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.
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
