What is it indicated for?

The IOLMaster 700 is intended for biometric measurements and visualization of ocular structures. The measurements and visualization assist in the determination of the appropriate power and type of intraocular lens. The IOLMaster 700 measures:

• Lens thickness

• Corneal curvature and thickness

• Axial length

• Anterior chamber depth

• Pupil diameter

• White-to-white distance (WTW)

For visualization, the IOLMaster 700 employs optical coherence tomography (OCT) to obtain two-dimensional images of ocular structures of the anterior and posterior segments of the eye.

The Reference Image functionality is intended for use as a preoperative and postoperative image capture tool.

Indications for use as stated in the FDA summary.
