Exact Opticsimitations and constraints of paraxial geometrical optics and describe geometrical aberrations. Optical aberrations can be expressed in terms of wavefront aberrations due to the wave nature of light. Hence, this model provides us with figures of merit that describe the quality of optical systems in

Demographics of Biometry over 80,000 eyes including all races and ages. It is an important update to the first such series of 7500 eyes by Hoffer (using immersion A-scan) more than 40 years ago. There are differences between the sexes (males have longer axial lengths and flatter corneas than females) and among racial group

Optical Biometrye of the essential variables for the calculation of the intraocular lens (IOL) power. In this chapter, the technologies of the different interferometric setups are described in detail: from PCI to OLCR, finally arriving at the present day used swept-source OCT. The accurate measurement of anterior c

Technology of SS-OCT Biometer: Argos Biometerhe biometric parameters necessary for IOL power calculation. Swept-source OCT technology allows two-dimensional imaging, a superior signal-to-noise ratio, and improves tissue penetration and image quality. The Argos biometer calculates axial length as the sum of physical distances of four segments:
