Abstract:AIM: To investigate the effect of viscoelastic agents on the corneal laceration suturing.
METHODS:Totally 146 cases(146 eyes)of corneal laceration were randomly divided into experimental group and control group. Appropriate amount of viscoelastic agents were injected into anterior chamber during corneal laceration suturing for 73 cases of the experimental group. While, the stitching process without application of viscoelastic agent in 73 cases of the control group. Then observed the corneal astigmatism and the iris anterior synechia occurrence rate after operation in the two groups.
RESULTS:Iris anterior synechia occured in 2 cases(2.7%)of the experimental group, but in 26 cases(35.6%)of the control group, postoperatively.The difference of the iris anterior synechia occurrence rate between the two groups was significant(P<0.05). The postoperative average corneal astigmatism of the experimental group was(1.29 ± 0.25)D, of the control group was(2.43±0.39)D. The difference of the corneal astigmatism between the two groups was significant too(P<0.05), which means the experimental group was lower than the control group on postoperative corneal astigmatism.
CONCLUSION:Viscoelastic agents play a significant adjunct role during corneal laceration suturing,such as they can effectively separate the adhesions between intraocular tissue and wound, make the corneal suture more precisely and reduce postoperative corneal astigmatism and other complications, which is of benefit to visual function recovery.
