Pepose Vision Institute is a multi-specialty ophthalmology and optometry practice serving the Greater St. Louis area from offices in Chesterfield and South St. Louis County. Its current services emphasize laser vision correction, cataract and lens-based surgery, corneal disease, dry eye, glaucoma, comprehensive eye care, and retinal disease services.
Practice history: Pepose Vision has served St. Louis and the surrounding Midwest since 1999.
Founder: Jay S. Pepose, MD, PhD, founded the institute and served as its Medical Director before retiring from clinical practice in August 2024.
Current established provider roster: Mujtaba Qazi, MD; Ibrahim Sayed-Ahmed, MD, MS; James Rieger, OD; Karrissa Siegel, OD; and Amanda Parisi, OD, formerly Amanda Edmiston.
Cornea and Refractive Surgery Fellow: Eli Pratte, MD, has a current Pepose Vision physician biography identifying him as a Cornea & Refractive Surgery Fellow receiving advanced subspecialty training at the institute.
Current ophthalmic surgeons: Dr. Qazi and Dr. Sayed-Ahmed are the established surgeons shown on the main current doctor directory; Dr. Pratte is separately identified as a physician fellow rather than an established attending surgeon.
Research infrastructure: Pepose Vision, with support from the Midwest Vision Research Foundation, maintains an active ophthalmic clinical-research program led by Principal Investigator Mujtaba Qazi, MD.
Historical LASIK role: The practice states that it was the first practice to offer LASIK in the St. Louis region and participated in early excimer-laser clinical research.
Practice Philosophy
Personalized care: Pepose Vision describes treatment planning as individualized to each patient’s ocular findings, lifestyle, visual priorities, and long-term goals.
Physician continuity: The current homepage states that the same physician guides surgical patients from consultation through surgery and follow-up rather than relying on repeated handoffs.
Technology-supported decision-making: advanced diagnostics and multiple treatment options are used to tailor care rather than apply one procedure to every patient.
Patient education: the practice emphasizes explaining examination findings, treatment choices, and expected care steps before proceeding.
Long-term eye care: services extend beyond elective vision correction to chronic conditions such as glaucoma, corneal disease, dry eye, diabetic eye disease, and retinal disorders.
Urgent-care access: patients with sudden visual changes or urgent postoperative issues are instructed to telephone the office, with an answering service facilitating physician callbacks after hours.
