Abstract:
Measurements of dimensions of various intraocular structures, both normal and abnormal, are both theoretically and clinically useful. The currently available standard Haag-Streit slit-lamp micrometer eyepiece is calibrated at 100 micron intervals. In order to achieve greater precision in measurement of smaller intraocular structures, the authors and Haag-Streit, Inc. (Kaniz, Switzerland) have developed an eyepiece calibrated in 50-micron intervals.
