Interventions
Learn about the drugs, procedures, or behavioral strategies being tested and how they are applied within this trial.
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The Barrett toric calculator uses an unpublished mathematical prediction method of TCA based on anterior corneal measurements.
