【摘要】： 目的通過比較白內(nèi)障超聲乳化聯(lián)合植入Acrysof ResToR及Acrysof Natural.Array SA-40N術(shù)后人工晶狀體眼(IOL)的視功能狀態(tài),評價(jià)Acrysof Re sToR多焦點(diǎn)人工晶狀體(MIOL)的臨床效果。 方法隨機(jī)化臨床試驗(yàn),選擇合適的年齡相關(guān)性白內(nèi)障患者,其中ReSTOR組：30例36眼；Natural組：28例30眼,；Array組50例60眼。觀察三組患者術(shù)后3月視力,包括未矯正遠(yuǎn)視力(UCDVA)、未矯正近視力(UCNVA)、最佳矯正遠(yuǎn)視力(BCDVA)、最佳矯正近視力(BCNVA)、遠(yuǎn)矯正下的近視力(DCNVA)、中間距離視力(40cm,60cm,80cm),對比敏感度(CS)、焦點(diǎn)深度,并進(jìn)行關(guān)于視覺癥狀、戴鏡率和滿意度的問卷調(diào)查。 結(jié)果術(shù)后3月,ResToR組在UCDVA.BCDVA.BCNVA和Natural組Array組無顯著差異(P0.05),但在UCNVA,DCNVA優(yōu)于Natural、Array(P0.05)。關(guān)于中間距離視力,ResToR和Array無顯著性差異(P0.05),明顯優(yōu)于Natural組(P0.05)。ResToR在術(shù)后屈光狀態(tài)(球鏡、柱鏡)和Natural.Array均無差異。在焦點(diǎn)深度方面,ReSTOR和Array,它們的焦點(diǎn)深度范圍無差異,且波峰、波谷出現(xiàn)的位點(diǎn)基本一致。ReSTOR的焦點(diǎn)深度范圍5.88D,Natural的焦點(diǎn)深度范圍1.88D,有統(tǒng)計(jì)學(xué)意義(P0.05).對比敏感度方面,ReSTOR和Array在各個(gè)空間頻段無統(tǒng)計(jì)學(xué)差異(P0.05)。ReSTOR組各空間頻段均低于Natural組,但是除了高空間頻段(18cpd)外,其余差異無顯著意義(P0.05)。ReSTOR和Array植入術(shù)后的視覺癥狀,均以眩光和光暈為主,兩者無顯著性差異。ReSTOR組患者術(shù)后受眩光、光暈影響較Natural組明顯(P0.05),但均可忍受。ReSTOR組視近時(shí)“戴鏡率”低于Natural組,差異有統(tǒng)計(jì)學(xué)意義(P0.05)。ReSTOR和Array“戴鏡率”差異無顯著意義(P0.05)。 結(jié)論：新型衍射型多焦點(diǎn)人工晶體ReSTOR能提供良好的全程視力,有效減低患者對老視鏡的依賴,提高白內(nèi)障患者術(shù)后的視覺質(zhì)量。
[Abstract]:Objective to compare the effect of phacoemulsification combined with implantation of Acrysof ResToR and Acrysof Natural.Array SA-40N on intraocular lens (IOL). IOL). To evaluate the clinical effect of Acrysof re sToR multifocal intraocular lens. Methods A randomized clinical trial was conducted to select suitable age-related cataract patients, including 30 cases (36 eyes) in ReSTOR group. Natural group: 28 cases (30 eyes); The visual acuity of the three groups was observed on March, including UCDVAV without correction and UCNVA without corrected near visual acuity (UCNVA) in 50 patients (60 eyes) in Array group. The best corrected distant visual acuity (BCDVAV), the best corrected near visual acuity (BCNVAV), the near visual acuity (DCNVAV) and the intermediate distance visual acuity (40 cm ~ 60 cm ~ (80 cm)). Contrast sensitivity, depth of focus, and a questionnaire on visual symptoms, wear rate, and satisfaction. Results on March, there was no significant difference between the UCDVA.BCDVA.BCNVA group and the Natural group in Array group (P 0.05), but in UCNVA. DCNVA was better than that of natural Arraya (P 0.05). There was no significant difference between ResToR and Array in the middle distance visual acuity (P 0.05). Compared with Natural group, there was no significant difference in refractive state (spherical, cylindrical) and Natural.Array, but in focal depth. The focal depth range of ReSTOR and Arrayhas no difference, and the peaks and troughs are basically consistent with the focal depth range of .ReSTOR (5.88D). The focal depth range of Natural was 1.88D, which was statistically significant (P 0.05). Contrast sensitivity. There was no statistical difference between ReSTOR and Array in each spatial frequency band. The spatial frequency of ReSTOR and Array group was lower than that of Natural group. But with the exception of high spatial frequency band (18cpdd), there was no significant difference in visual symptoms after P0.05 or Array implantation. Glare and halo were the main visual symptoms. There was no significant difference between the two groups. The patients in the rest group suffered from glare and the effect of halo was significantly higher than that in the Natural group (P 0.05). However, the "wear rate" in the. Rest group was lower than that in the Natural group. The difference was statistically significant (P 0.05). There was no significant difference between Array (P 0.05) and Array (P 0.05). Conclusion: the new diffractive multi-focus intraocular lens (ReSTOR) can provide good visual acuity in the whole process, reduce the dependence of the patients on the presbyopia, and improve the visual quality of the cataract patients after operation.
