The somewhat entertaining consignment of the keratometer to 'Room 101' at the British Contact Lens Association (BCLA) conference in June 2015, by the esteemed Professor Lyndon Jones, recognised the limitations of this instrument.
(28) found the mean tear thinning time (TTT) values to be ~16 s for normal and 7 s for dry eyes using Bausch and Lomb keratometer, whereas Craig et al.
[USPRwire, Thu Sep 27 2018] Auto keratometer, or an autorefractor keratometer, is a device used for the measurement of cornea anterior surface curvature across a fixed chord length.
[ClickPress, Wed Sep 26 2018] Auto keratometer, or an autorefractor keratometer, is a device used for the measurement of cornea anterior surface curvature across a fixed chord length.
In both cases and controls, eye parameters such as lens thickness (LT), anterior chamber depth (ACD), and axial length (AL) were recorded using A scan ultrasound, IOP was recorded with Schiotz Tonometer and corneal curvature (CC) (vertical and horizontal) with Keratometer. Data were analyzed by students t-test, using SPSS software version 16.
Determination of corneal power with a keratometer (or only the data from the anterior surface of the cornea obtained with a corneal topographer or tomographer) uses the keratometric index, which allows obtaining that approximate value without measuring the curvature of the posterior surface of the cornea, which constitutes an approach with results quite close to reality in virgin corneas.
In cases where measurements could not be made using these devices, A-scan ultrasonography was used and keratometry values were calculated using an autorefractor keratometer. Age-appropriate keratometry values were used for patients for whom keratometry could not be performed.
Keratometry was done on Haag-Strait manual keratometer and A-scan was done by applanation contact method on SonoMed machine.
Corneal astigmatism was measured by Bausch and Lomb manual keratometer preoperatively and at the 1st, 4th and 6-8th weeks post-operatively.
By the introduction of operating microscope auto reflector, Slit lamp biometry keratometer phacoemulsion machines, good antibiotics, better clinical Laboratory services and a bit improved eye surgeon skill and his assistant services things are changed.
A Bausch and Lomb keratometer was used for taking the keratometry readings.
