AIM:To study the effects of multifocal intraocular lens implantation (MIOL) in cataract refrective surgery.METHODS:After small incision phacoemulsification,MIOL was inserted into the eyes of 19 cases (25 eyes),monofocal intraocular lens (SIOL) was inserted into the eyes of 14 cases (20 eyes).30-52 months after intraocular lens implantation,near visual acuity,intermediate visual acuity at different contrast and postoperative spectacle dependency were evaluated.RESULTS:At 40cm 100% contrast,MIOL got 54.64±10.80 scores and SIOL got 47.05±6.39 scores.There was statistically significant differences between MIOL and SIOL (P<0.05).At 40cm 10% contrast,MIOL got 42.60±6.47 scores and SIOL got 34.55±5.86 scores.There was statistically significant differences between MIOL and SIOL (P<0.05).Score of visual acuity at 63cm and 100cm at different contrast was no significantly statistical difference between two groups.Multifocal group of near use had a higher spectacle independence rate.CONCLUSION:MIOL provides a satisfactory vision at different contrast.
