Abstract
This pilot study was aimed to look for morphological differences between the two eyes of
patients with asymmetrical cataract.
Cataract patients visiting the eye clinic USM had their eyes measured (biometry) and
cataracts graded with modified cataract grading system of whom fifty-one patients (102
eyes) were found to have the defined significant asymmetrical cataracts between the fellow
eyes. The two eyes of these patients were grouped into severe (1) and less severe (2)
cataract groups. The ocular biometries were analyzed.
More patients were found to have longer axial length and thinner lens morphology on their
more cataractous eyes. Means of biometric readings of the two groups were analyzed using
independent t test. The lenses of the group 2 were found to be significantly thicker than
that of group 1. (t=2.568, P=0.012) The mean axial length, anterior chamber depth and the
keratometric reading between the two groups were not significantly different statistically
In conclusion, axial length, keratometric reading, anterior chamber depth and lens
thickness; their role for the occurrence of the cataract asymmetry is uncertain, a more
detailed study taking more obvious cataract asymmetry as the criteria; longer study period
involving more blinded observers and including other ocular feature like the volume of the
eye is recommended for the future study on cataract asymmetry.
