Services
Comprehensive Eye Exam
Our comprehensive eye exams evaluate visual acuity, eye health, and systemic health indicators. Using advanced diagnostics like Optos imaging, we detect conditions like glaucoma and macular degeneration while ensuring accurate prescriptions. Patients receive detailed explanations of their eye health and personalized treatment plans. This service is essential for maintaining optimal vision across all ages.
Myopia Management
Specialized myopia control programs slow childhood nearsightedness progression using FDA-approved MiSight lenses and orthokeratology. Our evidence-based approach reduces long-term risks of severe eye disease while improving daily visual function. Regular monitoring ensures treatment effectiveness and patient safety through childhood development stages.
Specialty Contact Lenses
We fit complex contact lens solutions including scleral lenses for keratoconus, hybrid lenses for irregular corneas, and multifocal designs for presbyopia. Our optometrists use precise corneal mapping to create customized lens parameters that maximize comfort and visual clarity for patients with challenging prescriptions.
Dry Eye Treatment
Advanced dry eye therapies combine LipiFlow thermal pulsation, intense pulsed light therapy, and autologous serum drops to address underlying causes. Our diagnostic workup identifies meibomian gland dysfunction and tear film instability, enabling targeted interventions that restore ocular surface health and reduce chronic discomfort.
Pediatric Eye Care
Early childhood eye exams detect developmental issues like amblyopia and strabismus. Our pediatric specialists use age-appropriate testing methods to assess visual acuity, focusing ability, and binocular coordination. We implement vision therapy programs to correct functional vision problems that impact learning and development.

I always get great care from Dr Lam & associates. It was a pleasure meeting Dr Walsh today. She asked great questions and showed that she truly cared about my eye health. She reviewed my past results and walked me through the comparison with the current exam.
