Course Details

February 9^th

May 17^th

Surgeons (residents included), optometrists and technicians eager to learn biometry and IOL Power Calculations to improve cataract outcome.

Acquire knowledge on different aspects of biometry and IOL Power Calculations to optimize patient outcomes.

• Dr. Miguel Raimundo

Why good biometry is important
Common sources of error, different components for IOL Power calculation Effective Lens Position (ELP) Lens Constant – What is it and is it possible to optimize? How can you work with it and improve your lens choice?
Understanding axial length measurements
Steps to acquire good measurements Commons mistakes to avoid and understanding validation criteria
Understanding astigmatism
Understanding astigmatism Role of posterior corneal astigmatism Understanding Surgical Induced Astigmatism (SIA) and calculation
Choosing post-operative target refraction case scenarios for discussion
Normal cases from daily practice Case studies for interaction

Understanding your diagnostic devices
Biometer – acoustic contact, immersion, optical biometer SS-OCT Topographers (basics of topography in relation to biometry)
Understanding corneal power measurements (keratometry)
Understand how keratometry is measured in different equipment (if it is anterior keratometry or total corneal power keratometry) Understand the relation between anterior and posterior Steps to acquire good measurement Common mistakes to avoid and understanding validation criteria
