Intraocular Lens Calculation Using Artificial Intelligence
Sponsor: Johannes Kepler University of Linz
Summary
The aim of this study is to investigate the lens diameter (LD) as a useful parameter in intraocular lens (IOL) power calculation by using several different non-invasive imaging techniques. The aim is to establish an accurate model for lens diameter estimation and subsequently evaluate the influence of the LD on the effective postoperative lens position. The comparability of the different devices in terms of variability between the biometric measurements will also be assessed. By then combining these two approaches with artificial intelligence, the aim is to develop a new approach to effectively incorporate the LD in IOL power calculation and improve patient's outcome in the long run.

Interventions
Swept-Source Anterior Segment OCT
Device: Swept-Source Anterior Segment OCT The CASIA-2 (Tomey, Japan) is a high-resolution swept-source anterior segment OCT with CE certification. The device allows for incomplete visualization of the lens, including the anterior and posterior lens curvature. Device: AS-OCT + Placido disc corneal topography The MS-39 (CSO, Italy) is a non-invasive device that combines Placido topography with OCT-based anterior segment tomography. Device: Wave-front abberomtery The OSIRIS aberrometer is a standard tool for examining corneal aberration and measuring the ocular wavefront. Device: Swept-Source OCT The IOLMaster 700 (Carl Zeiss Meditec, Germany) is a standard swept-source OCT used for eye examinations. Device: AS-OCT The ANTERION (Heidelberg Engineering, Germany) is an anterior segment swept-source OCT. Diagnostic Test: Refraction Subjective Refraction evaluation using the cross-cylinder method
