AIM: To compare the visual quality after different multifocal lens(MIOL)implantation in cataract patients.

METHODS:Totally 78 cases(78 eyes)of cataract patients who receiving phacoemulsification and implantation of different MIOL were enrolled from February 2016 to June 2017 in our hospital. According to the different type of implanted MIOL, the 78 cases(78 eyes)were divided Group A, B and C, each group was 26 cases(26 eyes). Patients in the Group A were implanted regional refraction MIOL SBL-3; patients in the Group B implanted step progressive diffraction MIOL SN6AD1; patients in the Group C implanted all-optical plane diffraction MIOL Tecnis ZMB00. The visual acuity, contrast sensitivity, defocus testing, contrast visual acuity and satisfaction of visual quality were compared in 3 groups at postoperative 3mo.

RESULTS: There was no statistically significant difference in postoperative adverse reactions between the three groups(P>0.05). There was statistical difference in uncorrected intermediate visual acuity, uncorrected near visual acuity, distance-corrected intermediate visual acuity and distance-corrected near visual acuity in 3 groups(P<0.05), and those in the Group C were significantly worse than those of Group A and B(P<0.05). There was statistical difference in contrast sensitivity at four spatial frequencies(3, 6, 12, 18c/d)in light and light glare and three spatial frequencies(3, 6, 12c/d)in dark and dark glare in 3 groups(P<0.05), and those in the Group A were significantly better than those of Group B and C(P<0.05). According to the defocus testing of 3 groups, the visual acuity at -1.5D, -2.0D and -2.5D in Group A and B was significantly higher than Group C(P<0.05). There was statistical difference in contrast visual acuity at 20% and 9% of contrast ratio in 3 groups(P<0.05), and those in Group A were significantly better than Group B and C(P<0.05). There was statistical difference in visual quality satisfaction in 3 groups(P<0.05), and that in the Group A was significantly better than that of Group B and C(P<0.05).

CONCLUSION:The region refraction MIOL SBL-3 not only could provide better distant, intermediate and near visual acuity, but also could provide better contrast sensitivity and contrast visual acuity, thereby greatly increase visual quality satisfaction.
