OCULAR BIOMETRY

We use our A / B Scan ultrasound equipment, IOL Master and Pentacam Scheimpflug Rotating Camera system to examine the internal anatomy of the eye. Ocular ultrasounography employs the same principle technologies used in fetal ultrasound, although on a smaller scale. The sound beam delivered is reflected at interfaces of differing tissue densities and the reflected beam is received by the transducer. The reflected sound waves are analyzed to give further information about ocular structures. The transducer is placed directly on the eye with a soft contact lens in between, or on the eyelid, depending on the desired procedure. The IOL Master has the latest technology in A scan ultrasonography, which takes accurate axial length measurement of the eyeball, without the need for contact (nothing touches the eye itself), therefore without the need for anesthesia and no potential for spread of contamination. The Scheimpflug rotating camera system of the Pentacam allows sharp, crisp images of the anterior eye segment to be captured, which includes information from the anterior cornea to the posterior lens capsule.

With these tools, we are able to measure corneal thickness, anterior chamber angle, anterior chamber depth of the eye, the axial length of the eyeball, and evaluate the posterior structures of the eye in the case of dense opacities obscuring our view. The measurement of corneal thickness is necessary in glaucoma management, extended wear of contact lenses and to check if individuals are suitable for lasik surgery (if corneas are too thin, and myopia too high lasik is not suitable). The measurement of the anterior chamber angle and depth is also necessary in glaucoma management. With the Scheimpflug camera system, such measurements are a lot easier, faster and accurate than traditional methods where the use of local anesthetic and uncomfortable lenses are applied to the front surface of the eye. B-scan ultrasound displays the internal anatomy of the eye, allowing for evaluation of the retina when it is obscured by media opacities, as in the case of dense cataract and vitreous haemorrhage. B-scan ultrasound is also integral in the evaluation of ocular tumors and a variety of other ocular disorders.
