We have developed a simple, accurate, objective and quick confocal fiber-optic laser method for exact dioptric power measurement of both positive and negative intraocular lenses providing spatial resolution better than 1 mum under simulated in-situ conditions.
Based on a fiber-optic confocal design, we have developed a simple, accurate, objective and quick method for exact focal length measurement of both positive and negative intraocular lenses providing a spatial resolution exceeding 1 mum.
