Abstract
Prospective, randomized, comparative, and controlled study to estimate the association between angle κ distance and higher-order aberrations (HOAs) with postoperative visual acuity after presbyopia-correcting IOL implantation. Forty-three eyes from 43 patients were included and randomly assigned in two groups for either AT LISA tri 839MP or Acrysof IQ PanOptix IOL implantation. The OPD-Scan III analyzer was utilized to assess the angle κ distance and higher-order aberration (HOAs). Twenty-three eyes were in the Acrysof IQ PanOptix group and 20 patients in the AT LISA tri 839MP group. The uncorrected distance visual acuity (UDVA) for the PanOptix group was 0.092 ± 0.10, whereas for AT LISA tri was 0.050 ± 0.06 (P=0.229). The uncorrected intermediate visual acuity (UIVA) for the PanOptix group was 0.173 ± 0.18, whereas for AT LISA tri, it was 0.182 ± 0.11 (P=0.669). Uncorrected near visual acuity (UNVA) was 0.068 ± 0.04 and 0.085 ± 0.07, respectively (P=0.221). Also, correlation coefficient between HOAs and the Strehl ratio for each group were −0.768 (P < 0.0001) and −0.863 (P=0.0001). Patients implanted with both trifocal IOLs showed excellent postoperative visual performance at all distances at the six-month follow-up visit. No association was found between angle κ distance and postoperative visual acuity regardless of the angle κ magnitude or the two trifocal IOLs inner optical diameter. Also, internal aberrations demonstrated a significant inverse correlation with the Strehl ratio for both trifocal IOLs.
Highlights
Trifocal intraocular lens implantation has become an ever more common solution for cataract patients who pursuit a spectacle-free option after IOL surgery [1]
A functional deviation between the optical center, the visual axis, and the pupillary axis of the multifocal IOL can lead to higher-order aberrations postoperatively, resulting in decreased visual quality. erefore, some propose including the measurement of angle kappa (κ) and angle alpha (α) in preoperative examinations of eyes Journal of Ophthalmology
Preoperative exclusion criteria for the study included corneal astigmatism over 1.0 D, ocular pathologies such as amblyopia, dry eye disease, evidence for corneal dystrophy, retinal pathology, glaucoma, and previous ocular surgery. e study comprised a total of 43 eyes from 43 patients: twenty-three eyes in the Acrysof IQ PanOptix group and twenty patients in the AT LISA tri 839MP group
Summary
Trifocal intraocular lens implantation has become an ever more common solution for cataract patients who pursuit a spectacle-free option after IOL surgery [1]. A functional deviation between the optical center, the visual axis, and the pupillary axis of the multifocal IOL can lead to higher-order aberrations postoperatively, resulting in decreased visual quality. Recognition of the importance of angle κ and angle α for successful multifocal IOL implantation is growing, there are little data regarding their impact on objective visual quality. Acknowledgment of the importance of angle κ for successful multifocal IOL implantation is increasing, few data regarding their impact on objective visual quality is widely available. E purpose of the present study was to estimate the association between angle κ distance and higher-order aberrations (HOAs) with postoperative visual acuity and vision quality after presbyopia-correcting IOL implantation employing either AT LISA tri 839MP or Acrysof IQ PanOptix IOL
