Findings from a pilot study show that a novel accommodative intraocular lens (AIOL, Lumina, Akkolens) provides a true accommodative response that is maintained for at least 2 years and preserved following Nd:YAG laser capsulotomy.
The study measured objective and subjective accommodative responses in 59 eyes of 43 cataract surgery patients implanted with the Lumina AIOL. The results were compared with those of 2 control groups comprised of 59 eyes of 43 cataract surgery patients implanted with a monofocal IOL (AcrySof SA60AT, Alcon Laboratories) and 25 healthy eyes of patients aged <30 years. The cataract surgery patients ranged in age from 43 to 85 years.
There was inter-individual variability within the Lumina AIOL group in both subjective and objective accommodation gain. However, the overall differences in both the objective and subjective measures of accommodation between the Lumina AIOL and monofocal IOL control groups were statistically significant.
In addition, the data collected suggested that at least two-thirds of the optical power change observed in the Lumina AIOL eyes was explained by real accommodation, whereas pseudoaccommodation contributed less than 30% to the outcome, reported Jorge L. Alió, MD, PhD, professor and chairman of ophthalmology, University Miguel Hernandez de Elche; medical director of the investigational study, VISSUM Instituto Oftalmologico de Alicante, Alicante, Spain.
“The results of this study show that the Lumina AIOL restores visual function after cataract surgery and improves near vision by changing the optical power of the eye,” said Dr. Alió.
