YZ38 Keratometer, Precision:0.02mm, 0.25 dptr, Corneal: 5.5 ~ 11mm

YZ38 Keratometer – Precision Corneal Measurement for Eye Care Professionals

Product Code: YZ38

Product Overview

The YZ38 Keratometer is a high-precision ophthalmic instrument designed for accurate measurement of corneal diopter, corneal astigmatism axis, and astigmatism diopter. It also supports measurement of intraocular lens (IOL) diopter when used in conjunction with A-scan ultrasound. Whether you're fitting contact lenses, planning refractive surgery, or conducting routine eye exams, the YZ38 delivers reliable, repeatable results you can trust.

Key Applications

• Corneal diopter measurement – Accurately measures the refractive power of the corneal surface
• Corneal astigmatism assessment – Determines both the axis and diopter of corneal astigmatism
• IOL diopter calculation – Assists in calculating implant lens power when combined with A-scan ultrasound
• Contact lens fitting – Provides essential baseline data for precise lens selection
• Pre- and post-operative evaluation – Ideal for refractive surgery planning and follow-up
