摘要
目的探讨ReSTOR多焦点折叠式人工晶状体的临床应用价值。方法将102例(176眼)年龄相关性白内障患者分为多焦点组46例(86眼)植入ReSTOR多焦点折叠式人工晶状体(Multifocal intraocular lens,MIOL)和单焦点组56例(90眼)植入SN60AT单焦折叠式人工晶状体(Singleintraocularlens,SIOL)行超声乳化白内障吸除人工晶状体植入术。检查患者术后的远、近视力、观察配镜情况、人工晶状体及视近调节力,角膜散光。随访时间3至9个月。结果术后3个月,MIOL组裸眼远视力≥0.6占97.67%(84/86),≥1.0占24.42%(21/86),与SIOL组比较差异无显著意义(P>0.05);MIOL组裸眼近视力≥0.6占84.88%(73/86),≥1.0占20.93%(18/86),MIOL明显优于SIOL组(P<0.01)。裸眼远视力≥0.6,同时裸眼近视力≥0.6者,MIOL组39眼,占45.35%;SIOL组3眼占3.33%,两者之间存在显著性差异。MIOL组双眼手术者中13.33%阅读时戴镜,SIOL组88.24%阅读时戴镜。手术源性角膜散光度数为0.32D。两组术后视觉异常症状均不明显;术后晶状体后囊膜混浊,MIOL组5只眼,SIOL组8只眼。结论多焦点人工晶状体植入术可使患者恢复良好的裸眼远近视力。
OBJECTIVE To evaluate the clinical effect of foldable multifocal intraocular lens(MIOL). METHODS One hundred and two patients( 176 eyes)with age - related cataract were divided into two groups. Group Ⅰ was the multifocal group:46 cases(86 eyes),and ReSTOR SA60D3 MIOL was implanted after phacoemulsification; Group Ⅱ was the monofocal group:56 cases(90 eyes) ,and Natural SN60AT monofocal intraocular lens(SIOL)was implanted after phacoemulsification. Postoperative examination included distant and near, uncorrected and bestcorrected visual acuity, pseudoaccommodation and measurement of corneal curvature. Follow- up period ranged from three months to nine months. RESULTS Three months after surgery,97.67 % eyes(84/86)in test group with ReSTOR MIOL had a distance visual acuity ≥ 0.6, and 24.41% (21/86) ≥ 1.0. It was not statistically different from the monofocal group( P 〉 0.05). Seventy - two eyes(83.72 % ) in test group had an uncorrected near acuity ≥ 0.5 and 19.77 % (17/86) ≥ 1.0. It was statistically better in the multifocal group compared with the monofocal group( P 〈 0.01). In MIOL, the eyes with beth the uncor- rected distance vision ≥ 0.8 and the uncorrected near vision ≥0.5 were in 45.35 %, but in SIOL were only in 3.33 %. The multifocal group was better. (P 〈 0.01). The rate of wearing spectacles was 13.33 % in test group and 88.24 % in case control group. The surgery - induced astigmatism in test group was 0.31 D, and no visual impairment appeared in beth groups. Posterior capsule opacification was seen in 5 eyes in test group and 8 in case control group. CONCLUSIONS The implantation of multifocal IOL has a good distance uncorrected visual acuity and better near visual acuity.
