Analysis of after Cataract using Scheimpflug Camera

ABSTRACT

The posterior capsular opacity is the most common complication occurring after extracapsular cataract extraction with posterior chamber intraocular lens implantation. For the purpose of the object analysis of the posterior capsular opacity, 127 eyes with the posterior capsular opacities were observed at 2 years after operation using the retroillumination and slit beam of Scheimpflug camera. In this study, the patients were undergone extracapsular cataract extraction with posterior chamber intraocular lens implantation at Inha university hospital from January 1997 to December 1997. Of 127 eyes, 89 eyes were free of diabetes mellitus, 38 eyes not. 89 eyes, free of diabetes mellitus, were 24 eyes whose posterior capsular thickness was thinner than 0.06 mm, 40 eyes from 0.06 mm to 0.12 mm, 17 eyes from 0.12 mm to 0.18 mm, and 8 eyes above 0.18 mm.Visual acuity of four groups had statistical difference with one another.There was significant correlation between the mean visual acuity and the thickness of center of the posterior capsule statistically.There was significant correlation between the mean visual acuity and the area of posterior capsular opacity, between the mean visual acuity and the inclusion of visual axis in the opaque area statistically.In conclusion, if we measure the thickness and area of posterior capsular opacity using Scheimpflug camera with regular interval, we will get the knowledge of progression of after cataract.
