Summary

Optical interferometric biometry is a non-invasive and highly precise method for measuring eye length and intraocular distances. The method already exists as commercial devices (e.g. IOLMaster, Carl Zeiss Meditec AG). A major cost factor of the devices available on the market is the laser used. The use of a much cheaper laser could significantly reduce the price of these devices, which would lead to greater availability of this technology in developing countries. This would make it possible to replace the ultrasound methods used to date and thus enable contact-free measurements, which in turn can reduce the spread of infectious diseases.The study investigates the use of a thermally tunable vertical cavity surface emitting laser (VCSEL) for optical swept source biometry.

Conditions

  • Cataract
  • Myopia

Interventions

DEVICE

Biometry

Only one eye from each patient will be included in the study. All subjects and patients included in the study will undergo biometric measurements with both devices (IOL master 500 and VCSEL based swept source optical biometry).
