Background:To evaluate the efficacy of manual mid-stromal dissection in stabilizing progressive ***:Surgeries were performed in 16 eyes of 14 patients with progressive *** eyes were examined before and at 1 day,1 week,1,3,6 and 12 months after surgery,and every 6 months ***(simK,Kmax and pachymetry),best corrected visual acuity(BCVA)and subjective refraction were recorded up to the latest follow-up visit(mean follow-up time 6.6±2.4 years).Results:All surgeries were uneventful,and no postoperative complications *** values(n=15)stabilized in 6/11 eyes(55%)with a preoperative Kmax60 D showed continued *** 11/15 eyes(73%)pachymetry was *** with spectacles remained stable in 7/12 eyes(58%)and improved≥2 Snellen lines in 5/12 eyes(42%).BCVA with a contact lens remained stable in 4/9 eyes(44%),improved≥2 Snellen lines in 3/9 eyes(33%)and deteriorated in 2/9 eyes(22%).Conclusions:Manual mid-stromal dissection was effective in 50%of keratoconic corneas with Kmax values<60 D and may be considered in cases ineligible for other interventions such as UV-crosslinking,stromal ring implantation or Bowman layer *** advantage of the procedure may be that the tissue is unaltered and that no synthetic or biological implant is required.

Despite many attempts to evaluate the effectiveness of case management for frail older people, systematic reviews including experimental designs show inconsistent results. Starting from the view that case management is a complex intervention occurring in multilayered realities, we conducted a realist evaluation of case management in Belgium, where this type of intervention is new. Realist approaches are particularly well suited to evaluate complex interventions as they seek to investigate iteratively the literature and empirical data to uncover mid-range theories underpinning the intervention under study. As such, realist evaluations are works in progress which provide tools to describe how, why and for whom an intervention is supposed to work. In this paper, we describe two mid-range theories that can explain why case management can help frail older people to remain at home, through the lens of capacity and social support.
