Profile
Develops precision ophthalmic surgical tools for eye procedures like vitrectomies.
MicroSurgical Technology (MST) is a Redmond, Washington-based developer of ophthalmic surgical instruments, founded in 1976 with a focus on addressing routine surgical challenges. The company specializes in precision tools for vitreoretinal and cataract surgery, with its flagship Vista 1-Step vitrectomy probe gaining traction in 2025. MST operates in the $13.3 billion global surgical robotics market, which is growing at 21% CAGR as of 2020 projections.
In April 2025, MST presented clinical data at the ASCRS conference showing 86% symptom resolution in pseudophakic patients using its 27-gauge Vista 1-Step probe. The device connects to major phaco/posterior units and cuts at 11,000 cycles per minute. While independent financials aren't disclosed, MST was acquired by NIIT Learning Systems in 2026 as part of the latter's European expansion strategy, suggesting MST's valuation was substantial enough to warrant inclusion in a publicly traded company's M&A activity.
