Radius of corneal curvature, anterior chamber depth, lens thickness and axial length: Comparison between normal and cataractous eye in monocular cataract patients.

ABSTRACT

The authors studied monocular cataract patients in the In-patient section, Department of Ophthalmology, Siriraj Hospital, from 1 st April 1987 to 30 th September 1987 or 6 months, to compare normal eyes and cataractous eyes. A total of 70 monocular cataract patients were studied, 24 female (34.29%); 46 male (65.71%). Cataracts occurred in the eight eye of 48 patients (68.57%), in the left eye of 22 patients (31.43%). Ages ranged from 28/81 years, average 58.06. The mean radius of corneal curvature in vertical meridian of normal eye = 7.76 + 0.29 mm. or 43.50 + 1.62 diopters, of cataractous eye = 7.76 + 0.33 mm. or 43.50 + 1.83 diopters. The mean radius of corneal curvature in horizontal meridian of normal eyes = 7.742 + 0.28 mm. or 43.60 + 1.53 diopters, of cataractous eyes = 7.788 + 0.33 mm. or 43.34 + 1.81 diopters. The mean anterior chamber depth of normal eyes = 2.74 + 0.41 mm., of cataractous eyes = 2.80 + 0.39 mm. The mean lens thickness of normal eyes = 4.30 + 0.46 mm., of cataractous eyes = 3.82 + 0.64 mm. The mean axial length of normal eyes = 23.02 + 0.99 mm., of the cataractous eyes = 23.20 + 1.06 mm. The mean lens thickness of the cataractous eyes was statistically sightfcantly less than the mean lens thickness of normal eyes, (p < 0.001).
