2026-2027 Basic and Clinical Science Course, Section 3

BCSC Section 3, Clinical Optics and Vision Rehabilitation, of the Academy's Basic and Clinical Science Course™ (BCSC®) provides a comprehensive overview of clinical optics and clarifies, for ophthalmology residents and practicing ophthalmologists alike, how optical principles translate into clinical practice. Notable Revisions to BCSC Section 3 include: Updated and expanded discussion of the prevention of myopia progression Revised discussion of IOL power calculation formulas, including optimization, IOL constants, and potential sources of error Expanded discussion of IOL power calculation in atypical eyes, such as silicone oil eyes, eyes with keratoconus, and more Detailed coverage of currently available monofocal, toric, and presbyopia-correcting IOLs Several original figures illustrating aspects of physical optics, such as wavefront aberrometry, and higher-order aberrations (sample) Inside This Section: Explains the fundamental principles of light, refraction, and image formation, with clear connections to real-world clinical applications Begins with a Quick-Start Guide covering optics, refraction, and retinoscopy, which includes step-by-step instructions, clinical examples, and “Try It Yourself!” exercises to reinforce learning Covers geometric and physical optics, optics of the eye, and core concepts in refraction Reviews approaches to diagnosing and managing refractive error Explores advances in optical correction, such as contact lenses, spectacles, intraocular lenses (IOLs), and refractive surgery techniques Includes a dedicated chapter on vision rehabilitation, focusing on tools and technologies for patients with visual impairment 13 videos, including the new video on Surgical insertion of the CentraSight IMP and three new interactive activities Who This Book Is For: Ophthalmology residents building their optics knowledge and preparing for exams Fellows and early-career ophthalmologists refining refraction and optical decision-making Practicing ophthalmologists seeking a refresher on optics and vision rehabilitation Why Use BCSC Section 3: Developed by the American Academy of Ophthalmology Comprehensive yet organized for efficient study Combines theory with hands-on, practical learning tools Used as a core resource in ophthalmology training programs worldwide
