Dr. Michael S. Korenfeld, MD, ACOS is a Board Certified ophthalmologist. He was recently inducted into ACOS, the American College of Ophthalmic Surgery. This organization only inducts ophthalmologists who contribute significantly to the advancement of ophthalmology and eye care. Dr. Korenfeld is a Founding Member of ACOS, and was inducted by a vote of other ACOS members because of his 20 years of performing FDA-approved clinical trials and his ophthalmic surgical inventions, which are used in operating rooms around the world.


Dr. Korenfeld initially went to Tulane University (New Orleans) for his undergraduate work, and then obtained a Bachelor of Science in Biology from the University of Arizona (Tucson) with a minor in Music Composition. He then attended Medical School at Washington University at St. Louis. Because of his interest in research and ophthalmology, Dr. Korenfeld obtained a National Eye Institute grant and performed glaucoma research under the mentorship of the chairman of the department at Washington University, Bernard Becker, MD. After this, he performed a Transitional Internship at St. Johns Mercy Hospital (St. Louis) and then completed an Ophthalmology Residency at the Mason Eye Institute (Columbia, MO), where he continued his research endeavors and won First Prize in a national research competition for research performed on the corneal endothelium. Washington University then contacted him to be their Chief Resident for a year. This prestigious honor was only once bestowed on a doctor who did not attend their residency program. Currently, he is actively engaged in the teaching ophthalmology to training eye surgeons at Washington University, and he was just recognized for his 20th year of service.


Dr. Korenfeld has been doing research since 8th grade, when he received his first grant from the University of Missouri-St. Louis to study the behavior of fruit flies, based upon the color of their eyes. A subsequent grant was obtained from Washington University to study Bone and Mineral Metabolism while he was in high school. Because he achieved the highest ranking in Immunology while matriculating at the Washington University School of Medicine, Dr. Korenfeld was awarded another grant to study new HLA antigen types under the auspices of the Howard Hughes Medical Institute. Since his residency in ophthalmology, all of his research has shifted from “bench top” research to clinical trial research. He has been the Principal Investigator for over 70 FDA-approved clinical trials for both pharmaceuticals and ophthalmic devices, and has been involved the development of most of the eye drops that you can currently purchase at the pharmacy. Dr. Korenfeld is actively engaged in clinical trial work, and is currently performing studies in glaucoma, cataract surgery (intraocular lens implants and drugs used with cataract surgery), dry eye, blepharitis, inflammation, infection, and allergic eye diseases. He has also started to perform clinical trials for esthetic conditions, like the use of Latisse for sparse eyelashes and eyebrows.

If you have one of these conditions, please contact our office to see if there is a clinical trial that matches your needs. Alternatively, you can go to the Clinical Trial section of our web site, and contact us that way.

Our State-Of-The-Art Practice

Because Dr. Korenfeld is so involved in clinical trial research, and because the sponsors of this research demand that the investigators have the best and most up-to-date equipment, our office can offer you state-of-the-art eye care every day. We have a large and beautiful facility, which contains over 70 pieces of original art work, including paintings, photography, sculpture, and hand blown glass pieces. The Comprehensive Eye Care facility is actually an alternative art gallery that is registered with the St. Louis Gallery Association. Since the work we do is dedicated to the improvement of vision, Dr. Korenfeld insisted that the facility be very visually stimulating and appealing to the eye.

We welcome the opportunity to care for you and trust you will find our office different from any medical office you have ever visited.

Dr. Nathan Tuttle OD is the optometrist here at Comprehensive Eye Care, Ltd. He has been working here since 2011 and he specializes in vision correction, especially contact lenses.

He also treats and monitors many eye health conditions including glaucoma, dry eyes, macular degeneration, and cataracts. He is also actively involved in the before and after surgery visits for Dr. Korenfeld’s patients. 

Dr. Tuttle is from southwest Missouri and received his Bachelors of Science degree in cell and molecular biology from Missouri State University in 2005. He then attended Southern College of Optometry in Memphis Tennessee where he graduated with his Doctor of Optometry degree in 2009. During his last year of school his first external rotation was in pediatrics at Vision Enhancement Clinic in Springfield Missouri. His next rotation was in ocular disease and surgery management at Missouri Eye Institute, also in Springfield MO.

Dr. Tuttle has been married since 2004 and has two beautiful children. He enjoys playing soccer and running. He has been on multiple missions to Mexico and speaks fluent Spanish.
