Abstract
AIM: To investigate the clinic results, safety and predictability of conductive keratoplasty (CK) for correcting presbyopia.
METHODS: CK was performed in 31 patients (40 eyes) with presbyopia and the follow-up was one year. The preoperative sphere was ＋0.50~＋2.50D and cylinder was 0.00~＋0.75D. For distance vision correction, the target refraction was 0.00~-0.50D in the dominant eye. For near vision，the target was better than J3 and refraction was -1.50～-2.50D in the non-dominant eye.
RESULTS: At one year after surgery, 61.3% of patients had binocular distance UCVA of 20/25 or better along with J3 or better near，and along with J4 or better near was 74.2%, respectively. There was significant diffe-rence of binocular UCVA along with better near vision between preoperative and postoperative (P＜0.01). 45.0％ and 82.5％ of CK eyes had a manifest refractive spherical equivalent (MRSE) within ±0.5D and ±1.0D of intended correction，respectively. Postoperative cylinder within ±1.0D was 87.5% in CK eyes. Postoperative contrast sensitivity function was no significant decrease than preoperative（P＞0.05）. There was no drawdown of BSCVA and no serious dry eye syndrome. About 90% of patients were satisfied with the results at one year after surgery.
CONCLUSION: CK with monovision are effective surgery for presbyopia. Furthermore, their long-term results and stability are needed more time to be observed.

摘要
目的：探讨应用单眼视原理采用传导性角膜成形术（Conductive keratoplasty，CK）治疗老视的临床效果、安全性及可预测性。
方法：选择31例（40眼）有明显老视症状的患者，术前屈光度球镜+0.50～＋2.50D，散光≤＋0.75D，采用CK进行治疗，术后预期目标屈光度主导眼矫正为0.00～-0.50D，非主导眼术后目标屈光度为-1.50～-2.50D，且近视力≥0.5(J3)，术后随访1a以上。
结果：术后1a双眼裸眼远视力≥0.8且近视力≥0.5（J3）或近视力≥0.33(J4)者分别为61.3％，74.2%；与术前相比均有显著性差异(P＜0.01)；术后1a等效球镜屈光度与预期目标差值在±0.50D、±1.00D以内者分别为45.0％，82.5％；术后1a术眼散光度在±1.00D以内者为87.5％；术后双眼各空间频率对比敏感度与术前相比较差异无统计学意义（P＞0.05）；术后1a无最佳矫正视力下降，无严重干眼症的发生；术后1a 90.3%的患者表示满意。
结论：应用单眼视原理采用CK治疗老视取得了较好的临床疗效，但其远期疗效和稳定性有待进一步观察。
