Once cataract was diagnosed and surgery was planned, keratometry was done on Haag-Strait manual
keratometer and A-scan was done by applanation contact method on SonoMed machine.
This can be done in a clinical setting by observing the image of a given pattern reflected on to the tear film surface, for example using
keratometer mires or the Keeler TearScope grid pattern (see Figure 2).
Keratometry was done to measure corneal curvature using Bausch and Lomb
keratometer.
Anterior segment clinic is equipped with Photo slit lamp for anterior segment photography and an auto refractor
Keratometer.
Corneal Power and Intra Ocular Pressure were also measured using
keratometer and applanation tonometry, respectively.
Keratometry was performed preoperatively and postoperatively by using Bausch and Lomb
Keratometer.
Comparison of corneal curvature and anterior chamber depth measurements using the manual
keratometer, Lenstar LS 900 and the Pentacam.
Keywords: Auto refractor,
Keratometer, WTR, ATR, Oblique astigmatism, Prevalence.
Corneal curvatures were measured using Bausch and Lomb
keratometer while refraction was performed using Cannon autorefractometer.
Autorefracto
keratometer will be used for refraction testing and for measuring the radius of curvature of cornea.
Discussion: LenStar has provided comparable and well-correlated keratometry measurements in comparison with automated
keratometer and corneal topography.
Tenders are invited for Supply of Auto Refractometer with
Keratometer
