Refractive Multifocal IOLs Explained | Annular vs Segmental Designs

Refractive multifocal intraocular lenses (IOLs) represent a pivotal advancement in modern cataract and refractive surgery. Designed to restore vision at multiple distances, these lenses provide an alternative to diffractive and EDOF technologies. In this comprehensive lecture, you will gain a clear understanding of the optics, clinical performance, advantages, and limitations of refractive multifocal IOLs. From classic concentric annular designs to modern segmental platforms like the FEMTIS and Lentis Mplus, this video offers high-yield insights for ophthalmologists, residents, and optometrists. 🔬 What You’ll Learn: Principles of simultaneous focality and neuroadaptation Optical design of refractive multifocal IOLs Concentric (annular) vs segmental (asymmetric) lenses Visual outcomes: distance, intermediate, and near vision Pupil dependency and decentration sensitivity Photic phenomena: glare, halos, and contrast sensitivity Clinical indications and patient selection Advances in FEMTIS and modern capsulorhexis-fixated lenses Comparison with diffractive multifocal IOLs 👁️ Featured IOL Platforms: Lentis Mplus FEMTIS Mplus Rayner M-Flex ReZoom and Array This video is ideal for cataract surgeons, ophthalmology residents, and anyone preparing for FRCS, ICO, or board examinations. 👍 If you find this helpful, please like, share, and subscribe for more high-yield ophthalmology content. #Ophthalmology #MultifocalIOL #CataractSurgery #RefractiveSurgeryJoin this channel to get access to perks: https://www.youtube.com/channel/UCCgorR4a_gth3qGrM6O_hag/join
