Comparative analysis of visual function between Tecnis Symfony intraocular lens and monofocal aspheric intraocular lens implantation
Abstract
Objective To compare and analyze the visual function of cataract patients after Tecnis Symfony intraocular lens (IOL) and monofocal aspheric IOL implantation. Methods Fifty cataract patients admitted to our hospital from October 2023 to December 2024 were selected and divided into experimental group (Tecnis Symfony IOL implanted，25 cases) and control group (Tecnis ZCB00 IOL implanted,25 case) according to the type of lens implanted. Postoperative vision, adjustment range, simultaneous viewing and fusing functions, far and near stereovision, Visual function satisfaction questionnaire survey, de-lens rate, defocus curve, contrast sensitivity. Results There was no significant difference in uncorrected visual acuity between the two groups at a distance of 5 m (P>0.05), but the visual acuity of the experimental group at a distance of 63 cm and 30 cm was significantly better than that of the control group (P<0.05).The accommodation amplitudes of right eye, left eye and both eyesin the experimental group were significantly better than those in the control group (P<0.05). There was no significant difference between the two groups in the number of patients with simultaneous visual function and fusion function (P>0.05). There was no significant difference in distance stereoscopic vision between the two groups (P>0.05), and the near stereovision of the experimental group was better than that of the control group (P<0.05). There were no patients with distance vision difficulties in both groups, and there was no significant difference in the number of patients with uncomfortable symptoms such as night glare between the two groups (P>0.05). Compared with the experimental group, the number of patients with difficulty in medium and near vision was significantly higher in the control group (P<0.05).The lens removal rate in the experimental group was significantly higher than that in the control group (P> 0.05).There were no significant differences in defocus curves and contrast sensitivity values between the two groups (P>0.05). Conclusion Tecnis Symfony IOL can better improve most visual functions of cataract patients than Tecnis ZCB00 IOL, but some aspects of visual function improvement still need to be optimized.
