In 15 eyes, no valid ACD readings could be obtained with the OLCR device. No obvious reason for these measurement failures was identified; however, tear-film alterations shortly after surgery were suspected. No significant difference in the mean ACD in the remaining 50 eyes was found between PCI measurements (5019 ± 660 μm; range 4008 to 6181 μm) and OLCR measurements (5015 ± 663 μm; range 4017 to 6163 μm) (P = .06).

The OLCR device proved to be more user-friendly and faster; however, in a substantial number of eyes, no usable values were obtainable.FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned.",
