Accommodation Amplitude and Visual Acuity of the Accommodative Intraocular Lens, the AkkoLens Lumina
Comparison of accommodation amplitude and visual acuity of the Akkolens Lumina with a monofocal intraocular lens.
This clinical study included 16 eyes of 16 different patients, with all eyes suffering from cataract. Eyes were divided in two groups; group 1, with 11 eyes of 11 patients to be implanted with the Akkolens Lumina, and group 2, with 5 eyes of 5 patients, to be implanted with the Acrysof SN60AT.
In this prospective, non-randomized study visual acuity, residual refractive error and defocus responses were measured.
Results and Conclusion
Corrected distance visual acuity was not statistically significantly different between the two groups (p=0.72), meaning that the Lumina and the Acrysof performed the same. However, the defocus response of group 1 was significantly better (p<0.01), with a mean visual acuity of 0.64±0.22 (decimal scale) for a defocus stimulus of -3D (equivalent to a reading distance of 33cm) compared to group 2. The defocus response for a defocus stimulus of 1.5D (equivalent to 66cm) was not significantly different between the groups (p=0.07), but here group 1 showed a mean visual acuity of 0.81 compared to 0.67 for group 2. The defocus curve was significantly better in group 1 (p<0.05). In conclusion, the preliminary results show that the Akkolens Lumina successfully restores visual acuity for far and for near and also provides sufficient accommodation to allow sharp vision up to a reading distance of 33cm.
