To speak with one of our doctors and discuss your options for cataract replacement lenses, please call us today to schedule a consultation.
During your cataract surgery, your natural, cloudy lens is removed and replaced with a new, implantable intraocular lens (IOL).
Before premium lenses, patients were unable to see clearly at both near and far distances without the use of eyeglasses or contact lenses.
Early lens implants were monofocal, meaning that they had only one focal point and could not adjust to varying distances.
A big advantage of multifocal lenses, said Stephen G. D., Houston, is that the Re STOR lens (Alcon, Fort Worth, Texas) has the best near vision of any of the lenses. Slade said, “The disadvantage [of multifocal lenses] is that some patients, not very many, but some have problems with the quality of vision, either glare or halos or they describe waxy vision or things like that.” Paul J. D., clinical instructor of ophthalmology, Jules Stein Eye Institute, University of California at Los Angeles, said of the two multifocals, his preferred lens is the Re STOR Aspheric because it tends to be the most effective at eliminating the need for glasses for distance and near.
“Typically who I use the multifocal Re STOR for patients who are most motivated to eliminate their need for reading glasses and who don’t do a lot of night driving.
Many cataract patients, in addition to suffering from either nearsightedness or farsightedness, also suffer from presbyopia, natural changes to the eyes that occur as we age.
Accommodating IOLs are used in two procedures: refractive lens exchange (RLE) if you do not have cataracts and refractive cataract surgery if you do.
They cannot be used to treat astigmatism, but you can choose to have a separate laser eye surgery procedure to address your astigmatism if you wish. S., only one brand of accommodating IOL is currently available: Crystalens.
When the muscle relaxes, the lens returns to its original position so that you see things in the distance clearly.
Following surgery, you will be able to see at multiple distances. What’s more, it is an outpatient procedure, so you can go home right after your surgery.
