PURPOSE: To determine whether residual myopia could be corrected postoperatively using the light-adjustable lens (LAL) technology in patients undergoing cataract surgery and LAL implantation. DESIGN: A prospective clinical study was conducted at Codet Vision Institute in Tijuana, Mexico. The LALs were implanted that would purposely result in myopic errors of up to -1.5 D (diopter). The LAL was treated with a spatial intensity profile delivered by a digital light delivery device to induce a targeted myopic refractive change. Once the desirable myopic correction was achieved, the LAL was treated again to lock-in the lens power. PARTICIPANTS: Fourteen eyes of 14 patients were studied. METHODS: The manifest refraction, uncorrected visual acuity (UCVA), and best- or spectacle-corrected visual acuity (BCVA), were measured with follow up time of 1 to 9 months to determine the achieved refractive corrections and their stability.
