| description | AIM: To investigate the correlation between postoperative lens decentration and tilt and visual quality in eyes implanted with aspherical intraocular lens(IOL)by using a new anterior segment swept-source optical coherence tomography(OCT)CASIA2.METHODS: An observational study. A total of 90 eyes of 62 participants who underwent age-related cataract surgery at 1mo were included. Using CASIA2 by an experienced examiner, IOL tilt and decentration were obtained three consecutive times after mydriasis and the vector mean values were calculated. Double-pass optical quality analysis system(OQAS)and wavefront aberration instrument KR-1W were used for the visual quality measurements, including the total high-order aberration(tHOA), spherical aberration(SA), Coma, objective scatter index(OSI), modulation transfer function cut off frequency(MTF cut off)and Strehl ratio(SR)at 4 and 6mm pupil diameter.RESULTS: IOL decentration was positively correlated with SA(r=0.347, P=0.001)and OSI(r=0.343, P=0.002)at 4mm pupil diameter, and it was negatively correlated with MTF cut off(r=-0.244, P=0.032). There was no significant correlation between IOL decentration and tHOA, Coma and SR. IOL tilt was negatively correlated with MTF cut off(r=0.-345, P=0.002)and SR(r=-0.256, P=0.023)at 4mm pupil diameter, but it was not correlated with tHOA, SA, Coma and OSI. There were no significant correlations between the IOL decentration and tilt and tHOA, SA, Coma, MTF cut off and SR at 6mm pupil diameter.CONCLUSION: After aspherical IOL implantation in age-related cataract patients, IOL decentration was weakly correlated with SA at 4mm pupil diameter, while decentration and tilt were not significantly correlated with other higher-order aberrations. The decentration and tilt were weakly correlated with OSI value and MTF cut off value of the visual quality parameters. The results suggest that clinicians should pay more attention to higher-order aberrations and visual quality during precise cataract surgery. |
