Repeatability in Measurements of Two ssOCT and One OLCR Biometer

Cataract Senile Clinical Trial

Official title:
Evaluation of Repeatability in Measurements of Two Swept-source Optical Coherence Tomography (Ss-OCT) Biometers and One Optical Low Coherence Reflectometry (OLCR) Biometer

Clinical Trial Summary

Achieving high accuracy and precision in ocular biometry has become primordial for cataract surgery, due to the shift of cataract surgery from a rehabilitation procedure to a refractive one.

Aim of this study is to determine the repeatability of ocular biometric parameters obtained using three biometry devices, two ss-OCT biometers and an OLCR device.

Clinical Trial Description

Accurate and repeatable biometric measurements are essential in providing an optimal refractive outcome.

ss-OCT biometry uses a tunable wavelength laser source to scan the eye, this technology showing its superiority through better signal-to-noise ratio, the wavelength light source being projected into the eye, one at a time; thus improving tissue penetration.

This a prospective observational study that would include patients which attended pre-surgical examination. A written informed consent will be obtained from each patient.

Only one eye from each patient will be included in the study. All patients included in the study will undergo biometric measurements in a random fashion with the three devices (IOLMaster 700, Lenstar LS 700 and Anterion Heildelberg). Each patient will be measured three times with each device and between the measurements they will be asked to blink or keep their eyes closed for tear film recovery and to avoid fatigue. Scans that pass the quality requirement of each device will be taken for analysis. ;
