[A clinical study on reducing immunologic rejection in combining corneal lamellar autografting with allografting].

OBJECTIVE

To reduce the rate of immunologic rejection, corneal lamellar autografting with allografting were combined, making immune cells less attack on allograft.

METHODS

The pterygium having encroached upon the pupillary area was removed surgically, and the combination of autograft with allograft was transplanted on the peripheral and central cornea in 23 cases (24 eyes). The control group of 13 cases (13 eyes) was established in which the pterygium and dermoids were removed, and lamellar allografts were transplanted. The rate of rejection and their effects were compared.

RESULTS

The rate of transparent autograft and allograft was 100%, no rejection and recurrence of pterygium occurred in any case in the combined group, while in the control group, the rejection rate was 30.8% and recurrence rate, 20.0%.

CONCLUSION

The combination of lamellar autografting with allografting can reduce the rate of rejection and recurrence of pterygium.
