Miss Lydia Chang

Consultant Ophthalmic Surgeon


Specialises in

I am a Consultant Ophthalmic Surgeon with sub-specialty expertise in glaucoma. I trained at Moorfields Eye Hospital in London and attained consultant status in 2008. My research doctorate (at the Institute of Ophthalmology in London) was in the subject of glaucoma surgery. I completed my advanced glaucoma fellowship training at Moorfields Eye Hospital. My research training has embedded in me an evidence-based, patient-focused approach when caring for my patients.

I regularly perform cataract surgery and glaucoma operations. I have a special interest in the more recent glaucoma interventions; namely minimally invasive glaucoma surgery (MIGS) including iStent® implantation as well as glaucoma laser therapies such as laser iridotomy and selective laser trabeculoplasty. My posterior capsule rupture complication rate for cataract surgery is well within the national average range (as measured by the National Ophthalmology Database Audit Report 2016).

I am an expert in assessing glaucoma patients, interpreting glaucoma data ranging from straightforward cases to the more complex, higher risk cases. I use the most technologically advanced glaucoma diagnostics tests to investigate my patients. My commitment to delivering the best possible clinical outcomes accompanies my dedication to providing a highly personal approach to looking after my patients.

I am registered with all of the major private health insurance companies including: BUPA, AXA-PPP, PruHealth, Vitality, Allianz, Aviva, and WPA. I can also offer a self-funding package.

I am available most days and evenings except Wednesday and Thursday. Please contact my secretary below for appointments.

I am a wife and mother to two children. I relax by exercising – training with a personal trainer as well as attending an outdoor boot camp on the weekends. I particularly look forward to our family skiing holidays and walking in the Lake District. I love my holidays with my family and we have travelled quite extensively across the world. I love my food and I enjoy trying out new recipes. I enjoy reading, especially historical novels.
