Professional profile

I have been a consultant ophthalmic surgeon for nine years with subspecialty expertise in glaucoma. I trained at the world renowned Moorfields Eye Hospital and the Western Eye Hospital in London. My research doctorate (based at the Institute of Ophthalmology and the Royal Free Hospital in London) was in the field of glaucoma surgery, investigating the mechanisms contributing to scarring after glaucoma surgery. I completed my advanced glaucoma fellowship training at Moorfields Eye Hospital. My training has embedded in me an evidence based, patient focused approach to the way I look after my patients. I perform cataract and glaucoma surgery and have a special interest in the more recent glaucoma interventions; namely minimally invasive glaucoma surgery (MIGS) including the iStent, the Xen stent as well as glaucoma laser therapies such as laser iridotomy and selective laser trabeculoplasty.

I am an expert in assessing glaucoma patients, interpretating glaucoma data ranging from straightfoward cases to the more complex, higher risk cases. The ageing population in the UK is increasing and we all deserve to be sighted until the end of our lives. Although glaucoma is usually a disease of older age, it can start to develop in your 40's without symptoms, resulting in irreversible visual loss for some. I use the most technologically advanced glaucoma diagnostics tests to investigate my patients. I am committed to delivering a highly personal approach to looking after my patients, since I believe this is vital for ensuring I can deliver the best possible clinical outcomes.

I regularly perform cataract surgery and trabeculectomies. My (posterior capsule rupture complication rate for cataract surgery is well below the national average (as measured by the Cataract National Data Set, published in Eye 2011). From 2010, I introduced microinvasive glaucoma surgery to suitable patients and often perform this surgery.

Getting it Right First Time (Clinically Led Quality and Efficiency Programme): I have just been appointed to the ophthalmology team as Clinical Advisor. This is a project to look at reducing variation in surgical practice in ophthalmology and improving clinical outcomes. Community Ophthalmology and Primary Eye Care Frameworks (2015-16): I was the Royal College of Ophthalmologists' representative in the working group developing the frameworks (guidelines) for community ophthalmology and primary eye care. I was proud to be able to work with committed professionals, the objective being to develop integrated pathways to deliver effective eye care services in the community. The Community Ophthalmology Framework was published in July 2015 and is available on the Royal College of Ophthalmologists' website.

Lydia Chang is registered with all of the major private health insurance companies including: BUPA AXA-PPP PruHealth Vitality Allianz Aviva WPA She can also offer a self funding package.
