The Keratometer KMS-6 is a high-precision manual ophthalmic keratometer designed to measure the curvature of the anterior corneal surface accurately. It is widely used in optometry clinics, ophthalmology practices, hospitals, and optical centers for determining corneal astigmatism, fitting contact lenses, and conducting pre-operative assessments.

Key Features

✔ Accurate Manual Keratometry

• Measures both principal meridians (R1 & R2)

• Provides dioptric power and axis of corneal astigmatism

• Highly reliable readings for contact lens fitting

✔ Precision Optical System

• Uses high-quality, calibrated optics

• Clear mires allow for accurate alignment and focusing

• Minimal distortion for consistent measurements

✔ Smooth Mechanical Movement

• Fine adjustment knobs for vertical and horizontal alignment

• Stable base ensures consistent readings

• Mechanical durability suitable for daily clinical use

✔ Adjustable Chinrest & Head Support

• Ensures stable patient positioning

• Reduces movement for better repeatability

✔ Easy-to-Read Scale

• Large, clear diopter and millimeter readings

• Enables quick interpretation by clinicians and students

✔ Durable, Reliable Construction

• Metal frame built for long-term use

• Ideal for high-volume eye clinics and teaching institutions

Benefits

• Provides accurate corneal curvature measurements essential for:

  • Contact lens fitting (soft & RGP)

  • Cataract IOL calculations

  • Refractive surgery evaluations

  • Detecting keratoconus and corneal irregularities

• No electronics → low maintenance and long service life

• Perfect backup to digital keratometers and autorefractors

• Ideal for training environments due to its manual precision
