Abstract

Purpose. Several surgical options have been described for the correction of postkeratoplasty astigmatism, but the results remain relatively unpredictable. We report the preliminary results of a new procedure for correcting high postkeratoplasty astigmatism termed, retrephination keratoplasty. Methods. The procedure entails full thickness retrephination along the original donor- recipient junction with careful resuturing in a combined interrupted and running fashion. Four eyes with severe postkeratoplasty astigmatism as well as myopia were enrolled and underwent the procedure. Results. Overall, a high preoperative cylinder ranging from 4.5 to 16.0 D (mean 9.0 D) was reduced to 1.0 to 3.75 D (mean 1.9 D) within the first postoperative month. At the last examination, (between 3 to 6 months) postoperative cylinder ranged from 0.5 to 3.5 D (mean 1.9 D). Spherical equivalent myopia was also reduced from a mean of -4.9 D (range -2.0 to -10.25) to +0.25 D (range +3.00 to -2.50) within the first postoperative month. At the last examination, (between 3 to 6 months) spherical equivalent myopia once again returned to its preoperative level at -4.7 D (range plano to -9.0). Overall there was a mean refractive cylinder reduction of 7.1 D resulting in a percentile reduction of astigmatism of 79%. Conclusion. Retrephination keratoplasty appears to be a fairly predictable alternative for correcting high postkeratoplasty astigmatism, while having little long-term effect on the level of myopia.
