13 Products/Services (Click for related suppliers)

• AC-Powered Lens Measurment Instrument (FDA Code: HLM / 886.1425)

A lens measuring instrument is an AC-powered device intended to measure the power of lenses, prisms, and their centers (e.g., lensometer).

• Battery-Powered Retinoscope (FDA Code: HKM / 886.1780)

A retinoscope is an AC-powered or battery-powered device intended to measure the refraction of the eye by illuminating the retina and noting the direction of movement of the light on the retinal surface and of the refraction by the eye of the emergent rays.

• Crossed Cylinder Lens/Simulatan (FDA Code: HOR / 886.1840)

A simulatan (including crossed cylinder) is a device that is a set of pairs of cylinder lenses that provides various equal plus and minus refractive strengths. The lenses are arranged so that the user can exchange the positions of plus and minus cylinder lenses of equal strengths. The device is intended for subjective refraction (refraction in which the patient judges whether a given object is clearly in focus, as the examiner uses different lenses).

• Maddox Lens (FDA Code: HKR / 886.1400)

A Maddox lens is a device that is a series of red cylinders that change the size, shape, and color of an image. The device is intended to be handheld or placed in a trial frame to evaluate eye muscle dysfunction.

• Manual Non Powered Refractor with Phoropter (FDA Code: HKN / 886.1770)

A manual refractor is a device that is a set of lenses of varous dioptric powers intended to measure the refractive error of the eye.

• Manual Pupillometer (FDA Code: HLH / 886.1700)

A pupillometer is an AC-powered or manual device intended to measure by reflected light the width or diameter of the pupil of the eye.

• Ophthalmic AC-Powered Instrument Stand (FDA Code: HMF / 886.1860)

An ophthalmic instrument stand is an AC-powered or nonpowered device intended to store ophthalmic instruments in a readily accessible position.

• Ophthalmic Prism Bar (FDA Code: HKW / 886.1650)

An ophthalmic bar prism is a device that is a bar composed of fused prisms of gradually increasing strengths intended to measure latent and manifest strabismus (eye muscle deviation) or the power of fusion of a patient's eyes.

• Ophthalmic Projector (FDA Code: HOS / 886.1680)

An ophthalmic projector is an AC-powered device intended to project an image on a screen for vision testing.

• Ophthalmic Refractometer (FDA Code: HKO / 886.1760)

An ophthalmic refractometer is an automatic AC-powered device that consists of a fixation system, a measurement and recording system, and an alignment system intended to measure the refractive power of the eye by measuring light reflexes from the retina.

• Ophthalmic Trial Frame (FDA Code: HPA / 886.1415)

An opthalmic trial lens frame is a mechanical device intended to hold trial lenses for vision testing.

• Ophthalmic Trial Lens Set (FDA Code: HPC / 886.1405)

An ophthalmic trial lens set is a device that is a set of lenses of various dioptric powers intended to be handheld or inserted in a trial frame for vision testing to determine refraction.

• Skiascopic Rack (FDA Code: HMH / 886.1750)

A skiascopic rack is a device that is a rack and a set of attached ophthalmic lenses of various dioptric strengths intended as an aid in refraction.
