There is no apparent connection between van Leeuwenhoek who developed his simple (single lens) microscope system and the work of Zacharias Janssen is associated with the compound (two lens) microscope invented in 1590.
Van Leeuwenhoek was unable to use the compound microscope because magnification was too low. The microscopes built by van Leeuwenhoek (around 1670) had ten times the magnification of the compound microscopes of the day.
One could say that Janssen helped van Leeuwenhoek succeed by getting everyone else to use the inferior microscope.

The first microscope to be developed was the optical microscope. An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Zacharias Janssen. Van Leeuwenhoek improved a microscope and first described cells seen in cork tissue. He called them cells as they looked like little rooms, similar to ones that monks lived in.

Zacharias Janssen was a Dutch spectacle-maker of Middelburg. Hans Janssen and his son Zacharias Janssen, Dutch spectacle-makers, are frequently cited as having invented the first compound microscope in 1590, but there is a good deal of dispute. They may not have. Zacharias Janssen was the one who actually made the claim, and in the middle of the 1600's. A number of historians, however, agree that it is imporbable that 1590 is correct. There is a good deal of evidence that Zacharias Janssen was born somewhere around 1590.
