Corneal Scars - (Irregularities of the Corneal Surface)

This is the same eye as shown in Keratometer Tips, bottom of page.

Scars and local irregularities of the anterior cornea impair the image quality of the optical section of the cornea. Depending on the extent and degree of these irregularities, this may lead to measuring errors.

In such a case, the fixation point is imaged as a "cloud" and it is impossible to improve the adjustment. If apparently plausible anterior chamber depth results are nevertheless displayed, they can only be regarded as reference points.

WARNING: To obtain reliable data, all the other known facts and findings of this eye should be included in the evaluation.
