“…An OPD-Scan III aberrometer provided the total and intraocular high-order aberration (HOA) data, including the Strehl ratio, with a mesopic pupil under mesopic (3 cd/m2) lighting conditions [11]. The OPD-Scan III provides a complete set of maps, including four different corneal topography maps, local refractive power of the entire eye due to aberrations at various locations within the pupil, a variety of wavefront aberration maps, and photopic and mesopic pupillometry.…”

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.

“…Wavefront data are gathered from available zones up to a 9.5 mm area including 2,520 data point analyses, in 7 zone measurement, adding the capability to provide for the calculation of mesopic refractions. Placido disc topography measures 33 rings in a vertical position and 39 in the horizontal position, including 11,880 data points [11].…”

“…Misalignment of the intraocular lens (IOL) is an important risk factor for the deterioration of visual quality after cataract surgery. Previous studies have found that an IOL tilt greater than 7° or decentration greater than 0.4 mm affects visual quality after IOL implantation by increasing wavefront aberrations, such as astigmatism and high-order aberrations (HOA) (1)(2)(3). Especially for toric and multifocal IOLs, their optical performances were more sensitive to tilt and decentration.…”

Background: To identify the main determinants of intraocular lens (IOL) tilt and decentration after cataract surgery using a novel anterior segment optical coherence tomography (AS-OCT) method.Methods: Fifty-six patients who underwent phacoemulsification with IOL implantation in one eye were continuously enrolled in this cohort study. Axial length (AL) was measured with IOL Master 700. The tilt and decentration of patients' preoperative crystalline lenses and postoperative IOLs, as well as crystalline lens thickness (LT), were measured using AS-OCT before surgery and 1 week after surgery. Results:The mean tilt and decentration of the patients' preoperative crystalline lenses were 4.90°±1.81° and 0.21±0.02 mm, and the mean tilt and decentration of IOLs were 4.75°±1.66° and 0.21±0.02 mm, respectively. There were no significant differences in magnitude, direction of tilt, or decentration between crystalline lenses and IOLs. The strongest determinant of IOL tilt was preoperative crystalline lens tilt (R²=0.512, P<0.001), followed by AL (R²=0.154, P=0.003). Additionally, crystalline lens decentration and AL explained 54.6% of the variability in IOL decentration. AL was the factor most highly associated with IOL decentration (R 2 =0.332, P<0.001), rather than crystalline lens decentration (R 2 =0.214, P<0.001). Conclusions:The position of the preoperative crystalline lens and AL were the critical determinants of IOL tilt and decentration. The tilt and decentration of IOLs will be greater in patients with larger tilt and decentration of crystalline lenses, or shorter and longer AL.

“…evaluated the clinical effect of misalignments in multifocal IOLs. 12,[20][21][22] Probably, centration or tilting of all IOLs with complex designs would affect both AR and MR. Thus, it would be interesting to analyze if misalignments significantly affect the AR and MR with trifocals and if the effect becomes more dramatic with trifocal toric IOLs.…”

Background: To analyze the correlation between automated refraction and manifest refraction after implantation of a trifocal intraocular lens or its toric version. Methods: This cross-sectional study involved 105 eyes of 105 patients. Subjects were divided in two groups: 62 with trifocal (AcrySof PanOptix) and 43 with trifocal toric (AcrySof PanOptix Toric) intraocular lenses. Automated refraction was employed as starting point for obtaining the manifest refraction. Automated refraction and manifest refraction measurements were analyzed and compared using the vector analysis 3 months after the surgery. Results: In both groups, the higher differences between automated refraction and manifest refraction measurements were found for the cylinder and the spherical equivalent (M). Cylinder values for PanOptix were: −0.60 ± 0.36 D with automated refraction and −0.17 ± 38 D with manifest refraction ( p < 0.001); for PanOptix Toric, the values were: −0.49 ± 0.31 D with automated refraction and −0.05 ± 0.21 D with manifest refraction ( p < 0.001). M values for PanOptix were: −0.23 ± 0.31 D with automated refraction and −0.03 ± 0.16 D with manifest refraction ( p < 0.001); for PanOptix Toric, the values were: −0.13 ± 0.40 D with automated refraction and 0.01 ± 0.12 D with manifest refraction ( p < 0.001). For the PanOptix group, intraclass correlation coefficients were: 0.51 (sphere), 0.64 (cylinder), 0.42 (M), 0.62 (J0), and 0.37 (J45). For the PanOptix Toric group, the intraclass correlation coefficients were: 0.39 (sphere), 0.61 (cylinder), 0.39 (M), 0.53 (J0), and 0.09 (J45). Conclusion: The results of this study suggest that patients implanted with the trifocal and the trifocal toric intraocular lens under study showed similar automated refraction results between them, with a slight trend to more negative amounts of cylinder and M. Nevertheless, clinicians should carefully confirm all parameters of the refraction with manifest refraction.

Comparison of long-term decentration and tilt in two types of multifocal intraocular lenses with OPD-Scan III aberrometer

Abstract: Both MfIOLs significantly improve the visual acuity of the patients. However, tilt was lower in the SN6AD1 group than in the ZMB00 group 1 year after surgery, which provide fewer HOAs and better visual quality.
