Dr Chang is the director of Eastwood Eye Specialists. He is an experienced consultant ophthalmologist who provides holistic, patient-centered eye specialist care with an emphasis on unparalleled attention to detail and clinical precision.

Dr Chang always strives for the highest standard of medical and surgical treatment. He takes great care in listening to his patients and taking that extra time for communication so that they obtain a tailored understanding of their diagnosis and treatment options.

Dr John Chang specialises in complex cataract surgery in eyes with macular degeneration, diabetic retinopathy, glaucoma or uveitis. Such patients require highly individualised treatment plans that may include intraocular anti-VEGF injection therapy, intravitreal slow-release steroid implant, micro-invasive glaucoma surgery, or retinal laser.

Dr Chang takes pride in being meticulous at every step of the surgical journey of his patients, including comprehensive pre-operative clinical eye assessment using the latest technology, choice of intraocular lens implant, and of course the dexterity and confident surgical precision for the eye surgery itself. Dr John Chang also consults at Strathfield Eye Surgery.

As well as providing supervision to training eye doctors, Dr Chang is able to provide his patients in need, appropriate access to such charity funded cataract surgery.
