What is the difference between Ophthalmology and Optometry?
Ophthalmology is the medical specialty focused on the diagnosis and the medical and surgical treatment of eye diseases and vision problems. Ophthalmologists perform laser and scalpel surgery to treat conditions such as cataracts, glaucoma and retinal diseases. An ophthalmologist is a Medical Doctor (MD) or a Doctor of Osteopathic Medicine (DO).
Optometry is the specialty performed by a doctor of optometry (OD) that focuses on maintaining and enhancing vision and overall eye health. Optometrists perform vision exams and prescribe glasses/contact lenses to correct refractive errors.They are also trained to diagnose and medically manage some eye diseases.
Dr. Zelenak and Dr. Bulow work collaboratively to provide comprehensive, coordinated eye care for every patient.

Dr. Daryl Zelenak is a board-certified ophthalmologist who has been helping patients in Mid-Michigan see more clearly since 2003. He specializes in treating cataracts, glaucoma, diabetic eye disease and macular degeneration. He offers treatments including advanced technology lens implants, minimally invasive glaucoma surgery, and intravitreal injections. He also offers laser treatments for glaucoma, retinal diseases, floaters and secondary cataracts.
For cataracts, he offers advanced technology lens implants that can reduce and possibly eliminate the need for glasses. For glaucoma, he provides several minimally invasive surgical options — including the iStent™ (a tiny implant that helps lower eye pressure), goniotomy, ECP endoscopic laser treatments, and other advanced laser therapies such as SLT, DSLT and MLT.
