[Eccentric therapeutic penetrating corneal transplantation].

OBJECTIVE

To study the effective ways to restore sight and control the postoperative corneal astigmatism in eccentric penetrating keratoplasty.

METHODS

Marks were made on the meridian where the center of recipient bed was located, and at that meridian the distance between the external edge of recipient bed and the limbus (two point marking technique) was also marked. Afterward, the donor graft was cut down from a donor eye at the corresponding position and sutured on the recipient bed. This technique was performed on 23 cases with eccentric corneal ulcer and perforation, and they were followed up for 3 months to 2 years.

RESULTS

The grafts of 18 eyes remained transparent. The visual acuities were obtained > 0.1 in 16 cases, > 0.4 in 6 cases. Among them, visual acuity of 1.0 was obtained in 2 cases.

CONCLUSIONS

Two point marking technique can reduce the postoperative corneal astigmatism and obtain satisfactory visual acuity in eccentric penetrating keratoplasty. This technique is simple and easy to perform.
