| 6 | Optic nerve compression:the role of the lamina cribrosa and translaminar pressure显示文摘AIM: To evaluate the impact of spherical and aspherical intraocular lenses on the postoperative visual quality of age-related cataract patients using Optical Quality Analysis System(OQAS).METHODS: Seventy-four eyes with age-related cataracts were randomly divided into spherical and aspherical lens implantation groups. Best-corrected visual acuity(BCVA) was measured preoperatively, one day, one week, two weeks, one month and two months after surgery. A biometric systems analysis using the OQAS objective scattering index(OSI) was performed. RESULTS: There were no significant differences in visual acuity(P>0.05) before and after spherical and aspheric lens implantation. There was a negative linear correction between the OSI value and BCVA(r=-0.634, P=0.000), and positive corrections between the OSI value and the lens LOCUS III value of nucleus color(NC), nucleus opacity(NO), cortex(C) and posterior lens capsular(P)(r=0.704, P=0.000; r=0.514, P=0.000; r=0.276, P=0.020; r=0.417, P=0.000, respectively). OSI values of spherical vs aspherical lenses were 11.5±3.6 vs 11.8±3.4, 4.1±0.9 vs 3.3±0.8, 3.5±0.9 vs 2.7±0.7, 3.3±0.8 vs 2.6±0.7, 3.2±0.7 vs 2.5±0.8, and 3.2±0.8 vs 2.5±0.8 before and 1d, 1, 2wk, 1 and 2mo after surgery, respectively. All time points varied significantly(P<0.01) between the two groups.CONCLUSION: Aspherical IOLs does not significantly affect visual acuity compared with spherical IOLs. The OSI value, was significantly lower in the aspherical lens group compared with the spherical lens. This study shows that objective visual quality of aspheric IOLs is better than that of the spherical lens by means of OQAS biological measurement method. | mario r romano gilda cennamo maria angelica breve michela piedepalumbo claudio iovino nunzio velotti giovanni cennamo | 2017 | International Journal of Ophthalmology(English edition)2017，10，12： | 0 |
