Nuvision Centers - Ironwood

Dr. Allison Wooten founded the practice in 2017 with the acquisition of Ironwood I Care, followed by the expansion into Excel Vision in 2020. A 2017 graduate, she was recognized by her peers and mentors with the graduating class clinical award for contact lenses.

Dr. Wooten specializes in medical eye care, with a deep focus on Dry Eye Center of Excellence protocols and scleral lens fitting. She is known for her hands-on approach to complex cases, often guiding patients through vision recovery and disability claims following complications from ill-fitting lenses elsewhere. Dr. Wooten is the only provider in the group who sees pediatric patients as young as two years old.

Patients choose Dr. Wooten for her exceptionally thorough exams, engaging communication, and personalized approach to eye care. She is frequently described as knowledgeable, energetic, and attentive, someone who listens closely and takes time to explain what she’s seeing and why it matters. 

Dr. Wooten is known for walking patients through test results and options in detail, tailoring recommendations to lifestyle, visual demands, and budget. Patients appreciate that appointments run efficiently and on time, while still feeling unrushed and highly individualized. 

Her combination of clinical precision, modern diagnostic technology, and patient education makes her especially popular with patients who want to fully understand their eye health and feel actively involved in decision-making. 

Clinical Expertise 

Comprehensive eye exams, vision optimization, technology-driven diagnostics, patient education, lifestyle-based glasses, and lens guidance.

Dr. Nha Cao completed a residency in cornea and contact lenses. Like Dr. Wooten, she was a recipient of the clinical award from her graduating class for contact lenses, underscoring her expertise in specialty fits.

She serves as a primary provider for scleral lens patients. While she is primarily based at the Ironwood location, she also provides specialty care at the Excel office to ensure patients have access to advanced corneal solutions.

Patients choose Dr. Cao for her calm, reassuring presence, deep clinical expertise, and genuine commitment to both patients and team care. 

She is widely trusted for her thoughtful, thorough approach, especially when patients feel anxious or unsure about their eye health. Dr. Cao takes time to listen, explains findings clearly, and helps patients feel confident in their care plan, all while keeping visits efficient and running on time. 

Clinically, Dr. Cao has advanced expertise in specialty contact lenses, orthokeratology, and anterior segment care, making her a go-to doctor for patients with complex vision needs or specialty lens requirements. Patients value her ability to combine technical skill with compassion and clarity. 

Beyond the exam room, Dr. Cao is known for being supportive and hands-on—whether that means helping answer phones, assisting a patient in optical, or stepping in wherever help is needed. That team-first mindset translates into a smoother, more caring experience for everyone who walks through the door.
