The present invention provides a system and a method for performing a cataract surgery. The system of the present invention includes an optical coherence tomography apparatus, an image capturing device, and a central processing unit. The method includes imaging optical coherence tomography of a patient's eye using the optical coherence tomography apparatus, capturing the patient's optical coherence tomography with the image capturing device, generating a 3D image and coordinates of the patient's eye, and determining a central location of a pupillary margin and an iridocorneal angle using a central processing unit. The center of the anterior capsule of the human crystalline lens is then calculated by matching the iridocorneal angle to the central location of the pupillary margin.

It is provided a method for quick switching to realize anterior and posterior eye segments imaging, which can realize quick switch and real-time image for locations at different depths. On one hand, with an ability of quick switch, objects at different depths can be measured, and the detection scope of the OCT system can be enhanced; the switch system is able to work stably and change positions accurately without influencing the signal-to-noise ratio of the system. On the other hand, the light beam can be respectively focalized at different locations. Thus, high quality of anterior and posterior eye segments imaging can be achieved with a relatively high lateral resolution for human eyes having different ametropia. Furthermore, based on the anterior and posterior eye segments imaging, an ability of real-time eye axial length measurement can be added.

An embodiment provides a technology for preventing a situation in which a subject's eye is imaged in an inappropriate imaging mode. An ophthalmic apparatus according to one embodiment is capable of selectively performing a first imaging mode and a second imaging mode. The first imaging mode is an imaging mode in which imaging of a subject's eye is performed in a first state where an attachment unit is not attached. The second imaging mode is an imaging mode in which imaging of the subject's eye is performed in a second state where the attachment unit is attached. The ophthalmic apparatus according to the embodiment includes the followings: an operation unit configured for designating an imaging mode; an attachment state determination unit configured to determine whether or not the attachment unit is attached; a correspondence determination unit configured to determine whether or not the correspondence between the imaging mode designated by a use of the operation unit and an attachment state of the attachment unit obtained by the attachment state determination unit is appropriate; and a controller configured to perform control for prohibiting imaging in at least the designated imaging mode when the correspondence determination unit has determined that the correspondence is not appropriate.

What is provided are methods of analyzing at least one image of the anterior segment of an eye and for selecting an intraocular lens (IOL). The methods may include detecting at least one image from an anterior segment of the eye; identifying a location of a reference structure on the eye using a plurality of points of a landmark on the anterior segment of the eye; and calculating at least one quantitative dimension of the anterior segment of the eye using the reference structure. The newly identified landmarks and quantifiable dimensions improve the characterization of the anterior segment in order to better predict the position and movement of the intraocular lens. The improved methods for analyzing the imaging of the anterior segment of the eye allows for improvements in the refractive outcomes of cataract surgery, glaucoma procedures, refractive outcomes, and other eye-related diseases.
