Cataract & Refractive Surgeon
Samuel Multack, DO, FAOCO is a board-certified Ophthalmologist and high-volume cataract surgeon whose career has been built around a more demanding standard: cataract surgery should not simply remove a cloudy lens—it should create a deliberate vision strategy for the life each patient wants to lead. He is also a Fellow of the American Osteopathic College of Ophthalmology (FAOCO).
Dr. Multack’s surgical experience informs individualized planning and clinical judgment. His practice is centered on refractive cataract surgery, femtosecond laser-assisted cataract surgery, advanced-technology intraocular lenses, astigmatism management and minimally invasive glaucoma surgery when clinically appropriate. Across the combined careers of MEC physicians throughout our history, the practice’s experience includes 100,000+ ophthalmic procedures spanning cataract surgery, laser treatments and other eye procedures.
Precision informed by outcomes
Dr. Multack believes experience is only valuable when it is measured. MEC tracks postoperative refractive outcomes against rigorous internal benchmarks and uses that feedback to continually refine diagnostics, lens selection and surgical planning. Every recommendation begins with the same question: which option offers this patient the best balance of clarity, range of vision and confidence?
As founder of Multack Eye Care and medical director of the Laser Cataract Institute, Dr. Multack helped build one of Chicagoland’s most advanced cataract programs—bringing sophisticated diagnostics, laser technology and a broad portfolio of modern lens options into a highly personalized surgical experience. His surgical experience helps inform the standards, systems and outcomes tracking used across MEC.
Training, teaching & leadership
Dr. Multack earned his undergraduate degree from Saint Xavier University and his medical degree from the Chicago College of Osteopathic Medicine. He completed his internship at St. James Hospital, where he was named Intern of the Year, and completed his ophthalmology residency as Chief Resident.
His academic work includes ophthalmology book chapters, peer-reviewed publications, clinical research and the education of medical students and residents. He has also been repeatedly recognized by physician-ranking and regional publications, including Castle Connolly and Chicago magazine.
A surgeon’s philosophy
Technology matters. Surgical volume matters. But judgment matters most. Dr. Multack’s approach is direct, data-informed and personal: understand the patient’s visual priorities, explain the tradeoffs honestly and execute the plan with exceptional precision.
