However, it can be a problem for patients that are not yet presbyopic (or are in the early stages of presbyopia) undergoing refractive lens exchange for the sake of correcting refractive errors. Monovision, in which one eye is made emmetropic and the other myopic, can partially compensate for the loss of accommodation and enable clear vision at multiple distances. More versatile types of lenses (multifocal and accommodating IOLs) were introduced in 2003 in the United States, with the approval by the Food and Drug Administration. These come at an additional cost to the recipient beyond what Medicare will pay and each has advantages and disadvantages. Multifocal
Multifocal IOLs attempt to provide simultaneous viewing of distance vision and near vision. Trifocal IOLs can provide intermediate vision. Many multifocal IOL designs attempt to achieve this simultaneous viewing focus using a concentric ring design, which alternates distance and near focal points. However, many concentric ring multifocal lenses used today are prone to glare and mildly compromised focus at all ranges of vision. People who have a multifocal IOL after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. However, people receiving multifocal lenses may experience more visual problems than with monofocal lenses. The most common adverse visual effects from multifocal IOLs include glare, halos (rings around lights), and a loss of contrast sensitivity in low-light conditions. Adjustable Lens
An adjustable IOL is unlike any other lens as its prescription power can be adjusted after surgery once all healing is complete.
Lisinopril/hydrochlorothiazide, sold under the brand name Zestoretic among others, is a fixed-dose combination medication used for the treatment of high blood pressure.

It is available as a generic medication. In 2020, it was the 50th most commonly prescribed medication in the United States, with more than 13 million prescriptions. References
