Abstract

Abstract : Purpose: To determine the long-term safety and effectiveness of a light-adjustable intraocular lens (LAL) over a period that is longer than reported in the literature at the time of the study. Setting: University Eye Hospital, Bochum, Germany. Design: Noninterventional observation. Methods: In 445 patients, cataract surgery with LAL implantation was performed between April 2008 and December 2012. It was possible to contact 171 of these patients or their relatives through letter or telephone; 61 patients (103 eyes) agreed to participate in the long-term study and were examined. Results: The mean time between the lock-in (final light treatment) and long-term visit was 7.2 years; 61 patients were included and examined. Corrected and uncorrected distance visual acuity was and remained good (n = 93). The refractive outcome was stable with minimal deviation. There were no significant changes in corneal thickness. In 2 patients, there were slight opacities of the IOL material without impact on visual acuity. Other eye diseases were within the normal range of the patients' age. Conclusion: Seven years after implantation and refractive adjustment, eyes with an LAL had stable refraction, good visual acuity, and no IOL-associated pathologies. The findings suggest that LAL technology is a safe and efficient method to achieve good visual results without long-term complications. Abstract : The light-adjustable intraocular lens (IOL) provides stable refraction, good visual acuity, and no IOL-associated pathologies 7 years after surgery and lock-in.
