Many people get used to multifocal IOLs right away.Others feel a little imbalanced at first but get used to it within a matter of days or weeks.
If you have astigmatism, leaving it untreated would mean you would need glasses for both distance and near vision after cataract removal.Cataract surgery is a once-in-a-lifetime investment in your eyes that can improve your quality of life for the long term.Advanced lens options can reduce or eliminate the need for glasses after surgery.State-of-the-art multifocal intraocular lenses reduce the need for reading glasses after cataract or lens replacement surgery.These lenses are designed to address the problem of presbyopia, in which people over the age of 40 begin to lose their ability to read or see up close.In the past, when an artificial lens, called an intraocular lens implant or IOL, was placed inside the eye during cataract or lens replacement surgery, it could only focus at a single distance.
These IOLs are called single-focus IOLs and allow an eye to see either far away or close-up but not both.
Advanced intraocular lenses, called multifocal IOLs, provide correction for both near and distance vision.
And both near and far objects can be in focus at the same time.
Your doctor can use laser reshaping of the cornea or an astigmatism-correcting lens implant to treat your astigmatism at the time of cataract removal.
These implants change position within your eye based on your eye muscle effort.
Accommodating lenses can treat astigmatism, but give slightly less near power than multifocal lenses.
