Summary

Multifocal IOLs that maintain distance focus and improve near vision have been developed to reduce spectacle dependence.Multifocal IOLs improve patient performance of near-vision tasks, such as reading crafts, hobbies, and social activities to a greater extent than do monofocal IOLs. However, halos and reduced contrast sensitivity have been associated with multifocal IOLs and are common reasons for patient's dissatisfaction.Trifocal technology has been developed to create intermediate focus to overcome these difficulties. Continuous reports of the visual outcomes of the FineVision trifocal IOLs are encouraging.

Detailed description

Monofocal IOLs, which provide effective distance vision, currently account for the majority of IOLs implantations. Patients who have undergone cataract surgery with implantation of monofocal IOL may require spectacles to perform near-distance (e.g., reading) or intermediate-distance (e.g., using a computer) tasks depending on their visual demandsMultifocal IOLs that maintain distance focus and improve near vision have been developed to reduce spectacle dependence.Multifocal IOLs improve patient performance of near-vision tasks, such as reading crafts, hobbies, and social activities to a greater extent than do monofocal IOLs. However, halos and reduced contrast sensitivity have been associated with multifocal IOLs and are common reasons for patient's dissatisfaction.Trifocal technology has been developed to create intermediate focus to overcome these difficulties.
