Instructing the right expert is often the decisive step in an ophthalmic claim. This article explains what a medicolegal expert witness in ophthalmology does, the legal framework that governs their work, the process of instruction, and the pitfalls that most commonly arise in clinical negligence litigation.
What is a medicolegal expert witness?
A medicolegal expert witness is a medical professional with specialist knowledge who is instructed to provide an independent opinion for the court on matters within their expertise. In clinical negligence or personal injury cases, their role is not to advocate for either side but to assist the court in understanding complex clinical evidence and determining whether the standard of care was met. In ophthalmology, expert evidence is frequently sought in claims involving delayed diagnosis, for example of retinal detachment or glaucoma; surgical complications in cataract, LASIK, or oculoplastic procedures; visual impairment arising from trauma or systemic disease; and allegations of substandard consent or documentation.
The legal framework: CPR Part 35 compliance
Expert witnesses in the UK operate under the Civil Procedure Rules Part 35, which mandates that the expert's overriding duty is to the court, not to the instructing party. The expert must provide a reasoned opinion that is independent and impartial, based on current clinical guidelines and peer-reviewed literature, and transparent about limitations or uncertainties in the evidence. At Medicolegal Chambers, all reports adhere strictly to CPR Part 35 and incorporate the Model Terms of Engagement recommended by the Academy of Experts.
The process of expert instruction
When instructing an expert witness in ophthalmology, solicitors typically follow a structured process. It begins with an initial enquiry and CV review to ensure the scope of expertise aligns with the case, followed by a letter of instruction setting out the facts, issues, and questions to be addressed. The expert then undertakes a disclosure review of medical records, correspondence, and relevant imaging, before preparing a report covering breach of duty, causation, and condition and prognosis as appropriate. Where cases proceed to court, this may extend to a joint statement and oral evidence. Clear timelines, transparent fee schedules, and ongoing communication are vital throughout, and our Terms of Business set out these expectations at the outset of every instruction.
Common pitfalls in ophthalmic litigation
Drawing on more than twenty years of clinical and medicolegal experience, common areas of ophthalmic litigation include missed diagnosis of retinal detachment or endophthalmitis, intraoperative complications in cataract surgery, laser eye surgery consent failures, failure to refer or escalate urgent cases, and inadequate documentation of follow-up care. Each of these scenarios demands expert scrutiny to distinguish between an unfortunate outcome and a breach of duty.
