Title:
OPHTHALMIC DEVICE AND METHOD FOR CONTROLLING OPHTHALMIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/048209
Kind Code:
A1
Abstract:
Provided are an ophthalmic device and a method for controlling an ophthalmic device with which it is possible to easily generate satisfactory three-dimensional data of an observed portion of an eye under examination. The present invention is provided with: a pre-scan control unit (216) for performing a pre-scan on the observed portion (eye fundus (Ef)); a tomographic shape acquisition unit (218) for detecting or predicting the tomographic shape of the observed portion; a main scan control unit (220) for controlling an optical scanner and executing a main scan on the observed portion; an optical path length acquisition unit (214) for acquiring the optimum optical path length at a specific scan position of the main scan at least before the main scan; an optical path length adjustment control unit (224) for controlling, during the execution of the main scan, an optical path length changing unit and adjusting the optical path length to the optimum optical path length; and a three-dimensional data generation unit (226) for generating three-dimensional data (404) of the observed portion.
