[Anterior segment reconstruction and secondary posterior chamber intraocular lens implantation supported by fibromembrane].

OBJECTIVE

To evaluate the methods and effects of anterior segment reconstruction and secondary posterior chamber intraocular lens (IOL) implantation supported by fibromembrane in pupillary area.

METHODS

Anterior segment was reconstructed in 86 eyes with different anterior segment disorders. Anterior segment reconstruction includes: partial penetrating keratoplasty, loosing front adhesion, suturing detached peripheral iris, loosing rear adhesion, reshaping pupil, perforating fibromembrane in the pupillary area. The IOL was secondarily implanted into the posterior chamber, and the patients were followed up in 3 - 32 months.

RESULTS

The surgery was successful in all patients. The postoperative visual acuities in 71 eyes were >or= 0.5 (82.6%), including >or= 0.9 (39.5%) in 34 eyes and <or= 0.2 in 15 eyes (17.4%). After IOL implantation, the IOL correctly centered was in 68 eyes (79.1%), and deviated in 18 eyes (20.9%). Anterior chamber hemorrhage occurred in 5 eyes, 4 of them were recovered by conservative treatment and the blood membrane in another eye was sucked out through its primary incision. All patients had slight postoperative inflammation and without severe long term complications.

CONCLUSION

With the support of enough fibromembrane in pupillary area, anterior segment reconstruction and secondary posterior chamber IOL implantation can be performed, thus IOL suture fixation is not necessary, and its associated complications can be avoided.
