Special Issue Information

Dear Colleagues,

Randomized controlled trials (RCTs) are widely acknowledged for providing exceptionally strong evidence. Although RCTs are considered the gold standard in comparing the safety and efficacy of interventions, e.g., new drugs or treatment modalities, these studies are often limited by a short duration, small sample size, selective patient enrollment criteria, and very controlled settings. Moreover, according to the Declaration of Helsinki, any patient should receive the best proven intervention; therefore, it might be difficult to implement randomization in ocular surgery procedures.

To estimate the effectiveness of care practices in the real-world, alternative approaches are needed. Data on everyday practices need to be measured and evaluated routinely and non-selectively. Studies in the clinical practice setting are often termed as “real-world evidence” or “real-world data” studies. Real-world evidence (RWE) studies are feasible in providing estimates in large cohorts and expanded time frame among patients with variable comorbidities and care provision. Electronic databases allow information to assess long-term outcomes and endpoints and rare adverse events to provide robust evidence-based data on clinical practices. RWE data are increasingly exploited to support regulatory and administrative decision making and to guide best clinical practices to deal with the challenges in everyday care, but often the data remain scarce.

In this Special Issue of Life, titled "Real-World Evidence Studies on Cataract Surgery and Corneal Diseases", we aim to provide high-quality RWE data on general populations supported by diverse clinical situations. This Special Issue concentrates on the natural history of disease, prevalence, incidence, unmet medical needs, current treatment patterns and standard of care, patient outcomes and health economics, studies on rare adverse events and high-risk groups, and secondary end-point studies with a longer duration on cataract surgery and corneal diseases.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Purpose: To assess clinical outcomes of corneal cross-linking (CXL) intervention in a population diagnosed with progressive keratoconus. Methods: This single-center retrospective cohort study included consecutive patients who underwent standard CXL or accelerated CXL for progressive keratoconus at a major teaching hospital in southern Israel between January 2015 and December 2019. Patients’ medical files were reviewed, and pre-operative and post-operative data regarding demographics and clinical and tomographic characteristics were extracted and analyzed. Results: This study included 166 patients (representing 198 eyes), out of which 98 patients (123 eyes) were ethnically Bedouin, and 68 patients (75 eyes) were ethnically Jewish. Overall, 126 patients (144 eyes) had a follow-up of at least 12 months (16.84 ± 5.76). The mean patient age was 20.62 ± 7.1 years old. There were significant baseline differences between the two ethnic groups in best-corrected visual acuity (BCVA; p < 0.001), uncorrected visual acuity (UCVA; p < 0.001), mean keratometry (p = 0.028), and corneal thickness (p < 0.001). Significant changes in BCVA, UCVA, and pachymetry parameters within each group were found after 12 months. Negative binomial regression analysis showed a maximal keratometry below 55D (RR = 1.247, p < 0.001), and a standard CXL procedure (RR = 1.147, p = 0.041) are significantly related to the stability of KC after 12 months. However, the effect size of the origin of patients is negligible (RR = 1.047, p = 0.47). Conclusions: In this study, the Bedouin population suffered from more progressive keratoconus when compared to the Jewish population. CXL was significantly effective in improving BCVA and UCVA in both groups after 12 months of follow-up. The effect size of the origin of patients on the stability of KC was found to be negligible.
