• Convex-surfaced contact lenses increase the power of the laser optically for surgery on the iris. Their power-increasing faculty becomes obvious by their power of image magnification. When linked by functions, lens power, laser power, and magnification increases. The laser power, which is multiplied by the lenses, contains a safety feature for the tissues outside the focus of the laser beam as the beam increases in angle. Safety and power is gained by the appropriate use of powermultiplying contact lenses for argon laser surgery.
