Miss Lydia Chang

Consultant Ophthalmic Surgeon


Specialises in

I am a Consultant Ophthalmic Surgeon with subspecialty expertise in glaucoma. I trained at the world-renowned Moorfields Eye Hospital in London and attained consultant status in 2008. My research doctorate (based at the Institute of Ophthalmology in London) was in the field 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 drives my dedication to providing a highly personal approach to looking after my patients.

Current Leadership Positions: Ophthalmology Clinical Lead North West Anglia Trust Foundation Trust, Getting It Right First Time (Clinically Led Quality and Efficiency Programme): Ophthalmology Clinical Advisor since 2016 onwards. A project to assess reducing unwarranted variation in clinical practice in ophthalmology and improving clinical outcomes in England.

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.
