With the 1CU, the shift-induced accommodative effect was calculated to be less than 0.5 D in most cases, while 1 D was achieved in a single case only.Ranges and standard deviations were very large in relation to the mean values.Background Accommodation is the ability of the eye to focus on both distant and near objects.
This is a problem for most people in their 40s or 50s.
Standard IOLs, known as monofocal IOLs, allow only distant objects to be focused and seen clearly. This problem after showed that participants who received accommodative IOLs had improvements in near vision at six months and at 12 months after surgery compared to those who received monofocal IOLs.
However, such improvements were small and reduced with time.
Better DCNVA was seen in the accommodative lens group at 12 to 18 months in the three trials that reported this time point but considerable 0.05 to 0.19; 40 people, binocular) log MAR improvement (low quality evidence).
The relative effect of the lenses on corrected distant visual acuity (CDVA) was less certain.
