【摘要】： 目的對(duì)比研究白內(nèi)障超聲乳化聯(lián)合人工晶狀體植入手術(shù)后非球面晶狀體與球面晶狀體眼的視覺(jué)質(zhì)量。 方法將我院2009年4月至2010年4月擬行超聲乳化白內(nèi)障吸除聯(lián)合人工晶狀體植入術(shù)的年齡相關(guān)性白內(nèi)障患者106例隨機(jī)分為2大組:非球面晶狀體組與球面晶狀體組。其中非球面晶狀體組隨機(jī)分別植入球差值-0.18μm非球面人工晶狀體(HOYA60AD),球差值-0.15～-0.18μm非球面人工晶狀體(STAAR KS-3AI),零球差非球面人工晶狀體(Rayner920H或Rayner970C),非恒定球差非球面人工晶狀體(Zeiss ZO);傳統(tǒng)球面人工晶狀體組隨機(jī)分別植入Rayner570C,XLSTABI-SKY,Hexavision HQ-201人工晶狀體。術(shù)后1個(gè)月對(duì)患者進(jìn)行裂隙燈下眼前段和眼底檢查、電腦驗(yàn)光及最佳矯正視力檢查,對(duì)除外眼部并發(fā)癥及裸眼視力或最佳矯正視力≥0.8患者行明視和暗視眩光及無(wú)眩光條件下的對(duì)比敏感度、6mm瞳孔直徑時(shí)眼的總體像差檢測(cè)和視功能與生存質(zhì)量問(wèn)卷調(diào)查。 結(jié)果術(shù)后1個(gè)月,7組人工晶狀體患者最佳矯正遠(yuǎn)視力差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05);明視、明視眩光中低空間頻率和暗視高空間頻率下4種非球面晶狀體組對(duì)比敏感度值總體高于球面晶狀體組。四種非球面晶體間比較:在明視及暗視有眩光或無(wú)眩光的各空間頻率下非恒定球差和球差值-0.15～-0.18μm非球面人工晶狀體組相較球差值-0.18μm非球面人工晶狀體組及零球差非球面人工晶狀體組對(duì)比敏感度值高,其中非恒定球差非球面人工晶狀體組在明暗視中、低空間頻率高,球差值-0.15～-0.18μm非球面人工晶狀體組在明視中高空間頻率及暗視低空間頻率高。三組球面晶狀體組比較:明視各空間頻率和暗視眩光低空間頻率時(shí)XLSTABI-SKY對(duì)比敏感度值高,暗視眩光中高空間頻率下Rayner570C相對(duì)較高,但與XLSTABI-SKY差異無(wú)統(tǒng)計(jì)學(xué)意義。Zeiss非球面晶體在明視和暗視有無(wú)眩光時(shí)中高空間頻率下相較Zeiss球面晶體對(duì)比敏感度值高。而Rayner非球面晶體在明視有無(wú)眩光的中低空間頻率下對(duì)比敏感度值高于Rayner球面晶體,但在明視高空間頻率及暗視各空間頻率下Rayner球面晶體對(duì)比敏感度值高于Rayner非球面晶體。術(shù)后1個(gè)月,瞳孔直徑6mm情況下非球面人工晶狀體組的總眼球差為(0.17士0.25)μm,球面人工晶狀體組為(0.31士0.24)μm,差異有統(tǒng)計(jì)學(xué)意義(P0.05)。VF/QOL問(wèn)卷調(diào)查顯示7組人工晶狀體眼之間的視功能與生存質(zhì)量差異有統(tǒng)計(jì)學(xué)意義(P0.05 )。 結(jié)論超聲乳化白內(nèi)障吸除聯(lián)合人工晶狀體植入術(shù)后,非球面人工晶狀體相較球面晶狀體可以降低總眼球差,相對(duì)提高視覺(jué)對(duì)比度;其中非恒定球差非球面人工晶狀體和球差值-0.15～-0.18μm非球面人工晶狀體與本研究中其他非球面晶狀體相比,能夠相對(duì)明顯的提高白內(nèi)障患者術(shù)后明暗對(duì)比敏感度,改善患者視覺(jué)質(zhì)量。
[Abstract]:Objective to compare the visual quality of aspherical lens and spherical lens after phacoemulsification combined with intraocular lens implantation. Methods from April 2009 to April 2010, 106 patients with age-related cataract undergoing phacoemulsification and intraocular lens implantation were randomly divided into two groups: aspheric lens group and spherical lens group. The aspheric lens group was randomly implanted with spherical difference (-0.18 渭 m), spherical difference (-0.15 渭 m) -0.18 渭 m aspheric intraocular lens (STAAR KS-3AI), zero spherical aberration aspheric intraocular lens (Rayner920H or Rayner970C) and unsteady spherical aberration aspheric intraocular lens (Rayner920H or Rayner970C). The conventional spherical intraocular lens (Zeiss ZO);) group was randomly implanted with Rayner 570 Con XLSTABI-SKYY Hexavision HQ-201 intraocular lens. One month after operation, the patients were examined with slit lamp under anterior segment and fundus, computer optometry and best corrected visual acuity (BCVA). The total aberration, visual function and quality of life (QOL) of eyes with 6 mm pupil diameter were measured with contrast sensitivity and dark glare and without glare in patients with ocular complications and uncorrected visual acuity or best corrected visual acuity (BCVA) 鈮，
