Cataract Diagnostic Technology

Konan Specular Microscope

The Konan Specular Microscope is a unique device that can accurately measure a patient’s endothelium cell thickness. It can help us determine if a patient might have endothelium cell damage, which could lead to vision loss. The endothelial cells are the inner most layer of the cornea and can be as thin as one cell thick. They maintain the eyes fluid balance to ensure clear vision. Unlike most cells in the human body, endothelial cells cannot replicate. With certain eye diseases like Fuchs’ dystrophy, the endothelial cells become damaged and turn cloudy, causing visual loss.It is also an excellent tool that screens for corneal disease (fuchs-guttata, kerataconus, trauma, etc.).

Zeiss Atlas Topography

The Zeiss Atlas Topographer provides our doctors with the data needed to determine the health of a patient’s cornea. The cornea is the clear “window” on the front surface of the eye. It’s one of the two main focusing lenses of the eye. This technology can detect corneal dystrophies, astigmatism, irregular astigmatism, pellucid degeneration and other diseases such as keratoconus. The Zeiss Atlas topographer is also no-touch, and only takes a few minutes to perform.

Zeiss Cirrus OCT (Posterior segment)

San Antonio Eye Specialists is excited to offer the Cirrus OCT manufactured by Carl Zeiss, to our patients. This OCT or (Ocular Coherence Tomography) is used to take high-resolution images and measurements of the optic nerve, fovea, retina, and cornea. These 3-D images can be used to diagnose eye diseases such as macular degeneration, diabetic retinopathy and glaucoma. This is one of the most advanced posterior segment diagnostic devices available. It can take over 27,000 images at one time, versus 400 with previous models.

The test only takes a few minutes and is non-contact, so there is no discomfort.

Zeiss IOL Master

At San Antonio Eye Specialists, we offer our cataract patients the precision of the Zeiss IOL Master. This advanced technology allows our surgeons to take precise measurements within the eye, which ensures the most accurate measurements for selecting the appropriate intraocular lens power for our patients’ undergoing cataract surgery in San Antonio. Choosing the right lens is critical for good visual outcomes.
