To evaluate retrospectively the outcomes of 15 consecutive mushroom-shaped penetrating keratoplasties performed by using excimer laser for both the recipient bed and the fresh donor corneas.
Fifteen eyes of 14 patients who underwent excimer laser mushroom-shaped penetrating keratoplasty from October 13, 2010, to October 14, 2011, were included in our retrospective study. Eight were men and 6 were women, with a mean age of 31.45 ± 6.52 (range 27-65) years. Eleven (73.3%) had postinfective central deep corneal scar; 4 (26.7%) had severe keratoconus with Descemet opacity.
The mean follow-up was 11.9 ± 2.7 months. The mean preoperative best-corrected visual acuity (BCVA) was 0.15 ± 0.16; the postoperative BCVA was 0.69 ± 0.24 after 12 months with a mean refractive astigmatism of 1.8 ± 1.1 D. The mean preoperative endothelial cell count of the donor corneas was 2297.0 ± 189.7 cells/mm²; after 12 months, it was 1906.5 ± 165.8 with a decrease of 17.0%. No intraoperative complications occurred.
Our results showed that excimer laser mushroom penetrating keratoplasty is safe. Furthermore, it does not appear to influence the visual outcomes of the penetrating keratoplasty surgery. This technique is useful for those who use an excimer laser.
回顾性评估连续15例使用准分子激光对受体床和新鲜供体角膜进行蘑菇形穿透性角膜移植术的结果。
我们的回顾性研究纳入了2010年10月13日至2011年10月14日期间接受准分子激光蘑菇形穿透性角膜移植术的14例患者的15只眼。其中男性8例,女性6例,平均年龄31.45±6.52岁(范围27 - 65岁)。11例(73.3%)患有感染后中央深层角膜瘢痕;4例(26.7%)患有严重圆锥角膜伴后弹力层混浊。
平均随访时间为11.9±2.7个月。术前平均最佳矫正视力(BCVA)为0.15±0.16;术后12个月BCVA为0.69±0.24,平均屈光性散光为1.8±1.1D。供体角膜术前平均内皮细胞计数为2297.0±189.7个/mm²;12个月后为1906.5±165.8,减少了17.0%。术中无并发症发生。
我们的结果表明准分子激光蘑菇形穿透性角膜移植术是安全的。此外,它似乎不影响穿透性角膜移植手术的视觉效果。该技术对准分子激光使用者有用。
