AIM: To observe the clinical effects of the sutureless intraocular suspended implantation of foldable three-piece acrylic aspheric posterior chamber lens(Tecnis)through clear corneal incision.

METHODS: A total of 21 patients(24 eyes)with non or unintact capsule that underwent the intraocular suspended implantation of foldable three-piece acrylic aspheric posterior chamber lens(Tecnis)through clear corneal incision were observed and compared clinically to evaluate the clinical effects of this operative method. The observation and comparison were made on the parameters including visual acuity, intraocular reaction and lens situation by ultrasound biomicrography(UBM)before and after the operation.

RESULTS:A 3-12 months(6.5 months on average)follow up shows significant improvement(P<0.01)of both the uncorrected and corrected visual acuity of 24 eyes. The corrected postoperative visual acuity were 1.0-1.5(8 eyes, 33.3%), 0.5-0.9(13 eyes, 54.2%)and 0.1-0.4(3 eyes, 12.5%), respectively. There was no statistical difference in the distance from the plane of artificial lens body to corneal endothelium, and the distance from ciliary process to corneal endothelia(P>0.05)in UBM photos after operations. All of 24 eyes were successfully conducted intraocular lens implantation without serious, intraocular infections or inflammations, no complications like cyclodialysis or retinal detachment. Only a few cases present temporary increase of intraocular pressure.

CONCLUSION: The sutureless intraocular suspended implantation of foldable three-piece acrylic aspheric posterior chamber lens(Tecnis)through 3.0-6.0mm clear corneal incision is an advisable remedy for capsule rupture failure during phaco-emulsification and an advisable operation for the dislocation of crystalline lens resulted from trauma or congenital cataract. The procedure can improve visual acuity safely and effectively without obvious complications. Its long-term effect needs long-term follow-up observation.
