Abstract:AIM: To compare the clinical outcomes after implantation of toric multifocal and monofocal intraocular lens(IOL)after phacoemulsification.
METHODS: A total 34 patients(40 eyes)were recruited for this study. All the patients were diagnosed as age-related cataract and implanted toric multifocal or monofocal IOL after phacoemulsification. All the patients were divided into two groups: patients in group A were implanted with Acrysof IQ Toric ReSTOR+3D IOL(18 cases, 20 eyes); those in group B received Acrysof IQ Toric IOL implantation(16 cases, 20 eyes). The uncorrected and best corrected distance visual acuity(UCDVA and BCDVA), uncorrected and best corrected near visual acuity(UCNVA and BCNVA), residual astigmatism 1, 6mo postoperative and contrast sensitivity with and without glare was measured 6mo postoperative.
RESULTS: There were no statistically significant differences in UCDVA, BCDVA and DCNVA(P>0.05), but UCNVA was statistically significant difference between the two groups at 1 and 6mo after surgery(P<0.05); At 1mo after surgery, the whole residual astigmatism in group A was 0.65±0.25D, while 0.52±0.27D in group B, and no significant difference was found between the two groups(P>0.05). The same result was also found at 6mo postoperative 0.54±0.23D vs 0.40±0.20D(P>0.05). After 6mo, contrast sensitivity with and without glare were significant differences between the two groups at high spatial frequencies(P>0.05).
CONCLUSION: Acrysof IQ Toric ReSTOR+3D IOL provides better distance and near vision for cataract patients with greater corneal astigmatism and obviously improves visual quality at the early postoperative period.
