Following MSICS there was a 12.12% (p=0.001) endothelial cell loss. It was 10.81% in viscoexpression group, 11.3% in irrigating vectis group and 14.28% in phacosandwich group.

Main outcome measures were indications for surgery, IOL implantation technique, and the necessity of anterior vitrectomy. MEDLINE database and Google scholar were used to identify relevant past publications.Results: We included 37 eyes of 30 patients with a mean age of 62.1 ± 10.2 years, with 16 eyes (43.2%) with OPC undergoing IOL exchange. Mean interval between IOL implantation and IOL exchange was 61.50 ± 62.00 months in the OPC group and 15.81 ± 15.03 months in the CPC group. The most common indication was optical phenomena in 18 cases (48%). In the OPC group, intraoperative anterior vitrectomy was necessary twice as often (OPC nine cases (56%) vs. CPC five cases (24%)). Bag-to-bag IOL exchange was performed in all eyes with CPC, and in 10/16 (62%) with OPC (p=0.009). Postoperative complications were seen in a total of 7/16 eyes (43.7%) with OPC and 3/21 (14.3%) with CPC (p=0.012).Conclusion: The success rate of repositioning an IOL within a bag with OPC is less than that achieved with CPC. A vitrectomy is typically required when attempting a bag-to-bag IOL exchange with an OPC.

Cochrane Armitage trend test was used to assess patient and surgeon characteristics over time. Multivariable logistic regression was used to evaluate surgeon characteristics associated with performing ISBCS.Results: Among 1,190,169 BPCS, 3,954 (0.33%) were ISBCS.

Corneas remained either uninfected, or were infected with S. aureus, and P. aeruginosa, respectively, and were either left untreated, or were instilled with 0.1% riboflavin or 0.1% rose bengal. Corneal buttons were prepared, and corneal LT was measured at 365 nm and 522 nm using a spectrophotometer. LTs were calculated and compared. Transmission electron microscopy (TEM) was used to visualize structural damage and bacteria within infected corneas.Results: Riboflavin-saturated corneas infected by S. aureus or P. aeruginosa (LT = 0.77% [0.41-1.87] and 0.81% [0.23, 1.46]) exhibited 3.18-fold and 3.02-fold lower LTs than uninfected corneas (LT = 2.45% [2.15, 5.89]) (both p-values < 0.001).

The primary aim was to assess the axial length (AL) acquisition success rates, and secondary aims included comparing parameters obtained from the three devices and evaluating postoperative refractive prediction errors.Setting: Chukyo Eye Clinic, Nagoya, Japan.Design: Retrospective observational study.Methods: The study included patients undergoing preoperative assessments for cataract surgery using the three biometers. The AL acquisition success rates and parameters obtained from the three devices were compared and the postoperative refractive prediction errors (defined as the difference between subjective refractive error and predicted refractive error) were assessed at one month after surgery.Results: The study included 361 eyes from 361 patients. The AL acquisition success rates for all patients were 100.0% (n=361) (OCTB1), 98.6% (n=356) (OCTB2), and 96.7% (AS-OCTB) (P < .0001), and those for nuclear sclerosis of grade 4 or higher were 100.0%, 87.8%, and 87.8%, respectively (P = .007). The AL of mature cataract was measurable only with OCTB1 using the enhanced retina visualization mode. Although there were significant differences in parameters obtained on the three devices, there were no significant differences in postoperative refractive prediction errors.Conclusions: OCTB1 demonstrated the highest AL acquisition success rate and was able to measure AL even in eyes with dense or mature cataract. AS-OCTB using a wavelength of 1300 nm showed lower AL acquisition success rates compared to the other two devices probably due to reduced light transmission through the vitreous body.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877269","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}

Data on the type and number of prior refractive surgeries were collected, in addition to the timing and number of postoperative adjustments. The primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and the percentage (%) of eyes within ±1.00 diopter (D), ±0.50 D, and ±0.25 D and of their refractive target.Results: 94 eyes from 77 patients were included. 28% (n = 26) were a history of 4-cut RK, 12% (n = 11) were 6-cut RK, 55% (n = 52) were 8-cut RK, and 5% (n = 5) were 16-cut RK. Overall, 82% (n = 77) of all eyes achieved 20/25 UDVA or better, 74% (n = 70) of all eyes achieved UDVA of 20/20 or better, and 94% (n = 88) were correctable to 20/20 or better postoperatively. For refractive outcomes, 98% (n = 92) of eyes were within ±1.00 D of target, 88% (n = 83) were within ±0.50 D, and 69% (n = 65) were within ±0.25 D of preoperative refractive target.Conclusions: Patients with a history of RK achieved favorable visual and refractive outcomes with the LAL. Postoperative light adjustments should be delayed to allow for refractive stabilization. The LAL is a promising option for post-RK patients who are motivated to obtain favorable uncorrected acuity after cataract surgery.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142836562","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}
