可调节式后房型人工晶体植入的临床观察

目的 探讨可调节式后房型人工晶体植入术后的临床疗效及调节效果.方法 将48例(52只眼)单纯性白内障用超声乳化摘除并植入1CU可调节式后房型人工晶体,术后观察远、近视力,角膜水肿,瞳孔,晶状体囊袋,以及视远、视近时调节力变化情况.结果 随访3～6个月,术后1周远视力1≥0.5者46只眼(88.46%),术后3个月远视力≥0.5者49只眼(94.23%),术后6月远视力≥0.5者51只眼(98.07%),术后1周近视力≥Jr5者37只眼(71.15%),术后3个月近视力≥Jr5者43只眼(82.69%),术后6个月近视力≥Jr5者47只眼(90.38%).术后1周观察52只眼均无角膜水肿;瞳孔圆,对光反射敏感;晶状体囊袋无缩小,环形撕囊口圆,位于晶状体囊袋正中,直径约5mm;客观法检查视远、视近调节力变化为(0.95±0.36)D.结论 这种可调节式后房型人工晶体早期观察的结果具有良好术后视功能,具有很好组织耐受性,在晶状体囊袋中稳定,居中性好,并发症少,具有一定调节范围.但植入1CU对手术仪器及手术医师要求较高,手术后的长期效果仍需要观察:随手术后的时间延长视力及调节力的变化及稳定性情况.

The Clinical efficacy of accommodative PC-IOL after implantation

Objective To evaluate the clinical effectiveness and accommodative range after implanting the ICU accommodative PC-IOL (ICU). Methods 48 cases (52eyes) had phacoemulsification and implantation of 1CU (Human Optics). Naked and best corrected distant acuity, naked and best corrected near acuity at 35cm were determined and the change in the corneal , IOP , pupil. Results Naked distant acuity of a week were ≥ 0.5 have 46 eyes ( 88.46 % ), at 3 months were > 0.5 have 49 eyes (94.23 % ) ,at 6 months were ≥ 0.5have51 eyes ( 98.07 % ).Naked near acuity at 1 week≥ Jr5 have 37 eyes (71.15%), at3 months were ≥ Jr5 have 43 eyes (82.66 % ), at 6 months were ≥ Jr5 have 47 eyes (90.38 % ). Naked 52 eyes corneal no hydrops ,reflex papillary was brisk ,the lens capsule ring was centered and diameter is 5ram .The accommodative range ,The diopter measured byObjective techniques was 0.95D±0.36D. Conclusions In the present study the ICU accommodative PC-IOL showed that the eyes with ICU had good visual acuity. The 1CU accommodative PC-IOL after implantation had good centered and stable and no IOL-Speeific Complications and increased accommodative range move than the Control group with conventional IOLS, Further research is necessary to observe the changes of refraction of ICU with the time longer after operation.
