Laser therapy in cataract surgery.

: In the more than 25 years since the development of ultrasound phacoemulsification, enormous change has occurred in cataract surgery. One of the latest and most significant changes in cataract surgery has been the development of devices that utilize laser energy for the removal of cataracts. Both ultraviolet (excimer) and infrared wavelengths have been studied, but in 1994, we have seen significant progress only with the infrared wavelengths. The lack of progress in the devices utilizing ultraviolet wavelengths are due to concerns with safety. Two infrared laser devices, one developed by Dodick and the other developed by Colvard have been used successfully for the removal of cataracts under Investigational Device Exemptions from the Food and Drug Administration. These developments have brought us a step closer to realizing the dream of laser cataract surgery.
