Clinical study inpatient-reported outcomes after binocular implantation of aspheric intraocular lens of different negative spherical aberrations

To compare patient-reported outcomes after implantation of the ZA9003 intraocular lens (IOLs), or the MCX11 ASP IOLs or the spherical IOLs (HQ-201HEP).

Prospective nonrandomized controlled trial was used. A total of 105 patients (210 eyes) were divided into three groups according to the type of IOLs: ZA9003 (35 patients, 70 eyes), MCX11 ASP (35 patients, 70 eyes) or HQ-201HEP (35 patients, 70 eyes). The main outcome was scores of Catquest nine-item short-form questionnaire. Additional outcome was best corrected visual acuities, spherical aberration (SA) and total higher-order aberrations (HOAs).

The global score was significantly lower in the spherical IOL group than the aspherical IOL group of -020 μm SA (P < 0.05) and the aspherical IOL group of -027 μm SA (P < 0.05), and no significant difference was found in the global score between the aspherical IOL group of -020 μm SA than the aspherical IOL group of -027 μm SA (P > 0.05). Significant differences were also found in question 2, question 5, question 6 and question 8 between the spherical IOLs and the aspherical IOLs.

Implantation of an aspherical IOL could improve vision-related quality of life compared with a spherical IOL. However, there were no statistically significant differences in vision-related quality of life between aspheric IOLs with different negative spherical aberrations.
