The long-term clinical performance of silicone hydrogels worn for 6- or 30-nights continuously was similar. Clinical markers of hypoxia were low in both groups, and the 6-night wear schedule was not superior to the 30-night wear schedule with regard to preventing lens spoilage, improving corneal physiology, or subjective symptoms of comfort and vision.

The ability of SRH to predict functional decline and mortality persists for the acutely unwell elderly presenting to the ED. SRH is a simple and valuable tool to assess the elderly in the ED and to identify high-risk patients who would benefit from comprehensive geriatric assessment aimed at delaying such outcomes.

Aim To investigate factors affecting refractive outcome following LASIK for myopia. Method Six hundred and seventy-four consecutive uncomplicated myopic LASIK surgeries, performed by a single surgeon, either using the Technolas 217 planoscan (n ¼ 372) or the NIDEK EC 5000 (n ¼ 302), were evaluated. Stratified random sampling was used to match the groups for refractive error, patient age, and gender. The final analysis included 302 patients from each treatment group. Conditions were identical for both surgeries, and pre-operative refractive errors were between À1.00 and À14.00 DS and oÀ1.50 DC. Refractive success was defined as À0.50 to þ 0.50 DS of the targeted refraction measured 3 months after surgery. A stepwise logistical regression analysis was used to determine variables associated with refractive failure. Results A successful refractive outcome was achieved in 78% (235/302) of surgeries using the Technolas laser and in 88% (266/302) using the NIDEK laser. Predictor variables for not achieving refractive success were pre-operative refractive error of above À5.00 DS, age more than 40 years, and surgery performed with the Technolas laser. Conclusion Both the Technolas 217 and the NIDEK EC-5000 excimer lasers achieve a successful refractive outcome in the majority of cases. However, patient and surgical factors can influence refractive outcome.
