Difference between Multifocal and Monofocal lenses

Monofocal lens corrects vision at one distance whereas multifocal lens improves near vision, intermediate vision, and distance vision. Monofocal lenses might require a person to wear glasses after surgery but multifocal lens is said to reduce or prevent the use of glasses after surgery.

Advantages Of Mono-focal Lens

The advantages that a mono-focal lens causes a patient to have if used in cataract surgery are as follows-

• Improved Distance Vision: Monofocal lenses have been proven to correct vision at one focus in a lot of patients very effectively. Doctors and surgeons can determine the accurate focal point for which the treatments need to be performed.
• Budget-friendly: Monofocal IOLs are very affordable and effective compared to multifocal lenses. Multifocal lenses are 10-30 times more costly than monofocal lenses.
• Many people with astigmatism have reportedly achieved better vision with advanced mono-focal lenses. The people having to still wear glasses after surgery have better low-light vision than they would have attained if they chose a multifocal lens.
• Monofocal lenses, once implanted, work very sufficiently for the desired distance without having to provide any maintenance.
• Monofocal lenses reduce the need to wear glasses for distance vision like driving, whereas, a person might still be required to wear glasses for close-up tasks such as reading a book.

Disadvantages Of A Monofocal Lens

• Monofocal lenses provide clarity at either near vision intermediate vision or distance vision. These lenses have a fixed range of focus, therefore, people getting an implant for distance vision might still require reading glasses and people having an implant for near vision will need glasses for distance vision.
• Despite getting an implant, the patient will have to have glasses for a focal point that the lenses do not cover. This increases the patient’s dependency on glasses for other focal points.
• Since the mono-focal lens does not adjust according to different distances, some patients may experience discomfort adapting to constant changes in wearing or removing glasses.

Advantages Of Multifocal Lens

Implantation of the multifocal lens can benefit you in several ways-

• Improves overall vision- Multifocal lens improves all three- near, intermediate, and distance vision simultaneously. Multifocal lenses work best when implanted in both eyes as these lenses can adjust according to different ranges of vision.
• Patients have the feasibility to work on multiple tasks without having to change glasses in between. People having active lifestyles and busy schedules find this option very convenient.
• The multifocal lens helps in reducing the usage of glasses or corrective lenses as it can adjust through different vision altogether.

Disadvantages Of Multifocal Lens

The multifocal lens has multiple functions and can provide better vision at all ranges, however, it also has some disadvantages:

• A few patients have reported experiencing halo or glare looking at lights in the nighttime with a multifocal lens.
• Multifocal IOLs have also caused some patients to suffer contrast sensitivity when reading under a dim light.
• Multifocal lenses are far more expensive respective to their complex designs than monofocal lenses.
