IOL Power Calculation/Biometry Part I Keratometry ( follow quickguide.org )

Biometry for #iols power calculation for #cataractsurgery - In this series on #Biometry for IOL power calculation, Part I focuses on Keratometry. Biometry for IOL power does not involve only IOL power calculation, but also involves Effective Lens Position determination. Therefore, determination of IOL power and #ELP are equally important for better refractive outcome. Part I focuses on the importance of Keratometry, the concept of Keratometry Index, the conversion of radius of curvature to dioptric power of cornea, etc. It also explains why a patient corneal reading may vary between two or more different Keratometers, and how different keratometry machines measure different rings of cornea. #iols #topography #eyesurgery #intraocularlens #education
