This document provides a comprehensive nomogram and pre-surgical planning guide for Intacs corneal implant surgery. It includes:
1. A nomogram to select symmetric or asymmetric Intacs segments based on the patient's manifest refraction and topography results.
2. Guidelines for pre-surgical planning, including measuring manifest refraction, best corrected visual acuity, corneal topography, and pachymetry.
3. Definitions for steep and flat meridians to identify the appropriate location for incisions.
The goal is to assist surgeons in the initial case planning process for Intacs surgery using best practices developed from experience with thousands of cases. Additional guidance is available online.
