Sandstedt CA, Chang SH, Grubbs RH, Schwartz DM, Light-adjustable lens: customizing correction for multifocality and higher-order aberrations. Thank you! A lens great for general photography from interiors, to landscapes and portraits. A clear advantage in achieving emmetropia in standard cases but something that can be invaluable for the increasing number of post-refractive cataract surgery patients. Following this polymerisation, macromers in the peripheral, un-irradiated portions of the LAL are highly concentrated relative to the central irradiated zone, where they have been depleted by irradiation. This creates a thermodynamically unstable diffusion gradient, which is corrected over 12 to 15 hours as macromers diffuse toward the irradiated region to once again establish uniform concentration throughout the matrix. Images may be blurred, Light Adjustable lens. The best number for every other lens is about 70%, he said.
