Abstract

Purpose

To report a patient with a pseudophakic bullous keratopathy (PBK) who underwent Descemet's membrane stripping endothelial keratoplasty (DSEK) with manual preparation of the donor corneal graft.

Case summary

A 61-year-old female presented with visual disturbance in her right eye. Five months prior, she was treated with phacoemulsification and intraocular lens exchange surgery of the right eye, and a very severe corneal edema was revealed by slit-lamp examination. We diagnosed PBK and planned DSEK with manual preparation of a donor corneal graft because of the non-availability of a microkeratome or a femtosecond laser. After making the corneal graft using an artificial anterior chamber, crescent knife and cornea dissector, the keratoplasty proceeded using the graft. Three months after surgery, her graft was well-maintained on the right eye. The patient's visual acuity was 0.3, and the corneal endothelial cell count was 1,844/mm².

Conclusions

Manual preparation of the donor corneal graft for DSEK is suitable as a second choice treatment method when the availability of surgical devices is limited.

Figures and Tables

Figure 1

(A) Slit lamp photography of the right eye on the first visit shows severe corneal stromal edema. Severe descemet's folds are also shown on the right eye. (B) Slit lamp photography of the right eye 5 months after manual prepared Descemet's membrane stripping endothelial keratoplasty. The margins of the centrally adhered posterior corneal disk are seen. Some residual stromal edema is visible in the posterior corneal disk, and central corneal thickness is 571 µm.

It is well attached to the posterior surface of the recipient cornea. (B) One month after the surgery, we can find the well-maintained donor graft.
