Zeiss Applanation Tonometer

This Zeiss Applanation Tonometer is a used slit-lamp mounted instrument that measures intraocular pressure by gently flattening a small area of the cornea, following the well established Goldmann applanation principle. It remains a trusted reference method in ophthalmology for accurate IOP assessment, particularly in glaucoma diagnosis and management where precise pressure readings guide treatment decisions. The unit has been inspected for smooth mechanical operation and is offered in solid working condition with expected cosmetic wear from clinical use. Built to attach directly to a compatible slit lamp, this tonometer relies on a calibrated measuring prism and manual dial to determine pressure, giving clinicians a highly regarded, repeatable method that many consider the clinical gold standard. Its simple mechanical design means it requires little more than routine cleaning and periodic calibration checks to remain reliable in daily use. This durability has kept applanation tonometry a staple in eye care practices for decades. This used Zeiss Applanation Tonometer is well suited for ophthalmology and optometry practices that want a dependable, clinically validated tool for confirming intraocular pressure readings, especially when following up on results obtained from non-contact screening devices. It is ready to be mounted and used with an appropriate slit lamp setup.
