In simple words: A special lens device monitors a patient's eye pressure for a day or more. The provider analyzes the data and creates a report with the results.

A specially made contact lens is placed in one eye or in each eye to monitor the patient's intraocular pressure (IOP) for 24 hours or more. The data is transmitted via an antenna to a portable recorder. The stored data is then transmitted to the provider's computer with relevant software installed, and the provider reviews and interprets the data to assist with treatment of glaucoma patients. The provider prepares a report of the findings.

Example 1: A patient with suspected glaucoma undergoes 24-hour IOP monitoring using a contact lens device to evaluate the fluctuations in eye pressure throughout the day and night., A patient with diagnosed glaucoma who is not responding well to current treatment undergoes IOP monitoring to assess the effectiveness of the therapy and guide adjustments., A patient with a history of normal-tension glaucoma undergoes IOP monitoring to determine if there are significant pressure spikes contributing to the disease progression.

Documentation should include the duration of the monitoring, the method used (contact lens device), the interpretation of the pressure readings, and the clinical findings related to the patient's condition.
