Advantages of using Multifocal Glasses – Guide
Multifocal lens implants give patients the ability to see at a distance, as well as read up close and sometimes at medium distance without glasses, using the computer without glasses. Patients need to understand the potential visual effects they must accept as a potential side effect of multifocal lenses.
In particular, they are halos or reflections around light sources. For example, when patients go out at night or as passengers in a car, lights in other cars may sometimes have a halo around them or may be bright and streaked. This occurs in a minority of patients and is mild to moderate in severity and is not particularly intrusive. This would not prevent patients from driving at night or opting for another operation.
Multifocal IOLs are a type of prosthetic lens used in cataract surgery. Some patients choose to have this lens put on before they develop a cataract, a procedure known as refractive lens replacement. During cataract or lens replacement surgery, the patient’s natural lenses are replaced with multifocal IOLs. These new lenses improve near, medium and distance vision.
Concentric rings are etched into the surface of the multifocal lens, making it possible to focus images at different distances onto the retina. Ultimately, multifocal IOLs provide restored visual function and reduce or eliminate the need for corrective eyewear.
Benefits of using multifocal glasses
Multifocal IOLs provide a greater range of focusing power
Multifocal IOLs offer the obvious advantage of being able to focus at multiple ranges. It is still possible to achieve multiple focus ranges with monofocal lenses, but this requires a method known as monovision. With monovision, one eye is corrected for nearsightedness or distance, while the other is left in its normal focusing power. This allows you to switch between dominant eyes and have some degree of focusing power. However, some people may find this method disorienting and difficult to get used to compared to multifocal IOLs, with no noticeable drop in vision quality.
Multifocal IOLs Can Completely Eliminate the Need for Eyeglasses
Imagine being able to remove your cataracts and having to wear reading glasses all at once! According to studies, about 70% of patients end up up not needing glasses after surgery! This compares with about 25% of patients who were without glasses after receiving monovision treatment. For many patients, multifocal IOLs are worth it just because they don’t have glasses!
Multifocal IOLs are better at seeing up Close
An accommodative IOL acts as your eye’s natural lens. It physically moves in your eye, “accommodating” to changes in visual depth. Accommodating IOLs also gives patients a wide range of focusing power, but struggle to see up close unlike multifocal IOLs. If your lifestyle includes significant time reading, using the computer, or anything else that requires you to see the fine print, consider multifocal IOLs!
