Due to the demand for bugs fixing and feature enhancements, developers inevitably need to update in-use software systems. Instead of shutting down a running system before updating, it is often desirable and sometimes mandatory to patch the running software system on the fly, with a mechanism generally referred as dynamic software updating (DSU). Practical(More)
Dynamic software updating (DSU) is a technique that can update running software systems without stopping them. Most existing approaches require programmer participation to guarantee the correctness of dynamic updating. However, manually preparing dynamic updating is error-prone and time-consuming. Therefore, other approaches prefer to aggressively perform(More)
Dynamic software updating (DSU) aims to patch software for fixing bugs or adding functions while it is running. Before update, developers need to make a dynamic patch ready, which includes update points, state transformers and a corresponding code patch. Existing practice mostly assumes manual preparation of dynamic patches, but this process can be both(More)
PURPOSE To describe the surgical technique and outcomes of "wet-peeling" deep anterior lamellar keratoplasty (DALK) using sterile water and blunt dissection in cases with corneal scarring after healed corneal hydrops. METHODS Manual DALK using a "wet-peeling" technique was performed in 20 eyes of 20 consecutive patients with healed corneal hydrops between(More)
PURPOSE To evaluate the feasibility, safety and efficacy of deep anterior lamellar keratoplasty (DALK) using precut anterior lamellar cap (ALC) for patients with herpes simplex keratitis. METHODS In this single-centre retrospective study, 48 consecutive patients with herpes simplex keratitis and having undergone DALK using either big bubble technique or(More)
OBJECTIVES To report the outcomes of viscoelastic-aided non-Descemet stripping automated endothelial keratoplasty (nDSAEK) to treat bullous keratopathy in vitrectomized and iris-lens diaphragm injured eyes. METHODS A prospective consecutive case series of eyes with bullous keratopathy underwent nDSAEK. About 0.15 to 0.2 mL cohesive viscoelastic was(More)
