Total postoperative clinical time, number of visits, mean visit duration, and visual outcomes were analyzed over a 90-day period. LAL-specific outcomes included the number of light treatments and uncorrected visual acuity stratified by ocular dominance.Results: The LAL group required significantly greater total clinic time (14:23 ± 4:36 vs 8:14 ± 2:12 hours; P < .0001), more visits (9 ± 1.37 vs 6 ± 0.48; P < .0001), and longer average visit duration (2:18 ± 0:55 vs 1:35 ± 0:54 minutes; P < .0001) compared with the monofocal group. Despite similar corrected distance visual acuity, the LAL group achieved high rates of spectacle independence through customized refractive targeting.Conclusions: Bilateral LAL implantation substantially increases postoperative visit burden and chair time relative to monofocal IOLs. These findings underscore the importance of preoperative counseling and scheduling considerations when offering customizable LAL technologies.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 6","pages":"e572-e577"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148205338","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}

Seven AI formulas were evaluated: Hill-RBF 3.0, Kane, PEARL-DGS, LSF Al, Hoffer QST, Karmona, and Nallasamy. Subgroup analysis was performed based on lens thickness (LT).Results: The Kane, PEARL-DGS, and Hoffer QST formulas exhibited no significant systematic bias (all P > .05) and demonstrated comparable refractive predictability in the overall cohort. In the thin lens subgroup (LT < 4 mm), the PEARL-DGS, LSF Al, and Hoffer QST yielded superior precision. In the intermediate subgroup (4 mm ⩽ LT < 5 mm), the Hill-RBF 3.0, Kane, and PEARL-DGS achieved higher accuracy. Notably, in eyes with pronounced lens-related crowding (LT ⩾ 5 mm), the Hill-RBF 3.0, Kane, and Hoffer QST remained the most reliable.Conclusions: Lens thickness is a critical determinant of refractive outcomes in eyes with extremely shallow ACD. Given that no individual AI-based formula maintains optimal predictive performance across the entire spectrum of lens morphology, a stratified formula selection strategy is recommended. Specifically, the PEARL-DGS is prioritized for thin lenses, Kane for intermediate profiles, and Hoffer QST for eyes with pronounced lens disproportion.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 6","pages":"e586-e593"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148205342","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}

All measurements used polychromatic light and a model cornea inducing +0.27 µm of spherical aberration. Modulation transfer function (MTF), through-focus MTF (TF-MTF), area under the MTF (MTFa), and simulated visual acuity (SimVA) were evaluated across pupil diameters of 2 to 4.5 mm. Photic phenomena susceptibility was also assessed via point spread function (PSF) imaging.Results: The Galaxy demonstrated robust optical quality and an extended functional vision for small pupils (2 to 3 mm). At these apertures, the SimVA remained ≤0.2 logarithm of the minimum angle of resolution (logMAR) across a wide defocus range (+1.00 to -3.00 D). The Galaxy showed a distinct higher plateau in the 0.00 to -2.00 D defocus range on the TF-MTF curve for small pupils. PSF analysis also demonstrated a compact central peak and minimal halo rings. However, a significant decline in objective metrics, including SimVA, was observed with increasing defocus for pupils >3.5 mm.Conclusions: The Galaxy demonstrated an extended range of vision with good optical quality and a low degree of positive dysphotopsia, particularly at small pupil sizes. Optical performance at intermediate and near distances tends to decline notably as pupil diameter increases.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 6","pages":"e514-e521"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148205298","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}

Three consecutive preoperative single-operator scans of patients with cataract were analyzed using the updated wavefront analysis software of a SSOCT biometer (ANTERION; Heidelberg Engineering). Corneal higher order aberrations (HOAs) were quantified as paired polar Zernike magnitudes, dioptric vector components, individual signed Zernike coefficients, and root mean square (RMS) values. For each metric, pooled within-subject standard deviation (Sw), coefficient of variation, and intraclass correlation coefficient (ICC) were calculated. Primary analysis was done at a 4-mm optical zone, with additional 3- and 5-mm assessments to evaluate zone-dependent consistency.Results: Fifty-six eyes of 56 patients with cataract were included. All anterior, posterior, and total HOAs revealed repeatability limits (R = 2.77 × Sw) below 0.10 µm with ICCs of 0.76 to 0.97 and coefficients of variation less than 25% at 4 mm. For the total cornea, RMS HOA and spherical aberration showed repeatability limits of 0.07 µm (ICC: 0.89) and 0.03 µm (ICC: 0.84), respectively. Test-retest variance scaled with zone size (photopic to scotopic) and interindividual variation.Conclusions: Corneal optical quality can be reliably characterized from a SS-OCT biometer at optical zones relevant to refractive cataract surgery. Because measurement uncertainty can impair clinical decision-making, repeatability limits should be considered if wavefront metrics are employed to inform intraocular lens design selection or outcome-based research.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 6","pages":"e601-e610"},"PeriodicalIF":3.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148205268","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 lens axis was marked preoperatively, and the insertion points of the sutures were marked 2 mm from the limbus and 2 mm on each side of the toric marks. Polypropylene 6-0 or 7-0 sutures were inserted through the sclera and threaded through the designated holes in the intraocular lens (IOL) haptics. Four-point fixation was achieved by creation of four external flanges.Results: Fifteen lenses were implanted in 15 eyes lacking capsular support.

Analysis of demographic and topographic features was performed.Results: The median age was 19 years (range: 17 to 23 years) and the male-to-female ratio was 5:2. The median mean keratometry (Km) was 57.70 diopters (D) (range: 51.80 to 60.70 D), maximum keratometry (Kmax) was 62.50 D (range: 55.10 to 68.10 D), and minimum pachymetry was 422 microns (range: 390 to 456 microns) before the CXL. The location of cone was central in all 7 eyes. At the visit preceding the occurrence of hydrops, the median Km was 54.50 D (range: 52.80 to 63.40 D), Kmax was 62.30 D (range: 57.40 to 79.00 D), and the minimum pachymetry was 375 microns (range: 313 to 404 microns). The median time from CXL to occurrence of hydrops was 39.3 months (range: 18.9 to 59.1 months). Although clinically there was flattening and reduction in pachymetry noted, there was no statistically significant difference in the keratometry and pachymetry values from baseline to after CXL. No significant antecedent history of coughing, sneezing, or eye rubbing could be elicited.Conclusions: The occurrence of hydrops after CXL is rare. Eye rubbing associated with allergic conditions is the specific predisposition. A clinically noteworthy feature was a reduction in pachymetry in eyes that developed hydrops. Due to the rarity of hydrops following prior CXL, reporting this event and reviewing the clinical and topographic features may enhance understanding in future studies.","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"42 6","pages":"e549-e556"},"PeriodicalIF":2.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148205317","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}
