Intraocular Pressure Measurement
Applanation measures pressure by flattening a defined corneal area and recording the force required, with the prism brought into contact under slit lamp illumination. The instrument produces a reading; how that reading is interpreted and what follows from it rests with the clinician performing the examination. The instrument measures; the clinician decides what follows. Illumination and magnification come from the lamp itself. Force required to flatten that area gives the reading.
Services Valuing a Stated Tolerance
A documented tolerance within 0.5 mmHg gives a service something concrete to weigh, which is more than many instruments in this category publish. Whether that figure has been independently verified is a separate question, and Medigear.uk can supply whatever validation the manufacturer holds. Independent verification is a separate matter entirely. Medigear.uk can supply whatever validation is held. A stated number beats an adjectival claim every time.
Departments With Existing Slit Lamps
Because the instrument mounts rather than standing alone, it suits departments already equipped with a slit lamp. Compatibility between the tonometer fitting and the particular lamp is the practical question to settle, and no mounting standard appears on this documentation. Fittings are not universal between manufacturers. No mounting standard appears on this documentation. Compatibility is the practical question to settle first.
Services Reviewing Infection Control
Any instrument contacting the cornea of successive patients falls within a department's decontamination policy. Prism material, whether it is reused and how it is disinfected all need answering before the instrument enters service rather than being discovered afterwards. Successive patients make the question a live one. Policy questions belong at the outset rather than later. Prism handling sits within that policy directly.
