Fluorescent viscoelastic enhancement.
By inserting an Erreger 485 exciter filter into the operating microscope, translucent yellow Healon (sodium hyaluronate) transforms into a brilliant opaque green viscoelastic. We have developed this technique and termed it "fluorescent viscoelastic enhancement." Using the technique, we demonstrated that the time required to remove Healon from the anterior chamber after intraocular lens insertion varies. Healon is usually aspirated quickly, in less than 17 seconds. Otherwise it traps behind the intraocular lens and requires more time for irrigation/aspiration (I/A) and manipulation of the I/A tip. Fluorescent viscoelastic enhancement minimized I/A time, reducing excess turbulence and manipulation in the anterior chamber, and thus may reduce corneal endothelial cell loss. This study also demonstrated that fluorescent viscoelastic enhancement prevented postoperative intraocular pressure rise, compared to the conventional removal of clear Healon. Fluorescent viscoelastic enhancement assures the surgeon that a large amount of Healon is not left behind.
