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1a90.3%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。
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.
