Summary

The purpose of this study is to report the prevalence data for total corneal astigmatism (TCA) in cataract surgery candidates.

Conditions

  • Cataract

Interventions

DIAGNOSTIC_TEST

IOLMaster 700

The IOLMaster 700, one of the most commonly used optical biometers for IOL power calculation, measures the anterior corneal surface radius using a telecentric keratometry. Additionally, it employs swept-source optical coherence tomography (SS-OCT) technology to simultaneously measures the posterior cornea surface radius and central corneal thickness (CCT). The AK formula, described by Abulafia et al., is a regression formula that calculates an estimated TCA using K astigmatism. The Barrett toric calculator uses an unpublished mathematical prediction method of TCA based on anterior corneal measurements.
