Anterior Segment OCT

Optical coherence tomography (OCT) allows us to obtain high-resolution cross-sectional images of the anterior and posterior segment of the eye in a non-invasive way using optical interferometry. It has now become a very useful tool for the ultrastructural study of ocular anatomy.
The 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 filter surgery. In the field of cataract surgery, OCT allows us an accurate analysis of the architecture of the incisions, as well as the relationships between the intraocular lens and the posterior capsule.
The 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. In addition, it allows us to determine corneal and epithelial pachymetry, quantify the value of the irido-corneal angle, quantify the anterior chamber depth, assess the positioning and alignment of phakic and pseudophakic intraocular lenses, and study the contact lenses on the cornea and the state of the ocular surface, and is also useful for the study of dry eye.
