AcuityMaster vs M&S Smart System 20/20
M&S Technologies is one of the most widely used digital chart platforms in US ophthalmology. Here is how AcuityMaster Cloud stacks up on the features and costs that matter most.
Quick verdict: AcuityMaster Cloud runs on the Mac or Windows computers you already have at $249/seat/year, with no hardware bundle — while the M&S Smart System 20/20 is a Windows-only, hardware-based system typically priced around $1,500–$2,500 per lane. A 5-lane office pays roughly $745/year with AcuityMaster.

The bottom line
M&S Smart System 20/20 is a comprehensive, well-established platform used across US ophthalmology — but it is Windows-only, requires local installation, and carries a significantly higher price tag, particularly for multi-lane practices. AcuityMaster Cloud delivers comparable clinical functionality at a fraction of the 5-year cost, with the added advantage of Mac and iPad compatibility and zero installation overhead.
