Global multi-site, prospective analysis of cataract surgery outcomes following ICHOM standards: the European CAT-Community

Abstract

Purpose To evaluate in a large sample of patients from 10 different European centers the results of cataract surgery, characterizing the relationship between patient-reported outcomes (PROMs) and clinician-reported outcome measures (CROMs). Methods Prospective non-interventional multicenter observational descriptive study analyzing the clinical outcomes of a total of 3799 cases undergoing cataract surgery (mean age: 72.7 years). In all cases, the cataract surgery standard developed by the International Consortium for Health Outcomes Measurements (ICHOM) was used to register the clinical data. Threemonth postoperative visual acuity and refraction data were considered CROMs, whereas Rasch-calibrated item 2 (RCCQ2) and total Catquest-9SF score (CQ) were considered PROMs. Results Postoperative corrected distance visual acuity (CDVA) was 0.3 logMAR or better in 88.7% (2505/2823) of eyes. Mean differences between preoperative and postoperative RCCQ2 and CQ scores were −3.09 and −2.39, respectively. Visual function improvement with surgery was reported by 91.5% (2163/2364) of patients. Statistically significant, although weak,

Systematic review for the development of a core outcome set for monofocal intraocular lenses for cataract surgery

“…The use of COS has been developed to define the most relevant outcomes for all stakeholders. Although many institutions and organizations are supporting the development of relevant metrics, comprehensive and standardized identification of outcome sets has been lacking ( 26 , 27 ). The COMET (Core Outcome Measures in Effectiveness Trials) initiative has started exploring the setting of clinical trials to guide the development, implementation, evaluation and updating of core outcome sets ( 4 , 17 , 18 , 28 ).…”

If you like it, should you really put a ring in it?

“…Indeed, the referenced International Consortium for Health Outcomes Measurement (ICHOM) standards has been rarely sighted (and cited) in literature since. [7][8][9] Posterior capsular opacification (PCO) following cataract surgery is a case in point. The reported prevalence of PCO varies and its strategies for prevention are not absolute.…”

“…It is disappointing that such a consensus statement for a minimum standard data set of outcome measures for cataract surgery developed as early as 2015, has not become uniform. Indeed, the referenced International Consortium for Health Outcomes Measurement (ICHOM) standards has been rarely sighted (and cited) in literature since 7–9 …”

Keeping patient outcome surveys in pace with presbyopia correction technology

“…11 Consortium for Health Outcomes Measurements, both clinician-reported outcomes and patient-reported outcomes should be considered when evaluating cataract surgery outcomes. 15 In addition, I believe it is time to seriously start moving toward universal and standardized clinician and patient questionnaires that incorporate visual acuity and patient expectations and patient personality type. Properly worded questionnaires taken preoperatively and postoperatively would flush out and confirm expectations for the surgeon and the patient.…”
