Mr Daniel Calladine was appointed as consultant ophthalmic surgeon in the Worcestershire Acute Hospitals Trust in 2013. He trained in Oxford and London, where he gained advanced sub-specialty skills in cataract, cornea, transplantation and external eye disease. A senior clinical and research fellowship in Nottingham followed this, again concentrating on diseases of the anterior segment, ocular surface and complex transplantation.
He has a keen interest in the techniques and equipment used in micro-incision cataract surgery and complex cases. In particular the commercially available “Calladine capsulorhexis forceps” have helped to improve the quality and safety of micro-incision cataract surgery.
His research into cataract surgery incision imaging has been recognised throughout the world. He was one of the first surgeons to look at techniques for improving cornea micro-wound architecture using optical coherence tomography. This work led to improvements in blade design and the understanding of how to create better and safer incisions. He has published extensively on the subject of cataract surgery as well as writing book chapters on the subject. He was also the first author of a major Cochrane review update comparing multifocal intraocular lenses with monofocal lenses for cataract surgery. These type of lenses aim to correct both distance and reading vision to help patients be less dependent on glasses.
He carefully and prospectively audits his work. His outcomes are compared to the best international benchmarks. His current cataract and clear lens exchange surgery complication rate for posterior capsule break since starting as a consultant in 2013 is 0.00% (n=700). This is in spite of a case mix of very complex surgical cases.
He is a member of the United Kingdom and Ireland Society of Cataract and Refractive Surgeons and the European Society of Cataract and Refractive Surgeons. He is a Fellow of the Royal College of Ophthalmologists and a member of the Oxford Ophthalmological Congress.
Mr Calladine runs the cornea graft service and over the past 3 years has performed over 100 endothelial cornea grafts (DSEKs), one third of these have either been combined with cataract surgery or deemed complex cases. Despite this he has over a 99% surgical success rate and a 100% record at graft utilisation using a manual hand dissection Melles' technique. Internationally, he runs surgical wet labs teaching new microsurgery techniques to produce ‘ultra-thin’ cornea DSEK transplants.
He is a keen exponent of the latest techniques for stabilising the cornea in keratoconus, using collagen cross-linking with a UV laser setting at 10mWcm2. This produces approximately a 50% depth ‘cross-linking’, which augments the strength of the superficial cornea while not damaging the endothelial cells on the inside of the cornea.
His latest interest for glaucoma is the new range of micro “bypass stent” inserted via the anterior chamber directly into the trabecular meshwork, to reduce intraocular pressure. This will augment his already wide experience in selective laser trabeculoplasty for glaucoma. Mr Calladine has a passion about patients being actively involved in their glaucoma care, in particular reviewing progression data mapping, to ensure stability in the condition.
