[Clinical and histopathologic analyses of after cataract in rabbit eyes having undergone three different cataract
1Department of Ophthalmology, Affiliated Tongren Hospital, The Capital Medical University, Beijing 100730, China.
Objective:
To discuss the surgical method which can efficiently prevent the occurrence of after cataract.
Methods:
Eighteen experimental rabbits were randomly divided into 3 groups. Group A was treated with phacoemulsification, group B with phacoemulsification combined with posterior continuous curvilinear capsulorhexis (PCCC) and Group C phacoemulsification combined with PCCC and anterior vitrectomy. Post-operatively, all the surgical eyes were checked with slit lamp microscope and ophthalmoscope. At the post-operative 3 months, histopathologic examinations were performed.
Results:
There were no post-operative complications, such as retinal detachment, cystoid macular edema, etc. There were Elschnig's pearls and fibers in the peripheral area of the posterior capsule, and the amount was about the same in the 3 groups. There were Elschnig's pearls and fibers at the central area in group A. The fibrous membrane grew from the edge of the PCCC in group B. But in group C, the central area of the posterior capsule was clear, and there was no obvious pathological changes.
Conclusion:
Phacoemulsification combined with PCCC and anterior vitrectomy is a safe cataract surgical method which can effectively prevent the formation of after cataract.
