Abstract:AIM:To evaluate the clinical efficacy after the implantation of SN6AD1 multifocal intraocular lens(MIOL). METHODS:After the phacoemulsification, SN6AD1 MIOL was inserted into 65 eyes of 44 patients. The mean follow-up duration was 3 to 6 months. The visual acuity, corneal astigmatism, defocus testing, rate of off-glasses and patient satisfaction were observed. RESULTS:At 3 months after the implantation, the average distant, intermedia and near visual acuity were satisfying. There was no statistically significant difference between the preoperative corneal astigmatism and corneal astigmatism at 3 months after the operation(P>0.05). The defocus curve showed double-peak shape,of which one peak was at the point of 0D and the other peak was on the plateau of -2.00--2.50D. Thirty-nine (89%) patients took off their glasses, who could engage in various distance work. CONCLUSION:SN6AD1 MIOL can offer a better whole range of vision and increase the rate of off-glasses.
