Postoperative assessments (1 day and 1, 3, and 6 months) included uncorrected and corrected distance visual acuity (UDVA/CDVA), area of continuous curvilinear capsulorhexis (ACCC), IOL tilt/decentration, intraocular pressure (IOP), and corneal endothelial cell (CEC) counts.Results: All groups had improved UDVA/CDVA postoperatively (P > .05). At 3 and 6 months, horizontal IOL tilt/decentration differed significantly among groups (P < .05). The control group had greater tilt at 3 and 6 months versus 1 week (P < .05) and the small group at 3 months versus 1 week (P < .05). All groups had lower ACCC at 6 months versus baseline (P < .05). The large group had the highest posterior capsule-IOL attachment rate (85%) and the lowest posterior capsular opacity rate (5% vs 12.5% in the small group and 22.5% in the control group). Postoperative IOP/CEC showed no intergroup differences (P > .05).Conclusions: In eyes with AL of 30 mm of greater, the CTR1311 more fully supports the lens sac, reduces its shrinkage, stabilizes the IOL, and thus obtains better visual quality. However, the study had limited power (61%) due to the smaller sample size. Therefore, although selecting a large CTR in such patients is recommended based on our findings, further validation in larger studies is warranted.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 3","pages":"e198-e207"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147372806","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}

Preoperative assessments included optical biometry with the IOLMaster 700 (Carl Zeiss Meditec AG) and anterior segment optical coherence tomography (AS-OCT) with the MS-39. IOL power was calculated with 7 formulas (Barrett Universal II, EVO 2.0, Haigis, Hoffer QST, Holladay 1, Kane, and SRK/T) using both the measured preoperative keratometry and an estimated postoperative keratometry derived from a regression model (ΔK = 5.281 + 1.926 × Rant - 1.493 × Rpost). The spherical equivalent prediction error (SEQ-PE) was assessed at 6 months and analyzed using Eyetemis.Results: Substituting the estimated keratometry for the measured keratometry halved the hyperopic SEQ-PE across all formulas (from > +1.00 D to approximately +0.50 D), improving both trueness and overall accuracy. Although precision (ie, standard deviation) also improved, this change was not statistically significant. The formulas achieving the highest percentage of eyes with SEQ-PE less than ±0.50 D were Haigis and EVO 2.0 (52% each), followed by Hoffer QST (48%).Conclusions: Using estimated keratometry values derived from a regression model significantly improves refractive outcomes in patients with FED undergoing triple DMEK, reducing the risk of hyperopic surprises following surgery.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 3","pages":"e257-e263"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147372953","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}

Primary outcomes (capsular bend index [CBI], adhesion index [AI], and continuous curvilinear capsulorhexis diameter [CCCD]) and secondary outcomes (IOL tilt and decentration) were quantitatively assessed at 1 week, 1 month, and 3 months postoperatively using 14-meridian swept-source optical coherence tomography (SS-OCT) (CASIA 2; Tomey). Additional secondary outcomes were root mean square (RMS), corrected distance visual acuity (CDVA), and spherical equivalent refraction (SER).Results: Forty-five eyes were enrolled (23 ACP, 22 control), and 40 (20 per group) completed a 3-month follow-up. At 3 months, the ACP group showed lower CBI (3.16 vs 3.68; P = .001) and AI (0.00 vs 0.32; P = .023), larger CCCD (5.30 vs 5.04 mm; P = .025), and less CCCD contraction (0.11 vs 0.22 mm; P = .034). Between-visit changes in CBI and AI did not differ between groups. Vertical tilt and its RMS were greater with ACP (P = .012 and .009, respectively), whereas horizontal tilt, decentration, CDVA, and SER were comparable.Conclusions: ACP slows early C-IOL structural maturation (reduced capsular-bend kinetics and delayed capsule-IOL adhesion) without compromising early refractive stability and stabilizes the capsulorhexis, but increases vertical IOL tilt. These findings support selective use in eyes prone to contraction and caution when precise IOL alignment is required.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 3","pages":"e264-e272"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147372727","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}

Preoperative and postoperative visual quality was assessed using the Objective Scatter Index (OSI). High-precision segmentation of posterior lenticule scanning images was performed using a U-net-based deep learning model to extract radiomics features. These features, along with clinical data, surgical parameters, corneal topography, and biomechanics, were integrated into machine learning models for predicting OSI at 1 day and 1 week postoperatively.Results: The study found that 30.95% (65/210) of eyes experienced poor early visual recovery. Significant differences in spherical equivalent, corneal curvature, and cutting depth were observed between good and poor visual quality groups. The ExtraTrees model demonstrated high efficacy in predicting OSI on the first postoperative day (area under the curve [AUC] = 0.96), whereas the AdaBoost model excelled at 1 week (AUC = 0.99). Regression models RidgeCV and LassoLarsIC performed best for predicting OSI values at 1 day and 1 week, respectively. Radiomics features such as original topology Gaussian Curvature Min and original gldm Dependence Variance were significantly correlated with the OSI.Conclusions: The study establishes a predictive framework that integrates intraoperative scanning image features, corneal biomechanics, and densitometry parameters, offering a quantitative basis for personalized surgical planning. The synergistic use of radiomics and clinical parameters can pre-identify high-risk patients, optimize surgical settings, and improve postoperative visual quality.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 3","pages":"e235-e247"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147372795","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}

Texture features through radiomics were extracted from CVS images acquired at three key deformation phases: initial state, first applanation, and maximum deformation. These features were used to train three machine learning models (Random Forest [Minitab, Inc], C5.0 [RuleQuest Research], and XGBoost (extreme Gradient Boosting) on 328 eyes, with testing conducted on 82 eyes. Diagnostic performance was evaluated using receiver operating characteristic (ROC) analysis and compared with conventional biomechanical parameters.Results: The CVS-omics Random Forest model achieved superior diagnostic performance (area under the curve (AUC) = 0.989, sensitivity = 0.931, specificity = 0.962, accuracy = 0.951), significantly outperforming traditional CVS parameters (best AUC = 0.764). Models trained on features from three deformation phases showed higher diagnostic accuracy than those based on a single phase. Other models demonstrated high generalizability of dynamic radiomics features (XGBoost and C5.0 AUC > 0.83).Conclusions: CVS-omics effectively detects subtle characteristic alterations in FFKC eyes with superior accuracy compared to conventional biomechanical parameters.

Review of the literature revealed only two other published cases describing infectious keratitis following FLACS-AK.Results: All patients underwent uneventful FLACS-AK in both eyes and later developed unilateral infectious keratitis at the arcuate keratotomy incision. One patient developed an early-onset, fulminant infection with cultures positive for Pseudomonas aeruginosa. Two patients presented with late-onset, milder infections, with negative culture results. Two patients developed a very late-onset infection due to P. aeruginosa, with one of them requiring surgical intervention. All patients were also treated with fortified antibiotics. Four of five patients had good clinical and visual outcomes, whereas one patient suffered from devastating results.Conclusions: Infectious keratitis following FLACS-AK is a rare but potentially sight-threatening complication with variable onset and severity. Penetrating arcuate keratotomies may pose a higher risk of infection compared to intrastromal incisions, underscoring the need for careful surgical planning and long-term postoperative surveillance. Surgeons should therefore consider performing an intrastromal incision or, when applicable, a different method for arcuate correction.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 2","pages":"e189-e195"},"PeriodicalIF":3.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146149940","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}
