Schirmer Tear Test Strips

Product Description

Schirmer Tear Test Strips are used for diagnosing reduction of the tear secretion caused by any related ophthalmic diseases. Made of filter paper. This newly designed product has a calibrated scale printed on the strip, on which a color line made of fluorescent dye will co-migrate with the tear flow. An easier and more precise reading will be provided. Strips can be kept for result comparison before- and after- treatment.

Direction:
Take one strip out of the pouch by forcep and make a crease at the tip of the strip. Put the creased end inside of patients lower lid with the other end out of the lid. Patient has to keep his or her eyes closed gently for 5 minutes, which give a proper time for the strip moistened by the tear flows. Then the strip can be taken off, but another *-minute waiting time is required before the length of the moistened area can be read. It is normal if the length is between  *0 mm  and  *5 mm . For an elderly patient who has relatively less tear secretion, if the length of the moistened area is less than  *0 mm , his or her tear secretion may be normal as well.

Attention:
1. Sterilized by oxirane. Single use only. Do not use if pouch is broken.
2, Patient should close eyes gently. Avoid touching cornea. 

Size:2 strips / pouch, *0 pouches/box.
