  • Page 3: Introduction

    Note; This is applicable to California, U.S.A. only [WARNING] The safety and effectiveness of the Wave-front Analyzer KR-1W has not been estabrished for use of the device as an accessory interfaced to the refractive laser for the treatments of the higher order aberrations of the eye by photorefractive keratectomy(PRK), phototherapeutic keratectomy (PTK), or laser assisted in situ keratomileusis (LASIK).
  • Page 4 To avoid injury in changing the measurement mode, do not place fingers into the measuring opening. To avoid electric shock, do not open cover. For repair, ask a certified Topcon Service Engi- neer. When changing the fuse, turn off the power, and disconnect the power cable. Use the properly rated fuse.
