Dr. Phoebe Sinn is an optometrist in Allied Gardens who practices at Kaiser Permanente's Zion Medical Center, 4647 Zion Ave, San Diego 92120. Dr. Sinn graduated from the Southern College of Optometry in 2009 and holds California optometry license #13795, with a clinical practice spanning comprehensive eye exams, contact lens management, and ocular disease evaluation. Her diagnostic caseload at the Zion campus includes astigmatism correction, presbyopia management for progressive lens candidates, pterygium monitoring, and treatment of both farsightedness and nearsightedness across pediatric through geriatric age groups. Walk-in urgent eye concerns including acute conjunctivitis, corneal abrasion, and foreign body removal that arise outside Kaiser's scheduling availability can be initially assessed at Perlman Clinic Mission Gorge in Grantville before follow-up with Dr. Sinn's office. The Kaiser integrated record system at this Allied Gardens facility allows Dr. Sinn to flag systemic medication side effects that affect vision, cross-referencing prescription lists from primary care and psychiatry departments within the same Zion campus. Dr. Sinn also maintains a practice location in Carlsbad, but her Zion Ave schedule serves the 92120 ZIP covering Allied Gardens, Del Cerro, and Grantville. Glaucoma screening through tonometry and visual field mapping is a recurring component of her exams, particularly for patients over 40 and those with a family history of intraocular pressure elevation. Geriatric patients in the Allied Gardens area whose vision loss intersects with residential care needs can coordinate through La Mesa Elder Care in San Carlos, where vision-related fall prevention is part of the intake assessment. YAG laser capsulotomy for posterior capsule opacification after cataract surgery is among the post-surgical co-management procedures Dr. Sinn monitors at this San Diego Kaiser location.
