Abstract
Objective To compare visual function of patients with cataract and high myopia after phacomulsification and multifocal intraocular lens(MIOL)implantation. Methods Forty high myopia cataract eyes undertaken phacoemulsification and IOL implantation were divided into three groups: monofocal/single-focal intraocular lens(SIOL, SENSAR, AR40e, AMO)with 20 eyes, retractive MIOL(REZOOM, NXG1,AMO)with 8 eyes and diffractive MIOL(TECNIS, ZMA00, AMO)with 12 eyes. Three months after surgery,uncorrected distant visual acuity(UCDVA), uncorrected near visual acuity(UCNVA), best corrected distant visual acuity(BCDVA)and distant corrected near visual acuity(DCNVA)were observed iTrace aberrometer test intraocular aberration and modulation transfer function(MTF)of different cycle per degree(CPD)in a 5 mm pupil. Results UCDVA and DCNVA between the three groups was statistically significant(P 0.05). Spherical aberration of intraocular between the three groups showed statistical significance(P 0.05). Difference of MTF in 5/10/15 cpd was statistically significantly(P <0.05). Conclusions Diffractive MIOL is more suitable for high myopia with cataract patients than refractive MIOL. Key words: High myopia; Intraocular lens; Multifocal; Aberration
