Three-millimeter incision descemet stripping endothelial keratoplasty using sodium hyaluronate (healon): a survey of 105 eyes.

PURPOSE

To report a Descemet stripping automated endothelial keratoplasty (DSAEK) insertion technique using sodium hyaluronate (Healon) and describe complication rates, visual acuity, and endothelial cell counts.

METHODS

A retrospective analysis of 105 eyes in 91 patients undergoing DSAEK. Ninety-three eyes had Fuchs endothelial dystrophy, 11 had bullous keratopathy, and 1 had iridocorneal endothelial (ICE) syndrome. We noted pre- and postoperative visual acuity at 3 and 6 months, endothelial cell counts, and complications, including graft detachment rates. Thirty-six of 141 eyes met exclusion criteria of prior incisional corneal, glaucoma, or retinal surgery.

RESULTS

Because of graft detachment, 29 of 105 eyes (28%) required a re-bubble procedure at day 1 or week 1. Five of 105 grafts (4.8%) failed. Of note, in the last 35 cases, there were no graft failures and 5 detachments (14%). Twenty-eight percent of patients were 20/40 or better preoperatively compared with 49% at 3 months and 52% at 6 months. Excluding eyes with other ocular comorbidities (34), 62% were 20/40 or better at 3 months and 72% were 20/40 or better at 6 months. Postoperative endothelial cell counts were available for 52 eyes with an average cell loss of 44% at an average of 9.4 months.

CONCLUSIONS

DSAEK is an effective treatment for endothelial dysfunction, but the learning curve is steep. Anterior chamber stability, graft positioning, and small incision insertion are advantages to our technique. Disadvantages include a relatively high endothelial loss and dislocation rate. Minimizing endothelial cell loss and graft dislocation continue to be important goals for successful DSAEK.
