Abstract Background：To evaluate the effects of anterior capsular opening size on deviation from predicted refraction and the effective position of intraocular lens (ELP) in cataract surgery. Methods：Eighty patients (80 eyes) with simple age-related cataracts were treated from May 2018 to September 2018 at the Fourth Affiliated Hospital of China Medical University. The patients were divided into 2 groups : 40 eyes were implanted with the C-loop haptic intraocular lens (AMO Tecnis ZCB00) while the other 40 eyes were implanted with the plate haptic intraocular lens (CT ASPHINA 509M). Follow-up visits were conducted postoperatively at 1 week, 1 month, and 3 months during which patients underwent refraction and data collection after pupil dilation that included anterior segment photography and Scheimpflug imaging by Pentacam. The area, horizontal and vertical diameter of the capsulorrhexis, circularity, decentration, and package were analysed using the image analysis software Image-Pro-Plus 6.0 that evaluated the relationship between the different shapes of capsulorrhexis with deviation from predicted refraction and ELP in cataract surgery. Results: Deviation from predicted refraction and all of the parameters of capsulorrhexis were not correlative in the 509M IOL group, however, in the Tecnis IOL group, while the deviation from predicted refraction and all of the capsulorrhexis parameters were not correlative at 1 week, the deviation from predicted refraction did correlate with capsulorrhexis area,horizontal diameter at 1 month (P=0.029, P=0.048), and the capsulorrhexis area ,vertical diameter at 3 months (P=0.03, P=0.017).The ELP correlated with package in both groups postoperatively (r>0, P<0.05), but there is no other capsulorrhexis parameters correlate with ELP in the 509M IOL group (all P>0.05). For the Tecnis IOL group, the ELP and capsulorrhexis area were correlated at 1 week and 1 month, while the ELP and horizontal diameter, the ELP and vertical diameter were correlated at 1 week , but did not correlate with the other capsulorrhexis parameters in the Tecnis IOL group (all P>0.05). Conclusions: The shape of the capsulorrhexis has an effect on postoperative refractive outcomes and the effective position of intraocular lens in cataract surgery, and plate haptic intraocular lenses have better refractive stability than C-loop haptic intraocular lenses.（ChiCTR-TRC-1800015638）

The PanOptix® IOL used for cataract surgery showed high patient satisfaction and a high probability of spectacle independence for distance and near vision. The postoperative refractive outcomes demonstrated a low spheroequivalent and cylinder, primarily related to careful IOL measurements, advanced IOL formulas, and surgical technique.

Abstract Background: Both femtosecond laser-assisted arcuate keratotomy (FS-AK) and toric intraocular lens (IOL) implantation were effective in correction for eyes with corneal astigmatism. The objective of this study was to evaluate the postoperative refractive outcomes of patients receiving femtosecond laser-assisted cataract surgery (FLACS) with FS-AK and patients receiving standard phacoemulsification with toric intraocular lens implantation Methods: This retrospective study reviewed the postoperative outcome of patients undergoing FLACS with FS-AK (FS-AK group) and patients undergoing standard phacoemulsification with toric IOL implantation (toric IOL group). The main outcome measures were bare and corrected visual acuities, keratometric and refractive astigmatism, and vector analysis.Results: The FL-AK group included 41 eyes with preoperative keratometric astigmatism of −1.64 diopters (D) ± 0.42 (standard deviation), and the toric IOL group included 53 eyes with preoperative keratometric astigmatism of −2.29 ± 0.91 D (P < 0.001). Postoperative refractive astigmatism was comparable between the two groups. Postoperative bare vision was significantly better (P = 0.005) and corrected visual acuity was marginally better in the toric IOL group than in the FS-AK group (P = 0.051). The absolute angles of error were 9.95 ± 9.57 degrees and 5.08 ± 4.94 degrees (P = 0.02) in the FS-AK and toric IOL groups, respectively.Conclusion: Both FLACS with FS-AK and standard phacoemulsification with toric IOL implantation represent safe and effective methods for astigmatism correction at the time of cataract surgery. Standard phacoemulsification with toric IOL implantation achieves better visual outcome than combined FLACS and FS-AK at 6-month follow up.

Abstract This study aimed to determine whether inter-ocular differences in axial length (AL), corneal power (K), and adjusted emmetropic intraocular lens power (EIOLP) and inter-visit differences in these ocular biometric values, measured on different days, are related to refractive outcomes after cataract surgery. We retrospectively reviewed 279 patients who underwent phacoemulsification. Patients underwent ocular biometry twice (1–4 weeks before and on the day of surgery). Patients were divided into three groups: group S (similar inter-ocular biometry in different measurements; n = 201), group P (inter-ocular differences persisted in the second measurement; n = 37), and group D (inter-ocular difference diminished in the second measurement; n = 41). Postoperative refractive outcomes (mean absolute errors [MAEs]) were compared among the groups. Postoperative MAE2, based on second measurement with reduced inter-ocular biometry difference, was smaller than that calculated using the first measurement (MAE1) with borderline significance in group D (MAE1, 0.49 ± 0.45 diopters vs. MAE2, 0.41 ± 0.33 diopters, p = 0.062). Postoperative MAE2 was greater in group P compared to the other two groups (p = 0.034). Large inter-ocular biometry differences were associated with poor refractive outcomes after cataract surgery. These results indicate that measurements with smaller inter-ocular differences were associated with better refractive outcomes in cases with inter-visit biometry differences.
