[Gonioscopy after foldable lens implantation through a sutureless tunnel incision].

OBJECTIVE

To investigate the changes of internal incision and the peripheral iris after cataract surgery through a sutureless tunnel incision.

METHOD: Gonioscopy was performed on 58 eyes of 56 cases having undergone phacoemulsification and foldable intraocular lens implantation through a 3.5 mm sutureless tunnel incision.

RESULTS

Gonioscopic findings showed that the internal incision was located in clear cornea anterior to Schwalbe's line in 56 eyes and just at the line in 2 eyes. Forty-two eyes (72.41%) had a smooth linear internal incision. There were small tags or curls in 14 eyes (24.14%). The Descemet's membrane detachments were detected in 5 eyes (8.62%) and peripheral iris anterior synechiae in 2 eyes (3.45%).

CONCLUSION

The results suggest that the incidence of peripheral iris anterior synechiae be relatively low, however Descemet's membrane detachments easily occur in foldable lens implantation through sutureless tunnel incisions.
