Presbyopia is a common condition which begins to affect people over 40 years of age. Beginning around age 40, the natural lens inside the eye begins to harden and become less flexible. This reduces the eye’s ability to switch focus from near, to far and back again. The earliest sign of presbyopia is difficulty reading or having to push reading material further away.
Traditional intraocular lens solutions for treating presbyopia include multifocals, which work on the principle of simultaneous vision by splitting light into two distinct foci, near and distance. Accommodating IOLs are another version, which rely on the eye’s ability to assist in focus. Multifocal intraocular lenses are more prone to halos around headlights at night. Although accommodating lenses permit intermediate vision, there are limitations to close vision.
Traditionally with these technologies, the correction of presbyopia is commonly thought of in terms of the distinct distance for which functional vision is provided.
