AIM: To investigate the long-term clinical manifestations of Array multifocal intraocular lens implantation.

METHODS: Of 33 cases with phacoemulsification cataract operation, 19 cases(25 eyes)underwent implantation of multifocal intraocular lens(experimental group), 14 cases(20 eyes)implanted monofocal intraocular lens(control group). Postoperative far visual acuity, intermidiate visual acuity, near visual acuity, stereo vision, off glass rate under different distances was observed.

RESULTS: The near uncorrected visual acuity ≥0.5 in experimental group were 17 eyes(68%, 17/25), and that in control group were 6 eyes(30%, 6/20), there was significant difference between two groups(P<0.05). The far uncorrected visual acuity ≥0.5 in experimental group were 23 eyes(92%, 23/25), and that in control group were 20 eyes(100%, 20/20), there was significant difference between two groups(P>0.05). Intermediate visual acuity: 40cm: scores of experimental group were 54.64±10.80, scores of control group were 47.05±6.39, there was significant difference between two groups(P<0.05). 63cm: scores of experimental group were 50.36±10.32, scores of control group were 46.50±8.32, there was no significant differences between two groups(P>0.05). 100cm: scores were 43.44±8.08 and 42.05±6.63 in experimental group and control group, with no significant difference(P>0.05). Stereo vision: 6 cases of experimental group underwent bilateral operation, stereo acuity of 6 cases was ≤60″, 6 cases of control group underwent bilateral operation, 1 case stereoacuity was ≤60″, there was significant difference between two groups(P<0.05). Wear glasses rate when reading newspaper: 6 cases of the 19 cases in experimental group need glasses, 11 cases of the 14 cases in control group need glasses, there was significant difference between two groups(P<0.05).

CONCLUSION: Array multifocal intraocular lens offered good vision in postoperation, provided good stereo vision for operators, reduced the rely on glasses postoperation, improved the quality of life for patients.
