Four of each were assessed under light microscopy (n = 20), and two were assessed under scanning electron microscopy (n = 10). A qualitative evaluation of all samples was conducted, as well as a semi-quantitative analysis of the extent of irregularities present in light microscopy samples. Dunn's multiple comparisons test was conducted to determine which lasers produced significantly smoother capsulotomies.Results: Irregularities along the lens capsule rim were observed in all samples. Distinct irregularities were observed for Catalys (unconnected laser pulses bordering the capsulotomy), FEMTO LDV Z8 (numerous additional rows of laser pulses), and LensAR (at least one section with multiple rows of laser pulses). Victus demonstrated a significantly higher degree of smoothness of capsulotomy (median = 306°) compared to Catalys (median = 171°) (P = 0.02). The medians for other laser platforms fell between these values.Conclusions: Different laser platforms produce morphologically and quantitatively distinct irregularities, which may influence capsulotomy strength differently. FEMTO LDV Z8, a low-energy laser, did not produce a smoother capsulotomy than the high-energy lasers. Our results suggest that, with current technologies, the precision of the laser is more important than the pulse energy in determining the regularity of the capsulotomy surface.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144846633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used ray-tracing simulations to assess the dependency of add-power demand on ocular biometry.Setting: David J. Apple Laboratory for Ocular Pathology.Design: Experimental study.Methods: Optical biometry of 34 patients scheduled for routine cataract surgery was collected and the following parameters used to build a personalized eye model: keratometry (K), anterior chamber depth (ACD), and axial length (AL). Ray-tracing software was applied for pseudophakic-eye simulations. Each model featured a biconvex lens with radii of curvature adjusted for best distance-vision. Trial glasses with -4D, -3D, -2D, and -1.5D were placed in front of a virtual eye. The IOL-power change required to induce a desirable near/intermediate effect at the spectacle plane was calculated with respect to the far-point condition.Results: Mean values for K, ACD, and AL were 7.79±0.24mm, 3.22±0.60mm, and 23.77±1.34mm, respectively. The lowest and highest add power (IOL plane) varied by 0.39D, 0.52D, 0.76D, 0.98D for -1.5D, -2D, -3D and -4D trial glasses, respectively. High correlation was found between the observed add-power change and the ACD, indicating a linear increase of the add-power demand for larger ACD values. The AL and the K demonstrated poor or no correlation with the required IOL-power adjustment.Conclusions: The ACD, which determines the effective lens position in our model, has greater impact on add-power demand than AL or K. The reported change may contribute to inter-subject variability in defocus curves of multifocal patients.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144846634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with previous ocular surgery or pathologies that would affect visual outcomes were excluded. The parameters evaluated were uncorrected and corrected visual acuity, subjective refraction, efficacy and safety index, predictability, endothelial cell density, central vault, and postoperative complications. One hundred seven eyes from 67 patients in group 1 and 289 eyes from 164 patients in group 2 were evaluated.Results: At 5 years, the safety and efficacy index were similar (p=0.224 and p=0.390, respectively).

UBM was used to measure the ciliary sulcus to sulcus (STS), central distance from endothelium to STS (ASL) crystalline lens to STS (STSL), the angle to angle distance (ATA) and ACD to crystalline lens (ACD-L) in both the horizontal and vertical orientations.

The opacification was assessed via slit lamp examination and optical coherence tomography (OCT). Its impact on visual acuity (VA), far contrast sensitivity (CS) and near vision satisfaction using the NAVQ10 questionnaire.Results: The mean time to IOL opacification development was 56.4±24.0 months. The most common opacification patterns were total diffuse (44.1%), peripheral plaque (33.9%) and miscellaneous (8.5%). Both uncorrected and corrected distance and near VA significantly worsened upon detection of IOL opacification (p<0.001). Mean CS values for 6, 12 and 18 cycles/º fell outside the range of normality. Fewer than 8% of patients reported extreme difficulties performing near vision tasks. OCT measurements revealed mean maximum and minimum opacification thicknesses of 72.2±24.6 and 51.8±21.2 µm, respectively. IOL explantation was required in 8 eyes (13.6%), with significant VA improvement after IOL exchange (p<0.001). Severe postoperative complications occurred in 3 patients following explantation.Conclusions: Opacification of Lentis Mplus IOLs typically presents with a diffuse pattern, leading to deterioration in VA and CS. This complication can be managed by exchanging the opacified IOL with a fully transparent alternative; however, the surgical procedure carries inherent risks that require careful consideration.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144794564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first eye which underwent surgery was randomized.Methods: Patients of the center undergoing routine cataract surgery who enrolled in the study completed a questionnaire immediately after surgery to describe their surgical experience for each eye. Survey questions measured patient pain, discomfort or pressure, comfort, relaxation, estimated length of surgery and predicted visual outcome.Results: Patient reported level of pain during the second eye surgery was significantly greater than for the first eye (p<0.001). Furthermore, the order of surgery was found to be a strong predictor of patient reported pain (p<0.001), more so than surgical length (p<0.008), additional anesthesia (p<0.35), patient age (p<0.44) or patient sex (p<0.88). Overall, surgery during the first eye was reported as more comfortable (p<0.001) and shorter in duration (p<0.001) while discomfort and pressure were reported as worse for the second eye (p<0.001).Conclusions: Understanding differential experiences between eyes can help surgeons when counselling patients regarding expectations for ISBCS and related visual outcomes.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144784315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
