两种非球面衍射多焦点人工晶状体植入术后视觉质量评价
Clinical visual quality study after implantation of two kinds of AcrySof ReSTOR aspherical IOL
摘要
Abstract
AIM: To evaluate the clinical visual quality after implantation of two kinds of AcrySof ReSTOR aspherical intraocular lens(IOL), and also to analyze the relative factors.METHODS: Forty patients with cataract (80 eyes) were divided into two groups: Group A(20 patients, 40 eyes): implanted with AcrySof ReSTOR + 3D(SN6AD1); Group B (20 patients, 40 eyes): implanted with AcrySof ReSTOR + 4D ( SN6AD3 ). Uncorrected distance visual acuity ( UCDVA ), uncorrected intermediate visual acuity ( UCIVA), uncorrected near visual acuity( UCNVA) were observed at 1 day, 1 week, 1 month, 3 month postoperatively. BCDVA, BCNVA, DCNVA, DCIVA, aberration, contrast sensitivity were examined at 3 month postoperatively. Binocular defocus curve-a full range of vision also were examined at 3 month postoperatively.RESULTS: All of the eyes had best UCDVA, but, group A showed statistical superiority in UCIVA at 1 day, 1 week, 1 month and 3 month (P<0. 05). It showed no statistical difference in UCNVA at 1 week, 1 month and 3 month, but except 1 day after surgery. Both two groups showed no statistical difference in BCDVA, BCNVA, DCNVA, DCIVA, aberration and contrast sensitivity at 3 month postoperatively(P>0. 05). Binocular defocus curve-a full range of vision showed that group A had two focuses at+0. 0D and -3. 0D, but, besides the two focus:+0. 0D and -2.5D, group B also had a platform level from -2.0D to -2.5D. Questionnaire showed that both of two groups had no obviously visual disturbance (t= -0. 87, P>0. 05). But, aspherical AcrySof ReSTOR + 3D IOL showed more superior vision performance in intermediate vision.CONCLUSION: The aspherical AcrySof ReSTOR+3D IOL can provide patients with excellent outcomes in distant, intermediate and near vision. Compared with aspherical AcrySof ReSTOR + 4D, it shows more superior vision performance in intermediate vision, reduces the dependence on spectacles and improves the quality-of -life.关键词
