Precision Optical Measurement

With its achromatic lenses and factory calibration, this keratometer offers reliable and precise measurement of corneal curvature. The dual measurement scales provide results in both diopters and millimeters, accommodating a range of clinical requirements.

Engineered for Stability and Accuracy

Constructed from robust metal and designed with a heavy-duty base, this instrument ensures stable operation during critical diagnostic procedures. The corrosion-resistant finish guarantees durability and long-term usability in professional environments.

User-Friendly Features

The adjustable eyepiece, one position focusing mechanism, and pupil distance adjustment make this keratometer comfortable to use. The 360-degree axis rotation facilitates optimal alignment, contributing to more accurate and repeatable measurements.

FAQs of Keratometer:

Q: How does the Keratometer measure the curvature of the cornea?

A: The keratometer uses optical projection and achromatic lenses to measure the corneal curvature accurately by projecting an image onto the corneal surface and analyzing the reflected rays. The readings are provided on analog scales in both diopters and millimeters.

Q: What benefits does the 360-degree axis rotation provide during measurements?

A: The 360-degree axis rotation allows you to align the instrument precisely with the patients eye, ensuring optimal positioning to obtain more accurate and consistent corneal measurements.

Q: When should the Keratometer be used in an ophthalmic practice?

A: This instrument is primarily used during routine eye examinations, contact lens fittings, and prior to refractive surgeries to determine the corneal curvature and assess corneal health.

Q: Where is this keratometer typically utilized?

A: It is commonly used in ophthalmology clinics, eye hospitals, and optometry offices for diagnostics and measurement of corneal curvature in various patient care settings.

Q: What is the process for adjusting pupil distance on this device?

A: The keratometer features an integrated adjustment mechanism for pupil distance. After positioning the patient, you can manually set the distance to align with individual pupil spacing, which helps ensure accurate focus and measurement.

Q: Is the Keratometer portable or rechargeable?

A: No, this is a non-portable, manual instrument without a rechargeable battery. It is designed for stationary use in clinical environments, operating solely through manual input.

Q: What are the advantages of using achromatic lenses in this instrument?

A: Achromatic lenses reduce chromatic aberrations and enhance image clarity, which leads to more precise corneal curvature measurements and improved readability on the analog scale.
