Anterior Segment Optical Coherence Tomography

It is the most advanced device for the analysis of the anterior segment of the eye. MS-39 combines Placido disc corneal topography with high-resolution OCT-based anterior segment tomography. The clarity of the cross-sectional images, with a diameter of 16 mm, along with the many details of the corneal structure and layers revealed by MS-39, will be appreciated by anterior segment specialists. MS-39 provides information on pachymetry, elevation, curvature, and dioptric power of both corneal surfaces. In addition to anterior segment clinical diagnostics, MS-39 can be used in corneal surgery for refractive surgery planning. An IOL calculation module is also available, based on ray tracing techniques. Additional tools allow the MS-39 to perform precise pupil diameter measurements and advanced tear film analysis.

Optical coherence tomography (OCT) allows us to obtain high-resolution cross-sectional images of the anterior and posterior segment of the eye non-invasively using optical interferometry. Currently it has become a very useful tool for the ultrastructural study of ocular anatomy. Anterior segment OCT is used in the follow-up of patients undergoing refractive surgery, intrastromal rings, corneal cross-linking, corneal transplants, phakic intraocular lenses, and in patients undergoing glaucoma filtering surgery. In the field of cataract surgery, OCT allows us a precise analysis of the architecture of the incisions, as well as the relationships between the intraocular lens and the posterior capsule. Anterior segment OCT is very useful in the analysis and evaluation of tumors and cysts of the anterior segment, conjunctival tumors and different corneal conditions such as dystrophies, degenerations or infections.
