Presbyopia is an eye condition in which your eye slowly loses the ability to focus quickly on objects that are close. This condition is part of the aging process. It occurs when the natural lens of the eye becomes harder and less elastic. This loss of flexibility reduces the eye’s ability to switch from seeing objects at a distance to seeing objects that are close up. Over time, while distance vision may still be very good, near vision gets progressively worse.
The final frontier for refractive surgery is the surgical correction of presbyopia. One strategy that is useful is surgical monovision, which is a strategy to correct presbyopia by correcting one eye for distance vision and one eye for reading vision. Now, there are options for surgical correction of presbyoipia at the time of cataract surgery. These include monovision with single vision intraocular lenses (IOLs) and now the option of aiming for both near and distance vision in both eyes with multifocal or accommodating IOLs.
