Contact lens fittings, vision therapy, and primary eye care in Allied Gardens, San Diego, define the practice of Michael C. Berner, OD, at Kaiser Permanente's Zion Medical Center on Zion Avenue. He practices within the Southern California Permanente Medical Group at 4647 Zion Avenue, where the integrated care model connects optometry directly to ophthalmology, endocrinology, and neurology departments housed at Kaiser Permanente Zion Medical Center. That on-campus referral pipeline means patients flagged during routine exams for elevated intraocular pressure or suspicious optic nerve cupping advance to glaucoma subspecialists without leaving the facility. Dr. Berner's vision therapy work addresses convergence insufficiency, accommodative disorders, and eye-tracking deficits that affect reading performance in both pediatric and adult patients. The 92120 campus occupies a site south of the 8 freeway along the Zion Avenue corridor, within walking distance of the Allied Gardens commercial district on Waring Road. Contact lens designs span rigid gas-permeable, soft toric, and multifocal options, with trial lens inventories kept on site for same-visit dispensing. Post-dilation and glaucoma medication prescriptions fill at pharmacies including Alvarado Compounding & Retail Pharmacy, which compounds specialty ophthalmic formulations for patients who require preservative-free preparations. He also maintains a secondary practice location at the Vandever Medical Offices on Vandever Avenue in the 92120 ZIP.
