Dr Cronin is a Corneal & Anterior Segment Surgeon & the Director of Education at the Queensland Eye Institute in Brisbane Australia.
Dr Cronin grew up on the Gold Coast, Queensland and completed his medical and ophthalmic training in Brisbane. He trained in his subspecialty of Corneal, Refractive and Anterior Segment Surgery at the prestigious Manchester Royal Eye Hospital in the United Kingdom. this makes him one of the very few surgeons in Australia who have a. genuine fellowship in cataract and refractive surgery.
Dr Cronin has published articles in numerous international ophthalmology journals - some of his publications are listed below. He has written two textbooks “Ophthalmology for Medical Students” and “Ophthalmology for Medical Receptionists”.
Together with Dr David Gunn he developed the only online surgical planning tool for CAIRS surgery for Keratoconus - www.cairsplan.com . This tool is used by surgeons worldwide to learn how to perform this extraordinary cutting edge procedure for keratoconus.
When not at work he enjoys spending time with his wife & children.
What makes Dr Cronin different?
I have been the patient! I needed urgent eye surgery when I was a medical student. Thankfully the surgery went very well and I maintained excellent vision – thank you to modern ophthalmology!! That’s why I became an ophthalmologist. I fell in love with the amazing technology and treatments we have available. But this means I know what it is like to be in your position. I know what it is like to be nervous or even petrified at the thought of being awake for an eye operation.
So don’t worry. If you are having cataract surgery with me, you will be so heavily sedated you won’t remember any of the procedure. Just turn up to the hospital, meet the anaesthetist and wake up in recovery. The same applies to pterygium surgery, corneal transplants and the majority of other eye operations.
Dr Cronin is a member of numerous ophthalmic professional organisations including: RANZCO, he is a founding fellow of the World College of Refractive Surgery and Visual Sciences, and a member of the European Society of Cataract and Refractive Surgery, a member of the Refractive Surgery Alliance and the Australian Society of Ophthalmologists.
