Abstract

PURPOSE
To investigate the effects of corneal tattooing on patients with a traumatic iris defect.
CASE SUMMARY
Corneal tattooing operation was performed on three patients (3 cases) with a traumatic iris defect. In case 1, the cornea was dyed with Davidson(R) marking dyes (Bradley Products Inc., MN, US) and the amniotic membrane with the central incision was permanently transplanted. In case 2, both corneal dyeing and permanent amniotic membrane transplantation were performed on the area of partial iris loss. In case 3, corneal dyeing was performed after the intrastromal cornea was dissected. Corneal reepithelization was found in the first 2 cases 12 and 9 days after amniotic membrane transplantation, respectively. Three months after the transplantation, all three cases showed an improvement in best corrected visual acuity (BCVA), with an increase of one or more lines on the Snellen Chart. Simultaneously, preoperative monocular contrast and glare were also found to beimproved in all three cases. In both cases 1 and 2, 60% of the initially used dyes still remained in the cornea 6 months after the surgery, and in case 3, 90% of the initial dye remained. Except for the moderate astigmatism found earlier after the surgery in case 3, no serious complications developed.
CONCLUSIONS
Corneal tattooing can improve the visual acuity and reduce glare in eyes with a traumatic iris defect and is cosmetically pleasing. Furthermore, corneal tattooing can be performed more easily and repeatedly than black diaphragm intraocular lens implantation.

  Figure 1. Photograph shows an eye having traumatic aniridia (A). We performed both corneal tattooing and amniotic membrane transplantation with the central incision (B). Corneal reepithelialization was completely achieved on the postoperative second week (C). This shows the well-stained cornea on the postoperative third month, especially in terms of retroillumination (D). (Case 1)

• 

  Figure 2. Photograph shows a partial iris defect on the 6~10 o’clock direction (A). We first performed the transplantation of the already tattooed amniotic membrane (B). Four years later, the tattooed dyes were almost discolored (C). So we performed the second corneal tattooing and then both permanent and temporary amniotic membrane transplantation (D). No epithelial defect was found on the second week after the above second operation (E). This shows that the dyes of corneal tattooing and iris color are well matched with each other (F).(Case 2)

• 

  Figure 3. Photograph shows an eye having traumatic aniridia (A). We performed intrastromal corneal tattooing (B). The state of the tattooed cornea was well-maintained throughout the follow-up observation (C). This PentacamⓇ Scheimfplug (Oculus inc., Germany) image shows the significant astigmatic eye on the postoperative first week (D). (Case 3)

  Figure 4. These graphs show the test results of contrast sensitivity and glare. All three cases showed an improvement at all four spatial frequencies of cycles per degree (cpd) on the postoperative 3rd month. (Contrast sensitivity was measured with the Standard Version of the CSV-1000E Chart (VectorVision, US) in accordance with applicable standards developed by Boxer and Krueger.12
