Methods
This prospective cohort study was approved by the Institutional Review Board of the Eye and Ear, Nose, and Throat Hospital of Fudan University, Shanghai, China. All procedures adhered to the tenets of the Declaration of Helsinki. All patients provided written informed consent for their medical records to be used for research purposes. The study was registered at www.clinicaltrials.gov (accession number NCT03062085).
Results
Table 1 provides the patients' demographic data. No statistically significant between-group differences were identified for age, sex, operated eye, or preoperative visual acuity (Student t tests for age and preoperative visual acuity, χ2 tests for sex and operated eye, all P > .05). Postoperative uncorrected distance, best-corrected distance, and uncorrected near visual acuities did not differ significantly between the 2 groups (Student t tests, all P > .05). AXL was significantly longer in the
Discussion
Despite the wide application of MfIOLs, there is still uncertainty regarding their use in myopic eyes.12, 16 Many surgeons are concerned that complicated fundal conditions in myopic eyes impair MfIOL optical function.17, 18 However, few have considered IOL instability induced by incompatibility between fixed and increased sizes of IOLs and capsular bags in myopic eyes, respectively. In the current study, we used an OPD-Scan III aberrometer to evaluate the tilt and decentration of MfIOLs

2022, Journal of OptometryCitation Excerpt :In addition, other factors that may affect visual quality were not analyzed (i.e. IOL centration, kappa angle, alpha angle). Additional studies are warranted26–28. In conclusion, the trifocal intraocular lens PanOptix® showed very satisfactory results in this group of patients, who achieved independence of the glasses and expressed a high level of satisfaction.

2022, American Journal of OphthalmologyCitation Excerpt :Thus, the predictive model of AL on IOL decentration needs to be further improved and verified in longitudinal studies with a larger sample size. The existing studies on IOL tilt were mainly for emmetropic or moderately myopic eyes, and the extent and direction of tilt were measured relative to the pupillary axis, which is prone to be affected by the pupillary changes.14,24-27 In contrast, CASIA2 can provide relatively stable data of IOL tilt because the CASIA2 uses the corneal topographic axis, which is independent of pupillary changes.16
