The radius of curvature of the anterior corneal surface and its refractive power and astigmatism were measured with the Javal Schi(?)s Keratometer in two groups totalling 62 eyes, In the groups of 31 eyes before retinal detachment surgery and 31 eyes of normal control, the radius of curvature and refractive power were not significantly different between the two groups (P>0.05), However, the astigmatism was significantly different (P<0.05). In 31 eyes after retinal detachment surgery, the astigmatism varied...

The radius of curvature of the anterior corneal surface and its refractive power and astigmatism were measured with the Javal Schi(?)s Keratometer in two groups totalling 62 eyes, In the groups of 31 eyes before retinal detachment surgery and 31 eyes of normal control, the radius of curvature and refractive power were not significantly different between the two groups (P>0.05), However, the astigmatism was significantly different (P<0.05). In 31 eyes after retinal detachment surgery, the astigmatism varied significantly following segmental scleral bucking, a high degree of astigmatism may be produced (P<0.01). Encircling procedure is of no great clinical importance (P>0.05).

We studied on the methodology of the self-characteristically designed computerassisted corneal topographic analysis system first in our country. It might analyse the images Which were caught from the anterior surface of the cornea directly and calculate the radial curvature and refraction of the points on the anterior corneal surface. The precision of this machine is high and error is minimal when checked out by two different standard steel balls. It could demonstrate the refraction and the radial curvature of the horizontal meridian of the anterior corneal surface accurately and sensatively when tested clinically in normal person, myopes and patients who were performed with radial keratotomy or cataract extraction.
