The protocol at many optometry schools around the world is to take the central keratometry values and 'add something' to make the lens a certain amount flatter.
5 diopter (D), vertical keratometry value below 47 D, and no keratoconus patterns such as asymmetrical bow-tie pattern, skewed axis, or localized steepening on topography.
Uncorrected and Corrected Distant Visual Acuities (UDVA, CDVA), spherical equivalent (SE), astigmatism, pachymetry at thinnest point (Pachy thin), apex keratometry (Kmax), simulated and steep keratometry (Sim K, steep K) were measured at baseline and at 3, 6 and 12 months post operatively.

Certain biometric readings such as axial length and keratometry are performed before calculating the intraocular lens power for cataract surgery.
The best corrected visual acuity and keratometry was also determined in post-operative cases.
0) = 20 D K--mean keratometry, AL--axial lengths, AC -anterior chamber, L--lens thickness, IOL--artificial intraocular lens power calculation
Nevertheless otoscopy, ophthalmoscopy, electroretinography, keratometry and tracheoscopy have revolutionized the practice allowing better visualization and diagnosis.
Use of biometry and keratometry for determining optimal power for intraocular-lens implants in dogs.
The personal information of all the patients was recorded and proper preoperative assessment, which included visual acuity, slit-lamp examination, tonometry, dilated refraction, fundoscopy, keratometry (opposite normal eye was used in case of corned opacification), IOL power calculation (using SRK-II formula), and B-scan, was carried out.
3, was performed and corneal thickness at the thinnest point, anterior and posterior steep and flat keratometry (K) values were recorded at baseline.
Another possibility is inaccurate preoperative keratometry values in these cases due to irregular corneal surface.
