The Capsular Transplantation in Experimentally Induced Capsule Rupture of Porcine Lens

PURPOSE: We assessed the effect of transplantation of capsule on the change of gross and fine structures of the experimentally induced capsular rupture of porcine lens. METHODS: A rupture of 1.0, 3.0 and 5.0 mm in diameter was made on the anterior capsule of the lens and the anterior capsule was transplanted using lyophilized fibrin adhesive(Greenplast(R)) to cover the rupture. RESULTS: Gross and transmission electron microscopic examinations revealed at day 1, 3 and 7 that the progression of lens opacification was delayed and the stability of microscopic fine structure was less disturbed in the lenses with a rupture of 3.0 mm or less or receiving capsule transplantation less than 4 days after capsule rupture. In the lenses with a rupture of 5 mm or larger or receiving transplantation more than 3 days after capsule rupture, there were no significant differences in gross and microscopic findings between transplantation and control groups CONCLUSION: We applied transplantation concept on the lens. Further studies are needed for transplantation of lens capsule.

Analysis of after Cataract using Scheimpflug Camera

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.
