The Clinical Analysis Of Different Intraocular Lens Implantation For Cataract With High Myopia

Chapter I The clinical analysis of three kinds of intraocular lens implantation for cataract with high myopiaObjective:Comparsion clinical effects of high myopia cataract patients were implanted three different kinds of intraocular lenses (IOLs)Methods:Sixty-eight high myopia cataract eyes undertaken phacoemulsification and IOLs implantation, including three different kinds of IOLs.1-piece hydrophilic acrylic IOLs (Bigbag, ZEISS); 1-piece hydrophilic acrylic IOLs (620H, Rayner); and 1-piece hydrophilic acrylic IOLs (HQ201-hep).Anterior chamber depth after mydriasis, tilt and deviation of IOLs were measured using Scheimpflug system (Pentacam, Oculus) and analyzed with Image-pro plus 6.0 software. iTrace aberrometer test intraocular spherical aberration in a 5mm pupil.Results:Comparison of the anterior chamber deepth between the three groups was statistically significantly (F=50.74, P<0.05). Difference between actual refraction of postoperation and target refraction was not statistically significant (F=1.391, P>0.05).Deviation and tilt of IOLs between the three groups showed no statistical significance (P>0.05). Spherical aberration of intraocular between the three groups showed no statistical significance(F=2.096, P>0.05).No eyes were detected posterior capsule opacification, no macula edema and retinal detachment. Conclusions:Three different kinds of IOLs can be implanted for cataract patients with high myopia, but each has its advantages and limitations.Chapterâ…¡Comparison visual quality between different multifocal IOLs in cataract patients with high myopiaObjective:Comparison 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:mono focal/single-focal intraocular lens (SIOL, SENSAR, AR40e, AMO) with 20 eyes, refractive MIOL (REZOOM, NXG1, AMO)with 8 eyes and diffractive MIOL (TECNIS, ZMA00, AMO) with 12 eyes.3mo 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 5mm pupil.Results:UCDVA and DCNVA between the three groups was statistically significantly (P<0.05). BCDVA and UCNVA between the three groups was not statistically significant (P>0.05).Spherical aberration of intraocular between the three groups showed statistical significance (P<0.05). Other aberration of intraocular between the three groups showed no 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.
