Purpose: To determine the effect of femtosecond laser cutting parameters on small-incision lenticule extraction (SMILE) results by evaluating cap thickness, interface light scattering, and visual and refractive outcomes. Setting: SynsLaser Clinic, Oslo, Norway. Design: Retrospective. Methods: 58 right eyes treated with SMILE using a programmed cap thickness of 130 μm were divided into 2 groups according to laser settings: Group 1: 165 nJ pulse energy and 4.5 μm spot separation (n = 36); Group 2: 125 nJ pulse energy and 4.2 μm spot separation (n = 22). The cap thickness was measured within the central 5 mm of the horizontal meridian using spectral-domain optical coherence tomography. Postoperative interface light scattering was graded based on the percentage area showing light scattering: 0: no scattering; 1: ≤25%; 2: 26% to 50%; 3: 51% to 75%; and 4: >75%. Results: At 3 months postoperatively, cap thickness was 138.9 ± 6.2 μm in Group 1 and 149.4 ± 3.5 μm in Group 2 (P < .001). Interface scattering was 0.9 ± 1.0 in Group 1 and 0.3 ± 0.9 in Group 2 (P < .05), with no scattering in 33.3% and 86.4% of the eyes, respectively. The postoperative spherical equivalent refraction was −0.03 ± 0.44 diopters (D) in Group 1 and −0.04 ± 0.31 D in Group 2. In Group 1, 83.3% of the eyes were within ± 0.5 D of the desired outcome, and 69.4% achieved an uncorrected distance visual acuity of 20/20 or better. In Group 2, these values were 95.5% and 86.4%, respectively. Conclusions: Lower pulse energy with tighter spots seems to reduce interface light scattering and improve refractive outcomes while also significantly increasing cap thickness.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"78 1","pages":"1253 - 1259"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76037336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: To report the initial safety and effectiveness profile for an anterior shape-changing, modular IOL, Juvene IOL (JIOL), for the treatment of aphakia and presbyopia after removal of the natural crystalline lens due to cataract. Setting: 2 private practices in Monterrey and Tijuana, Mexico. Design: Exploratory prospective multicenter open-label noncomparative clinical trial. Methods: A convenience sample of patients aged 50 to 80 years with planned cataract surgery was recruited to undergo unilateral or bilateral implantation with the JIOL. Patients were required to complete an informed consent and be able to dilate to at least 6.0 mm pharmacologically, be in good overall health, and have no significant eye health history to qualify. Visual acuities, defocus curves, and contrast sensitivity were measured for all patients 12 months postoperatively. Results: 51 of 58 eyes completed the 12-month visit. Intraoperative complication rates were extremely low (n = 1; missed base lens tab). The most frequent adverse events (AEs) were prolonged inflammation (N = 6) and cystoid macular edema (N = 4); all AEs were resolved without sequelae by the 12-month visit. The mean monocular logMAR corrected distance visual acuity, distance-corrected intermediate visual acuity, and distance-corrected near visual acuity were 0.01, 0.08, and 0.24, respectively. Defocus testing showed visual acuity > 20/40 from approximately +1.00 through −2.00 diopters. Binocular implantation (n = 16) provided superior performance over monocular implantation. Conclusions: The JIOL offers a new solution to treat presbyopia, providing clear functional vision performance across a range of distances with an acceptable initial safety profile.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"1 1","pages":"1134 - 1140"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90847566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Between limited and full-blown expulsive choroidal hemorrhage, the former was having better prognosis. Purpose: To study the risk factors, clinical features, management, and outcomes of intraoperative expulsive choroidal hemorrhage (ECH) during cataract surgery. Setting: Aravind Eye Hospital, Madurai, Tamil Nadu, India. Design: Retrospective hospital-based study. Methods: Of the 1 167 250 patients who underwent cataract surgery between 2008 and 2020, patients diagnosed with intraoperative ECH were included. Demography, ocular and systemic risk factors, visual acuity, type of ocular anesthesia, intraoperative and postoperative records, management, and surgical outcomes were analyzed. Results: 52 eyes (0.004%) of 1 167 250 patients had ECH. Of the 52 cases, 43 cases (incidence rate 0.006%) were reported in the years 2008 to 2015 and 9 cases (incidence rate 0.002%) in the years 2016 to 2020. The change in the ocular anesthesia from peribulbar and retrobulbar anesthesia (2008 to 2015) to sub-Tenon anesthesia (2016 to 2020) was associated with a reduced rate of ECH (P = .002). 28 eyes (53.8%) experienced limited ECH and 24 eyes (46.2%) full-blown ECH. The visual outcome was better in eyes with limited ECH compared with full-blown suprachoroidal hemorrhage in all follow-up visits. The median vision (interquartile range) before the cataract surgery and at postoperative day 1 were 1.30 (0.78 to 2.60) and 2.45 (1 to 2.75), respectively. The median final vision (interquartile range) after the secondary surgical intervention was 2.2 (0.60 to 2.60). Conclusions: This series included 52 eyes with ECH, recognized associations of ECH with different types of anesthesia and with different cataract surgical procedures, and described management of ECH. Postoperative visual outcome was poor.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"31 1","pages":"1037 - 1043"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80360080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: To evaluate the indications for pIOL explantation, pIOL survival time, and visual outcomes and access endothelial cell loss (ECL) after explantation. Setting: Ophthalmology Department, Centro Hospitalar Universitário do Porto, Portugal. Design: Retrospective longitudinal study. Methods: A chart review was performed for all consecutive patients who underwent pIOL explantation from January 2010 to December 2019 in a single center. Results: This study included 175 eyes of 112 patients (77% women). The mean pIOL survival was 12.9 ± 4.8 (3.7 to 28.6) years, and the mean follow-up period after explantation was 4.1 ± 3.0 (0.3 to 9.9) years. The most frequent causes for explantation were cataract formation (44.0%, n = 77) and ECL (50.3%, n = 88). During the follow-up period after explantation, the mean ECL rate was 2.27 ± 9.32%/year in the cataract group and −2.14 ± 10.24%/year in the ECL group, reflecting a positive change in cell density in the latter. 8 eyes (4.6%) required a corneal transplant during the follow-up. The mean corrected distance visual acuity was 0.17 ± 0.24 logMAR at the last visit. Conclusions: This study demonstrated that pIOL explantation, after a mean survival time of 13 years, was a safe procedure. The main causes for explantation were cataract formation and ECL. Most patients showed a sustained improvement in visual acuity and endothelial cell density after pIOL explantation, and yet its timing should be ideal to avoid irreversible complications.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"80 1","pages":"1004 - 1009"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88384551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
