Claim:
1. An ophthalmologic apparatus, comprising: an optical system including a light beam projecting unit for projecting a light beam to an eye to be inspected, and a light receiving unit for receiving a reflection light beam obtained by reflection of the light beam on the eye to be inspected; a detecting unit for detecting a plurality of bright spot images from the reflection light beam received by the light receiving unit, the bright spot images being generated based on the light beam reflected by an intraocular lens provided in the eye to be inspected and the light beam reflected by a cornea of the eye to be inspected; a determining unit for determining whether or not each of the plurality of bright spot images is generated based on the reflection light beam obtained by reflection on a cornea of the eye to be inspected, in accordance with a position of the bright spot images being generated based on the light beam reflected by the intraocular lens and a position of the bright spot images being generated based on the light beam reflected by a cornea of the eye to be inspected in a direction of an optical path of the optical system; a selection unit for selecting bright spot images, which are a part of the detected plurality of bright spot images and are determined by the determining unit to be based on the reflection light beam obtained by the reflection on the cornea; and a calculating unit for calculating an alignment status between the eye to be inspected and the optical system based on the bright spot images selected by the selection unit, wherein a bright spot image which is not selected by the selection unit is not used for calculating the alignment status.
