Laser therapy in cataract surgery

Since the development of ultrasound phacoemulsification more than 25 years ago, cataract surgery has changed dramatically. One of the major changes in cataract surgery has been the research into the use of laser for the removal of cataracts. To date, both ultraviolet and infrared wavelengths have been studied, with the infrared showing more promise. The ultraviolet end of the spectrum has shown promise, but concerns with safety have hindered its progress. An infrared laser device developed by Dodick has been used successfully for the removal of cataracts under an Investigational Device Exemption from the Food and Drug Administration and a second infrared laser developed by Colvard should be approved soon. These developments have brought us a step closer to realizing the dream of laser cataract surgery.
