Abstract
An ophthalmic laser treatment apparatus includes a light interference optical unit, an irradiation unit, a luminance transition information detecting unit, a focused state detecting unit, and a guide unit. The light interference optical unit is configured to acquire a depth profile of a patient's eye tissue. The luminance transition information detecting unit is configured to control a first focus position adjusting unit to shift a focus position of a measurement light to acquire a depth profile in each focus position. The focused state detecting unit is configured to detect a focused state in the patient's eye tissue based on luminance transition information acquired by the luminance transition information detecting unit. The guide unit is configured to guide a focus position of a laser beam to be adjusted based on a result of detection of the focused state detecting unit.
