As an ophthalmologist, I am frequently consulted by other doctors about the need for surgical correction of various eye diseases. In advising patients, I draw upon my more than 30 years of clinical experience, fellowship training in corneal surgery and a conservative medical philosophy. After listening to patients and performing a thorough examination, I typically offer a step-ladder approach, outlining therapeutic options, thereby allowing my patients to participate in their care.


Dr. Steven Koenig graduated from Dartmouth College summa cum laude and was elected to Phi Beta Kappa. He graduated from Cornell University Medical College and completed his ophthalmology residency at Northwestern University. Following residency, he was accepted for a prestigious two-year fellowship at LSU Eye Center under the guidance of Dr. Herbert Kaufman. Dr. Koenig joined the faculty of the Eye Institute in 1983 and was promoted to full professor in 1988. His practice includes cataract, corneal and refractive surgery (LASIK) with a strong emphasis on laser vision correction, one-stitch corneal transplantation (DSAEK and DMEK) and no-stitch cataract surgery. (learn more on his website)


He is certified by the American Board of Ophthalmology, has received the Honor Award from the American Academy of Ophthalmology and was elected to the Cornea Society, a distinguished professional society of corneal surgeons. Dr. Koenig has served as a scientific referee for all the major ophthalmology journals and has served as an examiner for the American Board of Ophthalmology. He has been at the forefront of new corneal transplantation techniques such as DSAEK and DMEK and has written extensively in this area, with more than 100 articles published in the scientific literature.  Dr. Koenig has participated in the training of a number of ophthalmologists and corneal surgeons and has been repeatedly selected by his peers as one of the “Best Doctors in America” and “Best Doctors in Milwaukee.”

Dec. 20, 2019
This was followup from surgery at the Surgery Center which I found difficult in obtaining scheduling of surgery and lack of communication
Dec. 10, 2019
He is just a phenomenal Dr. easy to talm to and he cares about his patients.....

Nov. 12, 2019
He always took the time to discuss any concerns I had in terms I fully understood
Nov. 11, 2019
Doctor appeared to be too professional by not providing human connection. Apparent workload schedule may contribute to the lack of personal interaction.
Nov. 11, 2019
Dr. Koenig always treats me with kindness and respect and tries his best to address my eye issues. I like to be informed and have an understanding of the conditions I am being treated for. Providing Printed information on ones eye problem or upcoming procedure would give patients a better understanding of what to expect.
Oct. 28, 2019
Dr. Koenig has excellent credentials, an excellent reputation, and was "as advertised" in person. I was very pleased with this appointment.
Oct. 25, 2019
I have trust in Dr Koenig and all the staff
Oct. 18, 2019
He is a caring, highly skilled and empathic man.
Oct. 18, 2019
I really like, trust and respect this provider and I know he is extremely knowledgeable and smart. I also feel he really loves his work/job. However, he has a "little" tendency to give the illusion of being in a hurry at times. I am a bit sensitive in this area so when it happens (not always) it is a bit disconcerting to me.
Oct. 18, 2019
Dr. Keonig and his staff were excellent. Thanks for the outstanding review of my issue, and advice on how to proceed.
Oct. 4, 2019
Excellent doctor.sYou could make this survey better if yo put more questions per page and move the page changing arrows to the center of the form. You are sending to people who have bad eye sight and why you increase the print to a size you can read at the arrows disappear and you have to keep downsizing the print very annoying.
Oct. 4, 2019
Very knowledgable
Sept. 27, 2019

