Orlando, Fla.-based LensAR has raised $2.3 million so far among 3 unnamed investors, hoping to hit $19.8 million in equity funding, according to documents filed with the SEC.

The fundraising round, launched at the start of the month, isn’t independent of any other business transaction, the company noted.

The cataract surgery systems maker has had a good year, having in April won FDA 510(k) clearance to market its laser system for both corneal and arcuate incisions during cataract surgery and for anterior capsulotomy – an incision to open the capsule surrounding the eye’s lens.

The LensAR Laser System is currently available for sale to cataract surgeons in the U.S., Europe and several other countries around the world.
