[Application of corepraxia in the implantation of intraocular lens].

PURPOSE: In the cases of aphakia or cataract which complicated with iridosteresis, corectasis and pupil displacement, corepraxia was performed when implanting intraocular lens (IOL) in order to recover the normal shape and position of pupil, improve postoperative visual acuity and prevent monodiplopia and glare.

METHODS

In the cases which have iridosteresis at the direction of 9-3 oclock or updrawn pupil, iris suture was performed at the incision directly(open method); while those at the direction of 3-9 o'clock, operation was performed outside the anterior chamber (close method).

RESULTS

In 22 cases, the percentage which having visual acuity better than 0.5 is 65%, having nearly round shape pupil 67%, having pupil diameter less than 3 mm 73%, having normal pupil position 67%.

CONCLUSION

All kinds of deformed pupil can be recovered to their normal shape, size and position by performing corepraxia while IOL was implanted. The prolene has light reaction and better effect in iris suture.
