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(P0.05). 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.
