摘　　要：目的 :评价透明晶状体屈光手术的有效性、预测性和安全性。方法 :对屈光不正患者 5 8例 87眼行透明晶状体超声乳化摘除联合折叠式人工晶状体植入。患者年龄 2 5～ 73岁 ,平均 5 4 .32岁。将病例分为 3组 ,A组为高度近视共 6 1眼 ,眼轴长度 (2 9.5 7± 2 .10 )mm ,等效球镜度数 (- 11.93± 4 .6 4 )D ,植入人工晶状体屈光度 (+9.0± 3.82 )D ;B组为远视共 17眼 ,眼轴长度 (2 2 .39± 0 .96 )mm ,等效球镜度数 (+2 .2 9± 1.0 5 )D ,植入人工晶状体屈光度 (+2 2 .70± 2 .0 8)D ;C组为屈光参差共 9眼 ,眼轴长度 (2 8.4 8± 1.77)mm ,屈光参差度数 (- 11.2 5± 5 .38)D ,植入人工晶状体屈光度 (+10 .6 2±3.6 2 )D。随访 3～ 36个月。结果 :术后最佳矫正视力 87眼均达到或超过术前最佳矫正视力 ;术后裸眼视力达到或超过术前最佳矫正视力者在A、B、C组分别占 86 .89%、94 .12 %和88.89% ;术后裸眼视力 0 .5以上者分别为 5 4 .10 %、4 1.18%和 5 5 .5 6 % ;术中未发生后囊破裂。随访中 12眼发生后囊混浊 ,未发现视网膜脱离、黄斑囊样水肿等并发症。结论 :透明晶状体屈光手术与目前的角膜屈光手术相比 ,可能更适宜于中年以上不愿戴镜和戴镜不能矫治的屈光不正患者 。Objective:With the development of phacoemulsification techniques and instrumentation,the incidence of retinal detachment after phacoemulsification in high myopia has been reduced to less than 1%. So phacoemulsification may be used to treat some types of ametropia. This study evaluates the effectiveness,predictability and safety of clear lens refractive surgery for the treatment of myopia,hyperopia and anisometropia.Methods:Phacoemulsification and flexible intraocular lens(IOL) implantation were performed on the clear lenses of 87 eyes with ametropia in 58 patients(20 males,38 females). Low phacoemulsification energy and high negative aspiration pressure were used in surgery. Flexible IOLs with 6 mm optics were implanted. The average age of the patients was 54.32 years(25～73 years). The patients were divided into 3 groups. There were 61 eyes with high myopia in Group A. The mean axial length was(29.57±2.10)mm,the mean refractive error(spherical equivalent) was(-11.93±4.64)D,and the mean calculated power of the implant was(+9.0±3.82)D. There were 17 eyes with hyperopia in Group B. The mean axial length was(22.39±0.96)mm,the mean refractive error(spherical equivalent) was(2.29±1.05)D,and the mean calculated power of the implant was(+22.70±2.08)D. And there were 9 eyes with anisometropia in Group C. The mean axial length was(28.48±1.77)mm,the mean refractive error for anisometropia was(-11.25±5.38)D,and the mean calculated power of the implant was(+10.62±3.62)D. Fundus examination was performed to locate retinal tear and retinal lattice degeneration before surgery. One patient was treated with retinal photocoagulation for peripheral retinal tear. Accurate A scan measurement of the axial length of the eye and keratometry were performed by skilled technicians. The implant power of the IOL was calculated using the SRK formula. The refractive power of an IOL was determined with predicted postoperative refractive error as -2 D to -3 D in Groups A and B. The predicted postoperative refractive error was -0.75 D
