Results: All the eyes' visual acuity recovered to the best level prior to posterior capsular(opacity) occurrence,corrected visual acuity 0.1-0.4 in 58 eyes,0.5-0.8 in 54 eyes,1.0 in 8 eyes.90 percent were succeed in one laser shot,no intraocular lenses damage was found in slit lamp microscope examination.Conclusion: laser can resect the posterior capsular opacity effectively,improve the visual function of the affected eye.Assisted with amblyopia treatment, laser capsulotomy play an important role in visual function reconstruction in these patients.