Very thorough and personable. outstanding individual.
Sept. 2, 2019
In the early stages of seeing Dr. Koenig. Hope he and your staff will figure this all out. We've had an excruciating 12 months previously.
Aug. 31, 2019
over all the best experience I have had at a doctor's visit..even despite not hearing back yet to schedule my surgery despite calling to see about scheduling.
Aug. 30, 2019
dr. Koenig could have cared less about me as a person and my questions about my eye health. he was abrupt, dismissive and patronizing. I won't be returning to this office nor could I in good faith recommend this practice to others. dr. Koenig could use significant training in compassion empathy and listening skills. technical expertise does not a doctor make...
Aug. 28, 2019
Although the computers and Epic were down the day I was there, everyone was still very thorough and positive.
Aug. 27, 2019
Answered my questions always, seemed to care about my situation.
Aug. 27, 2019
Doctor Koenig is the only Doctor i would trust to do any eye surgery. He is respectful and very knowledgeable in his field.
Aug. 24, 2019
I made the appointment because my optometrist thought I had an eye disease. Dr. Koenig was able to put my concerns at rest by letting me know I do not have that disease. I told him I had been experiencing variability in my sight for 5 or more years, and I didn't feel as though he grasped that this was an underlying concern that still mattered to me. Even so, that underlying concern had not been great enough for me to pursue it over the years - so all-in-all I got my needs met.
Aug. 13, 2019
Appreciated the fact that Dr. Koenig was able to see us so quickly following a referral from another corneal opthalmologist from Racine.
Aug. 2, 2019
Dr. Koenig is great. My issue with coming to Froedtert was the incredibly poor directions and zero help from the individuals directing traffic on finding the road to the surface lot to park. You need to fire who is in charge of this. If 2 kind doctors who saw me pulled over hadn't tried to help, I would have driven away. I get that this guys directing traffic are minimum wage employees with limited capacity or caring to go out of their way to help, but the person in charge of them is fire the company you use so that patients can navigate the construction without duress.
Aug. 1, 2019
Dr. Koenig is very knowledgeable, & professional & has treated me very respectfully during my office visits and eye surgeries. He is genuinely concerned about my eye issues & makes me feel confident I am in good hands..
July 26, 2019
Excellent coordination of services to assist me with my appointment. I was confident I received the best medical service.
July 11, 2019
Dr. Koenig is outstanding.
July 11, 2019
long wait time. dr ran very behind
July 2, 2019
I waited 55 minutes to be seen even with an appt.
June 27, 2019
I have every confidence in Dr. Koenig's treatment and advice. However, we are at a special time in my eye care and felt a little lost coming out of the appointment with regard to the 4 choices given. I feel that I needed a little more guidance. Not sure I knew what questions to ask besides the "obvious".
June 25, 2019
somsewhat arrogant and in a hurry to get on with patients who needed him in his opinion more
June 20, 2019
Dr. Koenig and his staff provided excellent care. Most complete and throughly explained eye exam I ever had. I now totally understand my condition, next steps and needed followup. Froedtert and Medical College of Wisconsin doctors are amazing.
June 17, 2019
no,Excellent Doctor and staff.Parking valet was a excellent idea.
June 16, 2019
very efficient, no duplication of efforts from the team, which had me out quickly. straight answers about questions
May 14, 2019
"I believe I was treated correctly and with kindness."
May 12, 2019
I have no issues with the provider. I did not give a 10/10 for this OFFICE due to the administrative end. Out of the 4 times I saw Dr.K, I was rescheduled (without say) twice, and asked to reschedule another time. That is 3 out of 4 times! I understand things happen, but the last time, it was just so the staff could leave early on the weekend. But you must understand, your patient's also work and have other obligations. The other issue was with billing. Though I made 2 payments, as instructed by Lasik staff, and have the credit card statement to show this, I still got a bill from Froedert stating only 1 payment made! When I called the help #, they stated someone will look into it, it will take 4-6 weeks! So, to recap, Provider and MA's=awesome, auxiliary staff involved = not impressed. Thank you for your time.
May 5, 2019
Dr. Koenig was outstanding in how well he explained my eye disease and my upcoming surgeries. He gave me a great deal of confidence that he is very knowledgable and is the doctor I want to perform my surgeries. My husband and I were very impressed with Dr. Koenig.
May 3, 2019
After seeing provider and his recommendation of surgery the wait time was to long.
May 2, 2019
I am very please and grateful for the care I have received from Dr. Koenig. Thank you Dr. Koenig!
April 30, 2019
Dr.Koenig and his staff are all very knowledgeable & professional.
April 29, 2019
Completed a full review of both eyes using terms that not explained. It would have been helpful to understand what was being done and why. It seemed a bit intimidating to ask for a play by play after the fact. Provider was respectful and made sure I understand the overall recommendations for the future. The Tech did not introduce herself at the start of the appt. When the provider left the room it wasn't clear what I should do next or if I should be waiting for the tech to return with the written summary of the visit or where I should have received that. No follow up on how I felt to drive or if I needed dark shades as my eyes were dilated during the visit. Felt a bit unsafe with the final exit.
April 29, 2019
he listened and seemed as he truly cared about my eye and the outcome of my upcoming surgery. Very happy with my experience

April 19, 2019
Wait time to see provider is usually excessive. If this Dr. was not as good as he is, I would switch to another Dr. because of wait time to see Dr.
April 18, 2019
I greatly appreciated Dr. Koenig's confidence, knowledge, and straight forward approach. As a patient I needed to know my provider is experienced and confident. That allowed me to trust his judgement and know I was in good hands. He made time for me in his busy schedule.
April 12, 2019
This doctor is very easy to deal with, explains exactly what you need to do for him to give you the care you need. Procedure went perfect.

They took very good care of me! Thank you!!
March 30, 2019
I appreciated getting my concerns addressed in one swift, effective visit with a courteous, well functioning team, and a highly professional physician.
March 27, 2019
now that I have been diagnosed with kateraconous, it would be nice to get in and fix it. 6 month wait! I understand you need to wait in line but 6 months of dealing with this disease and knowing it and then not being able to get in and get a procedure done in less than 30-60 days is ridiculous. I know it's not life threatening but it vision that's needed for your job and your family. someone needs to look into this and turn Tuesday and Thursday availablity of procedures into 3 days a week minimum maybe 4 during peak times
March 25, 2019
very helpful with my questions
March 22, 2019
long wait in waiting room and exam room. provider seemed distant
March 20, 2019
Dr K has always been very thorough and extremely professional in trying to advise me about my eye issues and extremely skilled in resolving them.
March 16, 2019
he seemed irritated when I asked questions about my condition and seemed like he wanted to just get out of there as fast as possible
March 13, 2019
Doctor Koenig and staff were very informative and professional.I was impressed
March 12, 2019
Nothing could have been better. It was a perfect experience.
March 6, 2019
Just a couple of medical terms/conditions that he was dictating to his nurse that I wasn't aware of or had never heard that I would have liked Dr Koenig to take a little more time explaining to me.
March 5, 2019
Doctor Koenig had done surgery on my left eye 4 years ago and I have great results. I trust him to do the surgery that is needed for my right eye. He is very through and I have confidence in him.
Feb. 27, 2019
Excellent visit, very friendly staff, a very professional visit with excellent advice.
