For optometrists, ophthalmologists, and clinic managers, keeping this machine running accurately is essential for patient safety and clinic flow.<\/span><\/p>\n<p><span style=\"font-size: 14pt;\">At Shanghai Link, we understand that the reliability of your Ophthalmic Equipment directly impacts patient outcomes. With over 15 years of manufacturing expertise in Shanghai, we provide high-precision Air Puff Tonometer designed to meet the rigorous demands of global clinics.<\/span><\/p>\n<h2><span style=\"font-size: 18pt;\">What is an Air Puff Tonometer?<\/span><\/h2>\n<p><span style=\"font-size: 14pt;\">An air puff tonometer is a type of <span style=\"color: #800000;\"><a style=\"color: #800000;\" href=\"https:\/\/linkeyegroup.com\/pt\/categoria-de-produto\/tonometro\/\"><strong>non-contact tonometer<\/strong> <\/a><\/span>that estimates IOP by emitting a gentle, calibrated burst of air onto the cornea. The device measures the time it takes for the cornea to flatten (applanate) under this air pulse. Since higher IOP resists flattening longer, the machine calculates pressure based on the air-pulse duration and force.It quickly screens for glaucoma without touching the eye, making it non-invasive and removing the need for numbing drops.<\/span><\/p>\n<p><span style=\"font-size: 14pt;\">Unlike Goldmann applanation tonometry\u2014which requires topical anesthetic and direct contact\u2014the air puff method is:<\/span><\/p>\n<ul>\n<li><span style=\"font-size: 14pt;\">Painless and non-invasive<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Quick (under 5 seconds per eye)<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Ideal for initial glaucoma screening<\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 14pt;\">While slightly less precise than contact methods in extreme corneal thickness cases, modern NCTs offer excellent repeatability for routine use.<\/span><\/p>\n<h2><span style=\"font-size: 18pt;\">How Does an Air Puff Tonometer Work?<\/span><\/h2>\n<p><span style=\"font-size: 14pt;\">The air puff tonometer measures the internal pressure of the eye without ever physically touching the ocular surface. This is a major advantage for infection control and patient comfort (as it doesn&#8217;t require numbing drops).<\/span><\/p>\n<h3><span style=\"font-size: 14pt;\">Technology Works:<\/span><\/h3>\n<ul>\n<li><span style=\"font-size: 14pt;\">Alignment: The patient focuses on a target light within the machine.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Applanation: The device releases a gentle puff of air.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Measurement: An advanced optical sensor measures the time or force required to flatten a specific area of the cornea.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Calculation: The machine converts this data into a numerical value measured in millimeters of mercury (mmHg).<\/span><\/li>\n<\/ul>\n<h3><strong><span style=\"font-size: 14pt;\">Comparison of Tonometry Methods:<\/span><\/strong><\/h3>\n<table class=\"NRefec\" data-animation-nesting=\"\"
