“…In addition to the wavefront aberration, the double-pass system was used to assess the objective visual function. There are studies that used this system for assessing the correlation between optical quality and decentration after Orthokeratology [28] and toric IOL implantation [29]. In the current study, we found no significant association between decentration and postoperative MTF cutoff, OSI, SR, and OVs in either group.…”

Background To measure the decentration following SMILE in eyes with high myopic astigmatism and investigate its impact on visual quality. Methods The prospective study was conducted to analyze patients who underwent SMILE for correction of myopia and myopic astigmatism ≥2.5D (high astigmatism group, HA) at the ophthalmology department, Eye and ENT hospital, Shanghai, China.. Patients with myopic astigmatism < 1.5D served as controls (low astigmatism group, LA). Decentration was measured using a Scheimpflug camera with a difference map of the tangential curvature at 12 months postoperatively. Also the associations between decentration from the coaxial sighted corneal light reflex (CSCLR) and the visual outcomes, correction efficacy of astigmatism, wavefront aberrations and objective scatter index (OSI) were analyzed. Results No significant differences were observed in the decentered distance between HA and LA in either eyes (OD: HA: 0.18 ± 0.10 mm, LA: 0.20 ± 0.14 mm, P = 0.659; OS: HA: 0.22 ± 0.11 mm, LA: 0.20 ± 0.11 mm, P = 0.637). The analysis across the three levels of decentration (< 0.1 mm, 0.1–0.2 mm, and > 0.2 mm) showed no significant association between decentration and visual outcomes of predictability, efficiency, safety, MTF cutoff, OSI, SR and OVs in both groups. Also no significant association was observed between decentration and postoperative astigmatism in either group. A significant relationship between the magnitude of decentration and induced coma and spherical aberration was observed in HA. Conclusions The amount of decentration between HA and LA groups showed no differences. Decentration > 0.20 mm from CSCLR resulted in greater induction of coma and SA after SMILE in eyes with HA.

“…In this study, we found a significant difference between preoperative and postoperative optical quality. e respective mean postoperative MTF cutoff and OSI values were 21.79 ± 10.62 and 3.13 ± 3.17. e postoperative MTF cutoff value was comparable with that in previous studies, whereas the OSI value was relatively high; the optical quality after toric IOL implantation appeared to be slightly worse in our study [44,45]. e OSI value was <3 in 17 eyes (74%), and there was one abnormal value of 15.8 in an eye with central corneal scarring and opacity, which underscores the powerful impact on the OSI.…”

Purpose. To evaluate visual acuity (VA) and refractive status in patients with cataract and irregular astigmatism with a regular central component after phacoemulsification with implantation of a toric intraocular lens (IOL). Methods. Patients with cataract associated with irregular astigmatism with a regular central component were enrolled. All patients underwent phacoemulsification and toric IOL implantation. Postoperative visual acuity, residual astigmatism, toric IOL rotation, higher-order aberration, and objective and subjective visual quality were measured 3 months after surgery. Results. Twenty-three eyes were included in the study. The logMAR corrected and uncorrected distance visual acuity values were decreased at 3 months postoperatively (p < 0.005). The preoperative average corneal astigmatism and postoperative residual astigmatism were 1.15–6.97 D (1.99 ± 1.26 D) and 0–2.75 D (0.65 ± 0.57 D), respectively. The average IOL rotation was 3.17 ± 2.01°. Some objective indicators of visual quality, including the modulation transfer function (p < 0.05), Strehl ratio (p < 0.005), 100% VA (p < 0.005), 20% VA (p < 0.005), and 9% VA (p < 0.005), were significantly higher than the corresponding preoperative values. The objective scatter index (p < 0.005) was significantly lower than that before surgery. The postoperative VF-14 scale score was 83.99 ± 14.58. Conclusion. Toric IOL implantation has a good corrective effect on certain specific types of corneal irregular astigmatism with cataract. This effect can be attributed to its ability to correct the regular component of irregular astigmatism. The indications for toric IOL implantation could be expanded to some extent, thereby bringing benefit to more patients.
