The new edition has been extensively revised by internationally renowned experts to incorporate the latest advances in ophthalmic care while retaining its practical approach and compact design. Comprising 15 chapters, the book comprehensively covers a vast array of eye conditions offering step by step guidance on how to perform common ocular procedures from intravitreal injections to cataract surgery. Descriptions of procedures appear in discrete boxes, making them more prominent and accessible. Each chapter tab is colour coded to improve navigation. All content has been updated in line with current best practice. Key studies sections summarise landmark trials and their relevance to clinical practice. The triage chapter provides multiple diagnostic decision-making algorithms based on common signs and symptoms, and then refers readers to the relevant sections on management, explaining specific treatment regimens covering all important eye conditions.
