摘要
目的探讨有晶状体眼前房型人工晶状体(PACIOL)植入术矫正超高度近视眼的有效性、安全性及可预测性。方法15例(29只眼)超高度近视眼患者植入Phakic6H2型PACIOL。术后观察患者的视力、屈光度数、眼压、角膜内皮细胞计数、晶状体位置、对比敏感度、眩光敏感度、手术并发症及视觉不良症状。结果术后3个月时患者裸眼视力≥0.5者占79.3%(23/29),6个月时占82.6%(24/29);术后3个月时患者最佳矫正视力≥0.8者占69.0%(20/29),6个月时占69.0%(20/29),裸眼视力及最佳矫正视力均较术前明显提高,差异有统计学意义(P<0.05)。术后3个月时患者裸眼视力较术前最佳矫正视力提高两行及两行以上者占70.0%(20/29),6个月时占72.4%(21/29)。术后3、6个月时屈光度中位数均为-1.00D,较术前均明显减少,差异有统计学意义(P<0.05)。患者术后3、6个月时眼压、角膜内皮细胞计数与术前相比,3个月与6个月相比,差异均无统计学意义(P>0.05)。PACIOL与角膜内皮和晶状体均保持了有效的安全距离,且弹性襻均位于前房角。术后6个月时,各频段对比敏感度和眩光敏感度较术前均明显提高,差异有统计学意义(P<0.05)。术后3个月时3只眼,6个月时2只眼均可见PACIOL表面炎性反应物沉积;1只眼瞳孔呈轻度椭圆形;8只眼发生PACIOL旋转。3例(5只眼)主诉夜间出现眩光症状,其他患者均无明显不适,满意程度较高。结论PACIOL植入术矫正超高度近视眼具有良好的有效性、安全性及可预测性,是补充角膜屈光手术不足的有效眼内屈光手术,但其远期效果有待进一步观察。
Objective To evaluate the efficacy, safety, and predictability of the implantation of phakic anterior chamber intraocular lens （PAC-IOL） for the correction of severe myopia. Methods In this prospective study, 15 cases （29 eyes） with myopia at - 15.00 - -24. 50 dioperts （D） were implanted with Phakic 6H2 PAC-IOL. Visual acuity, refraction, intraocular pressure, corneal endothelium, the PAC-IOL position, contrast sensitivity, glare sensitivity, operative complications and poor visual symptoms were observed. Results Postoperative uncorrected visual acuity 0.5 or better was presented in 79. 3% eyes （23/29） at 3 months and in 82. 6% eyes（24/29） at 6 months. Best corrected visual acuity 0. 8 or better was presented in 69. 0 % eyes （ 20/29 ） at 3 months and in 69.0% eyes （20/29） at 6 months, they were all significantly better than that of preoperative values （ P 〈 0.05 ） ; and there was no statistically significant difference between visual acuity at 3 months and 6 months （ P 〉 0. 05 ）. Compared with preoperative best corrected visual acuity, postoperative uncorrected visual acuity improved 2 lines or more in 70.0% of eyes （20/29）at 3 months and 72. 4% eyes （21/29）at 6 months. The mean postoperative spherical equivalent refraction was - 1.00D at 3 months, - 1.00D at 6 months, they were significantly lower than that of preoperative values （P 〈 0. 05 ） ; and there was no statistically significant difference of spherical equivalent refraction between 3 months and 6 months （P 〉 0. 05 ）. There were no statistically significant difference between pre- and post-operative mean intraocular pressure, corneal endothelial density （ P 〉 0.05 ） at 3 and 6 months. There was no significant difference of these data between 3 months and 6 months （ P 〉 0. 05 ）. The PAC-IOL was located （2. 341 ±0. 116 ） behind the central cornea, （0. 841 ±0. 140） nun in front of the crystalline lens. The footplates appeared to be correctly positioned in the anterior chamber a
