Abstract:
1. An apparatus for measuring ocular axial length, comprising: a measuring unit having a first irradiating system which irradiates measurement waves onto a fundus of an examinee's eye through a cornea of the examinee's eye, a first detector which detects reflected waves including waves reflected from the fundus, and a first calculation part which calculates ocular axial length of the examinee's eye based on detection signals output from the first detector, wherein the first calculation part acquires reflection information related to an anterior segment of the examinee's eye, extracts reflection signals corresponding to a reflection object between the cornea and a posterior capsule of a crystalline lens of the examinee's eye based on the acquired reflection information, and determines whether the examinee's eye is a phakic eye or an IOL eye based on the extracted reflection signals.
