Objective: To evaluate the effects of customized corneal collagen cross-linking (CXL) on higher-order aberrations (HOAs) in keratoconus (KC): vertical coma (VC), horizontal coma (HC), spherical aberration (SA), trefoil (TF) and astigmatism, compared with the same effects in healthy eyes undergoing CXL for low-grade myopia.
Methods: This mixed-designed study included 38 eyes of 38 patients with KC, treated and followed prospectively, who received customized epi-on CXL in high oxygen, and a retrospective control group of 23 eyes from 23 patients who underwent central 4-mm CXL treatment for low-grade myopia. VC, HC, SA, TF and keratometry values were obtained from Pentacam HR® measurements at baseline and at 1, 6, 12 and 24 months post-treatment.
Purpose: To analyse clinical characteristics and risk factors for post-operative endophthalmitis (POE) in a Swedish patient insurance database and compare prevalence of POE with two national quality registers.
Methods: We analysed 218 medical records of patients who claimed compensation for POE following ocular surgery from 2010 to 2020. The data were cross-referenced with national quality registers.
Purpose: To study the trend of delayed sequential bilateral cataract surgery (DSBCS) in Sweden in the past decade.
Methods: This register-based cohort study utilized data from the Swedish National Cataract Register (NCR) from 2010 through 2019. Register files from patients who underwent cataract surgery in both eyes during the study period were linked using their social security numbers.
Purpose: This cross-sectional survey study aimed to explore the phacoemulsification techniques among Swedish cataract surgeons, and investigate the association between technique preferences and surgical outcomes, particularly posterior capsular rupture (PCR).
Methods: A survey questionnaire was responded by 170 cataract surgeons and data from 192 494 cases, linked to the surgeons, were analysed from the Swedish National Cataract Registry (SNCR) for 2021-2022. Surgeons' demographic characteristics, surgical techniques and complications were assessed.
Purpose: To study the prioritization effects of the of COVID-19 pandemic on Swedish cataract surgery using a national healthcare registry with high coverage.
Setting: A study from the Swedish National Cataract Register (NCR), involving all patients undergoing cataract surgery in Sweden during 2019-2022 - before, during and after the COVID-19 pandemic.
Results: With the pandemic outbreak, the number of cataract surgeries fell by 22% in 2020 (15 369 procedures), albeit with large regional differences (-43% to +58%).
