Anterior segment optical coherence tomography (OCT) has become an important tool for evaluating the cornea and the anterior segment or front portion of the eye. Cross sectional tissue images of these ocular structures can be generated in vivo, for detailed analysis.
The clinical applications of anterior segment OCT are extremely important and useful. Cross-sectional images of the cornea, anterior chamber, crystalline lens and iris can be obtained in a manner that no other technology can provide. These images can be invaluable in the diagnosis and management of many anterior segment diseases and conditions such as keratoconus, corneal transplants, corneal ectasia, narrow angle glaucoma, and many other corneal dystrophies and degenerations.
In addition to the above uses of this technology, our specialty lens practice uses optical coherence tomography to assist us in gaining a better understanding of many of the complex corneal conditions that we see and treat. We are using OCT technology to help us create more sophisticated scleral lens designs for specific corneal conditions and diseases. Our goal is to use this technology and new emerging technologies that we possess to allow our “hi need” patients regain useful functional vision along with excellent comfort.
Note in the attached images how the OCT allows the fit of the lens to be assessed at all points along the cornea and sclera.
