Comparison of clinical efficacy between new infinite and multifocal lens implantation in the treatment of cataract combined with astigmatism and presbyopia
Aim To compare the effection of Tecnis Symfony and multifocal lens implantation in phacoemulsification for cat-aract patients with astigmatism and presbyopia.Methods 103 patients(115 eyes)with cataract,astigmatism and presbyopia who underwent phacoemulsification were divided into Tecnis Symfony group(n=54,62 eyes)and multifocal group(n=49,53 eyes).The two groups were compared on vision,postoperative contrast sensitivity,whole eye wavefront aberration,postoperative satisfaction,spectacles-independent rate,poor vision,and postoperative complications.Results Vision of both groups was improved after op-eration(P<0.05).After operation,the Tecnis Symfony group had lower near vision and higher middle vision than the multifocal group(P<0.05).Compared with the multifocal group,the Tecnis Symfony group had higher sensitivity under different spatial fre-quencies in dark environment(P<0.05).The total aberrations,total high-order aberrations,trefoil,coma and other whole-eye wavefront aberrations in the Tecnis Symfony group were lower than in the multifocal group(P<0.05).Satisfaction score of near vi-sion of the Tecnis Symfony group was lower,and the satisfaction scores for smooth reading under middle vision and night vision were higher than in the multifocal group(P<0.05).The incidence rates of astral sensation,halos around lights,and glare in the Tecnis Symfony group were lower than in the multifocal group(P<0.05).There is no significant difference in the comparison of complica-tions between the two groups(P>0.05).Conclusion Applying Tecnis Symfony and multifocal lens both can effectively improve vision of cataract patients with astigmatism and presbyopia.However,the former has more advantages in improving middle vision,and the latter has more advantages in improving near vision.
