Review of Mix-and-Match Approach and Binocular Intraocular Lens Systems

Area of Science:

• Ophthalmology
• Biomedical Engineering

Background:

• The mix-and-match approach involves implanting two different intraocular lens (IOL) models in each eye.
• Binocular IOL systems utilize a fixed combination of two complementary lenses.

Purpose of the Study:

• To explore the potential of mix-and-match and binocular IOL systems in achieving desired binocular visual outcomes.
• To highlight the expanded options for patient-specific IOL selection.

Main Methods:

• Review of literature describing various combinations of IOLs in the mix-and-match approach.
• Analysis of initial data on binocular IOL systems and their depth of focus compared to trifocal IOLs.

Main Results:

• Mix-and-match combinations include bifocal, extended-depth-of-focus (EDOF), trifocal, and enhanced monofocal IOLs.
• Binocular IOL systems show potential for depth of focus comparable to bilateral trifocal IOL implantation.
• Outcomes are dependent on the specific IOL combination used.

Conclusions:

• Mix-and-match and binocular IOL systems offer expanded possibilities for tailoring IOL selection to individual patient needs.
• Further comparative studies are required to assess binocular outcomes against conventional approaches.
