Okla. Stat. tit. 85A, § 85A-114: Prosthetic devices

When a compensable injury results in the loss of one or more

eyes, teeth, or members of the body, or the replacement of a joint,

the employer shall furnish such prosthetic devices as may be

necessary as determined by the Workers' Compensation Commission in

the treatment and rehabilitation of the injured worker for the

lifetime of the worker. When a worker sustains a compensable

injury, arising out of and in the course of his or her employment,

which results in damage to a prosthetic device with which such

worker is equipped, the employer shall repair or replace such

device. Provided, that a subsequent injury to the part of the body

for which a prosthetic device is provided shall terminate the

obligation of the employer to provide such prosthetic device.
