An intraocular lens state analysis apparatus and program that can easily determine the state of an intraocular lens in the eye. A control unit 2 of an OCT apparatus 1 as an intraocular lens state analysis apparatus acquires tomographic images at a plurality of positions of an eye into which an intraocular lens is inserted from a measurement unit 3 or a storage unit 11, and A lens tilt line indicating the tilt direction of the intraocular lens is set for each acquired tomographic image. A plurality of points are set equally on the lens tilt line as equal division points. The distance between each end point of the lens tilt straight line and the reference line defined by the direction between the corners is calculated. A color in which the gradation gradually changes from an end point with a larger distance of the lens inclination straight line toward an end point with a smaller distance is assigned to each equally divided point. The color of each equally divided point is reflected on a map obtained by viewing the intraocular lens in plan view, and the map is displayed. In addition, tomographic images at a plurality of time points at the same position of the same eye to be examined are acquired, and an image obtained by synthesizing the tomographic images at the plurality of time points after matching the positions of predetermined portions is generated. [Selection] Figure 1【課題】眼内レンズの眼内での状態を容易に判断できる眼内レンズ状態解析装置及びプログラムを提供する。【解決手段】眼内レンズ状態解析装置としてのＯＣＴ装置１の制御部２は、眼内レンズが挿入された眼の複数の位置での断層像を測定部３又は記憶部１１から取得して、取得した断層像毎に眼内レンズの傾き方向を示したレンズ傾き直線を設定する。レンズ傾き直線上に均等に複数の点を均等分割点として設定する。レンズ傾き直線の各端点と、隅角間の方向で規定される基準線との距離を演算する。レンズ傾き直線の前記距離が大きい方の端点から小さい方の端点に向かって徐々に濃淡が変化する色を各均等分割点に割り振る。割り振った各均等分割点の色を、眼内レンズを平面視で見たマップに反映させ、そのマップを表示する。また、同一被検眼の同一位置での複数時点の断層像を取得して、複数時点の断層像を所定部位の位置を一致させたうえで合成した画像を生成する。【選択図】図１
