The mean addition required for near vision (reading at 40 cm) was 1.87 D after 1 month, 1.66 D after 3 months and 1.5 D after 6 months.
However, contradictory opinions exist about whether the lens thickness continues to increase after 50 years of age.
The London Eye Hospital is now able to offer you the next generation of multifocal intraocular lenses (IOL’s) – the trifocal.
This implant gives patients a better chance to enjoy clear vision at all distances with maintained contrast sensitivity and lower visual disturbance.
CONCLUSIONS: The Synchrony® dual-optic lens is a promising option for the treatment of presbyopia in patients following cataract surgery, due to its special design.
However, new designs are required to improve this capability.
