Methods: Seventy eyes from 38 patients who underwent surgery between 2002-2006 with V4 ICL implantation were analyzed. Pre-intervention data included corrected distance visual acuity (CDVA), refraction, and intraocular pressure (IOP). At the 19-year mark, CDVA, refraction, IOP, endothelial count, and vault were measured using Tomey Casia 2 anterior pole tomography, along with recording long-term events. Setting: Single-center. Design: Retrospective observational study Results: The operated patients had a spherical correction between -4 and -21D and a cylinder up to 7.5D. The mean CDVA (decimal) at the 17-year check-up was 0.89±0.18, with a spherical equivalent of -1.05±1.36D. Intraocular pressure has remained stable, as mean measurements prior to surgery and currently, was 15.16 ± 2.54mmHg and 16.19 ± 3.29 mmHg respectively. The endothelial cell count showed values of 2191 ± 386 cells/mm2, with a maximum of 2804 cells and a minimum of 1125 cells. Finally, the vault obtained was 348.53 ± 234.58mm. Over the years, 2 eyes developed angle closure glaucoma, and 9 eyes were operated on for the development of anterior subcapsular cataracts. Conclusions: Visian ICL implantation demonstrated long-term visual and refractive stability, indicating it as a low-risk procedure. The ICL V4 model yielded satisfactory results for myopia and astigmatism correction after 17 years.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"189 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140932710","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}

Setting: Rothschild Foundation, Paris, France. Design: Prospective interventional case series. Methods: Anterior corneal specular Placido topography using OPD-Scan® II (NIDEK, Gammagori, Japan) was performed in 97 eyes of 67 patients undergoing PRK for myopia, before and after epithelium removal. The differences in axial keratometry, asphericity and astigmatism were computed. Results: After epithelial peeling, some Placido-normal classified corneas became KCS. Therefore, we have subdivided this group into two groups: one of normal classified corneas which stayed normal after epithelium removal (Group NN), and one of corneas that became KCS classified (Group NK).The mean difference in axial mean keratometry in the third central millimeter rings was +0.50 ± 0.24 D, 0.69 ± 0.31 D and 0.49 ± 0.35 D and the mean difference in the magnitude of epithelial induced astigmatism in the first central millimetre ring was 0.37 D x 89° (positive cylinder), 0.54 D 86° and 0.52 D 86° respectively in Group NN, NK and KK (KCS corneas that stayed KCS). These differences were significant (p< 0.0001). Preoperative keratometry was the only predictive factor differentiating Group NN from NK (p<0.001). Conclusions: The epithelial layer tended to reduce the magnitude of the Bowman layer’s astigmatism, prolateness and keratometry, more importantly in Group NK. In KK group we found a similar trend as in normal eyes (Group NN). The epithelium would be able to mask Bowman layer’s irregularities until a certain degree of severity.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"191 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140840634","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}

Setting: Chukyo Eye Clinic, Nagoya, Japan. Design: Retrospective observational study. Methods: This study included patients undergoing preoperative examination for cataract surgery with the new Barrett True AL (BTAL) and Emmetropia Verifying Optical (EVO) formulas using segmental refractive index, and conventional Barrett Universal II (BU II) formula using equivalent refractive index. The predicted refractive error of each formula was compared with the postoperative subjective spherical equivalent. Results: The mean prediction error (MPE) in the short AL group (≤ 22 mm; 44 eyes) was 0.32 ± 0.40 D for BU II, 0.22 ± 0.37 D for BTAL, and 0.10 ± 0.37 D for EVO (P < 0.0001). MPE in the long AL group (≥ 26 mm; 92 eyes) was 0.01 ± 0.32 D for BU II, 0.04 ± 0.32 D for BTAL, and 0.09 ± 0.32 D for EVO (P < 0.0001). In patients with an AL ≥ 28 mm, BU II showed a myopic trend in 57.1% of cases, while BTAL and EVO showed a hyperopic trend in 71.4%. The MPE for patients with an AL ≥ 28 mm was -0.16 ± 0.34 D for BU II, 0.18 ± 0.33 D for BTAL, and 0.16 ± 0.32 D for EVO (P < 0.0001).

Setting: Instituto de Oftalmología Santa Fe, Santa Fe, Argentina. Design: Prospective, randomized, single-surgeon, observational study. Methods: Eyes with aphakia and no capsular support were included. They were divided into 2 groups: one was programmed for a double-needle flanged intrascleral IOL fixation as originally described by Shin Yamane with NSP and the second group had a modified SP technique. Flange depth was measured with anterior-segment optical coherence tomography (AS-OCT) at 1 month, 3 months, 6 months, and 12 months postoperatively, and the results were compared. Results: Each group comprised 18 eyes of 18 patients, giving a total of 36 flanges per group. The groups were comparable preoperatively. At 12 months, uncorrected distance visual acuity and corrected distance visual acuity (CDVA) were not statistically different for both groups (P = .333; P = .448). Spherical equivalent (SEQ) was not significantly different between groups at 12 months postoperatively (P = .078). AS-OCT revealed a significantly deeper flange position for the SP group at 1 month, 3 months, 6 months, and 12 months postoperatively (P < .05). Conclusions: When performing a double-needle intrascleral IOL fixation in aphakic eyes with no capsular support, a modified scleral pocket technique provides a significantly deeper flange position with no difference in CDVA or SEQ 12 months postoperatively.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"96 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140802376","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}

Setting: Private clinic, Zlin, Czech Republic. Design: Prospective, consecutive case series. Methods: 180 eyes undergoing cataract surgery had anterior capsule staining with microfiltered 0.4% trypan blue solution before selective laser capsulotomy. The first 60 eyes (Group 1) had mydriatic dilated pupil centered capsulotomies. The next 60 eyes (Group 2) were centered on the trypan blue central landmark (TCL). The final 60 capsulotomies (Group 3) were centered on the patient fixated coaxial Purkinje reflex (CPR). Measurements between key anatomical landmarks and the TCL, CPR capsulotomies, and implanted intraocular lens (IOL) center were made. Results: The TCL, observed in >94% of eyes in the study, coincided with the CPR with a displacement of <0.1 ± 0.1 mm. Group 1 capsulotomies were noticeably decentered on the IOLs by 0.3 ± 0.2 mm. The Group 2 symmetrical IOL relationship was maintained with a decentration of 0.15 ± 0.1 mm. Group 3 had a similar decentration with the IOLs with 0.15 ± 0.1 mm. Verification with IOLMaster 700 data and CALLISTO Eye System showed that the CPR and the TCL were coincident with the measured visual axis. Conclusions: The clearly visible TCL served as an alternate landmark to the patient fixated CPR, and being on the anterior capsule was not sensitive to tilt. Further patient compliance was not required. Both were superior to dilated pupil centration, to achieve symmetric IOL coverage. This has application for both capsulotomies and capsulorhexes.","PeriodicalId":15233,"journal":{"name":"Journal of Cataract & Refractive Surgery","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140802550","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}
