENERATION – The macula is a part of the retina in the back of the eye that ensures that our central vision is clear and sharp. Age-related macular degeneration (AMD) the number-one cause of vision loss in the U.S. occurs when the arteries that nourish the retina harden. Deprived of nutrients, the retinal tissues begin to weaken and die, causing vision loss. Patients may experience anything from a blurry, gray or distorted area to a blind spot in the center of vision. Recent developments in ophthalmology allow doctors to treat many patients with early-stage AMD with the help of lasers and medication.

PRESBYOPIA – A natural change in our eyes' ability to focus. It occurs when the soft crystalline lens of the eye starts to harden, affecting the lens' ability to focus light in the eye, causing nearby objects to look blurry. Presbyopia happens to everyone starting in about our 40s or 50s — even in patients who have had laser vision correction. The effects an be corrected with glasses or contact lenses; multifocal lens implantation; conventional surgery; and monovision LASIK. (Laser surgeries such as conventional LASIK and PRK cannot correct presbyopia because they reshape the cornea rather than treat the lens.)

UVEITIS – an often chronic condition that involves inflammation of the middle layer of the eye, which contains the iris, ciliary body and choroid and is located between the retina and sclera (white of the eye). Most cases are treated through steroids in the form of eye drops, pills or injections to reduce inflammation in the eye.
