ABSTRACT
@#AIM: To contrast the visual acuity and visual quality after implantation of regional refraction multifocal IOL and aspheric unifocal IOL.<p>METHODS: The study enrolled 82 cases(96 eyes)of age-related cataract patients, underwent phacoemulsification surgery in our hospital. According to the intraoperative intraocular lens implantation type, they were divided into two groups: the observation group(46 cases, 53 eyes, implanted with Oculentis MF30 regional refractive multifocal IOL)and the control group(36 cases, 43 eyes, implanted with ADAPT AO aspherical unifocal IOL). The total visual acuity and visual quality 3mo after operation were compared between the two groups. <p>RESULTS: Three months after surgery, compared with the control group, the observation group had significantly improved near and middle vision, significantly increased contrast sensitivity, significantly increased modulation transfer function cutoff frequency, Strehl ratio, objective scatter index and OQAS values, significantly decreased VF-12-CN score(38.16±4.05 <i>vs</i> 45.72±4.69), and significantly increased desorption rate score(11.38±1.04 <i>vs</i> 9.23±0.87)and surgical satisfaction score(3.57±0.36 <i>vs</i> 3.32±0.31)(<i>P</i><0.05). Age >65 years old, illiteracy, uncorrected distant visual acuity of good eye ≥0.1(LogMAR), implantation of aspheric unifocal IOL are the influencing factors of the quality of life of cataract patients. <p>CONCLUSION: Compared with aspheric unifocal IOL, Oculentis regional refraction multifocal IOL can provide good overall vision in the short term after operation, and the contrast sensitivity, visual quality, quality of life, glasses removal rate and satisfaction are significantly improved.
