【摘要】：引言根據(jù)患者角膜球面像差選擇不同球面像差的人工晶狀體,滿足患者對于視覺質(zhì)量的要求,已經(jīng)被許多專家認(rèn)真研究和認(rèn)可。本論文就是根據(jù)角膜球面像差為患者植入人工晶狀體,以期達(dá)到術(shù)后最佳目標(biāo)球差值,達(dá)到最佳視覺效果。目的植入不同球面像差的人工晶狀體后,對比不同的全眼球面像差下人眼的視覺質(zhì)量。方法收集2015年11月~2016年7月在鄭州大學(xué)第一附屬醫(yī)院眼科本治療小組接受白內(nèi)障超聲乳化+IOL植入術(shù)的年齡相關(guān)性白內(nèi)障患者55例63眼,患者年齡范圍為50~70歲,除了年齡相關(guān)性白內(nèi)障以外,無其他眼部疾病,散光1.5D。分別依據(jù)患者術(shù)前角膜球面像差(spherical aberration,SA)植入不同SA的IOL,根據(jù)術(shù)后全眼SA值,將患者分為三組,A組術(shù)后的全眼SA為(-0.2±0.05)μm,B組為(0±0.03)μm,C組為(+0.1±0.03)μm。比較三組術(shù)后3月的裸眼視力(uncorrected visual acuity,UCVA)、最佳矯正視力(best-corrected visual acuity,BCVA)、全眼總高階像差(high order aberration,HOA)、調(diào)制傳遞函數(shù)值(modulation transfer function,MTF)以及患者滿意度調(diào)查。結(jié)果三組術(shù)后3月的UCVA,差異無統(tǒng)計學(xué)意義(P=0.153);三組術(shù)后3月的BCVA,差異無統(tǒng)計學(xué)意義(P=0.999)。術(shù)后3月的全眼HOA比較,三組之間差異無統(tǒng)計學(xué)意義(P=0.268)。在5周/度(c/d)、10周/度(c/d)、15周/度(c/d)、20周/度(c/d)、25周/度(c/d)、30周/度(c/d)的空間頻率下,三組術(shù)后3月的MTF值,A組B組C組,差異有統(tǒng)計學(xué)意義(P0.05)。三組患者滿意度調(diào)查A組B組C組,差異有統(tǒng)計學(xué)意義(F=19.700,P=0.000)。結(jié)論根據(jù)角膜球面像差個性化植入IOL,使得術(shù)后全眼球面像差為+0.1μm時,視覺質(zhì)量較好,滿意度較高。
[Abstract]:The introduction of the artificial lens with different spherical aberration according to the spherical aberration of the patient's cornea meets the requirements of the patient for the visual quality, and has been carefully studied and approved by many experts. In this paper, the artificial lens is implanted into the patient according to the spherical aberration of the cornea, so as to achieve the best target ball difference and achieve the best visual effect. Objective To compare the visual quality of human eyes with different spherical aberration after implantation of the artificial lens with different spherical aberration. Methods From November 2015 to July 2016,55 cases of age-related cataract with cataract phacoemulsification and IOL implantation were collected in the first affiliated hospital of Zhengzhou University in July,2016. The age range of the patients was 50-70 years. In addition to the age-related cataract, No other ocular diseases, astigmatism 1.5D. The patients with different SA were implanted according to the preoperative corneal spherical aberration (SA), and the patients were divided into three groups according to the postoperative full-eye SA value. The whole-eye SA in group A was (-0.2-0.05). m The group C was (+ 0.1-0.03). m u.m. The three groups were compared with the three-month open-hole vision (UCVA), best-corrected visual acuity (BCVA), total-eye total high-order aberration (HOA), modulation transfer function (MTF), and patient satisfaction survey. Results There was no significant difference in UCVA between the three groups (P = 0.153). The difference of BCVA and the difference in the three groups was not significant (P = 0.999). There was no significant difference between the three groups (P = 0.268). At the spatial frequency of 5 weeks/ degree (c/ d),10 weeks/ degree (c/ d),15 weeks/ degree (c/ d),20 weeks/ degree (c/ d),25 weeks/ degree (c/ d), and 30 weeks/ degree (c/ d), the MTF values of group A and group B were statistically significant (P0.05). There was a significant difference between group C and group B in group B (F = 19.700, P = 0.000). Conclusion The IOL is implanted according to the spherical aberration of the cornea, so that the visual quality is better and the degree of satisfaction is higher when the aberration of the whole eyeball is + 0.1. m
