Title:
OPHTHALMIC DEVICE AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2019/003804
Kind Code:
A1
Abstract:
This ophthalmic device comprises: an SLO system; a projection system; a first image forming unit; a second image forming unit; a displacement processing unit; and a control unit. The SLO system scans the eye of interest with first light deflected by a first light scanner. The projection system projects second light deflected by a second light scanner onto the eye of interest. The first image forming unit, on the basis of the result of scanning a first scan region with the first light scanner, forms a first image of the eye of interest. The second image forming unit, on the basis of the result of scanning by means of the first light scanner of a second scan region narrower than the first scan region, forms a second image of the eye of interest. The displacement processing unit calculates a displacement between a partial image of the first image corresponding to the second image and the second image. The control unit, on the basis of the calculated displacement, controls the second light scanner.
