Clear lens phacoemulsification with monovision for the correction of high myopia

Abstract

Objective To explore the clinical efficacy of clear lens phacoemulsification with monovision combined with artificial lens implantation for the correction of high myopia.Methods This study included 45 patients ( 90 eyes ) diagnosed as high myopia.The distant and near visual acuity ( VA ) and the dominant eye were examined.All the eyes received binocular phacoemulsification and monofocal intraocular lens ( IOL ) implantation.Monovision correction was chosen for 28 patients ( 11 males and 17 females ).Implantation of IOL was designed to yield a spherical equivalent of -2.0～- 2.5D for the nondominant eye.Full correction was performed on 17 control subjects.Distant and near VA in both eyes and the diopter were followed up for 3 months postoperatively.Results Predicted refraction and ideal distance binocular vision were achieved in all the patients.The mean uncorrected distance binocular VA was( 0.83 ± 0.15 ) in the monovision group and ( 0.81 ± 0.13 ) in the control group ( P ＞ 0.05 ).The mean uncorrected near VA was ( 0.68 ± 0.25 ) in the monovision group and ( 0.38 ± 0.21 ) in the control group ( P ＜ 0.05 ).3 months after treatment,the rate of patients reading without glasses was 78.5％ and 20.3％,respectively ( P ＜ 0.05 ).No retinal detachment and cystoid macular edema occurred 3 months after the treatment.Conclusions Clear lens phacoemulsification with monovision is a safe and effective procedure in the corection of high myopia.The patients do not need to wear reading glasses whenever seeing far or near postoperatively.
