[A clinical study on clamp technique of intraocular lens on anterior capsule in cases with big rupture of posterior capsule of lens].

Objective: To investigate the long-term results of the clamp technique of the posterior chamber intraocular lens (IOL) on the anterior capsule of lens in cases with big rupture of posterior capsule of lens.
Methods: The clamp technique of the posterior chamber IOL on the anterior capsule of lens were performed on 48 eyes of 48 cases with big rupture of the posterior capsule of lens following extracapsular cataract extraction for senile, traumatic, complicated and diabetic cataract. After 3-60 months follow-up, the vision acuity, position of IOL, capsular opacity and post-operative complications were investigated.
Results: The visual acuity of 39 eyes (81.3%) was >/= 0.5. The position of all IOL was in the optical center. The complications, such as after-cataract, retinal detachment, secondary glaucoma and persistent uveitis were not found.
Conclusion: The clamp technique of the posterior chamber IOL on the anterior capsule of lens is convenient, safe and effectual in cases with big rupture of posterior capsule of lens.
