At 90 days, conventional SICS superior incisions gave 1.92 +/- 0.53 D against the rule and temporal incisions 1.57 +/- 0.24 D with the rule astigmatism. Phacoemulsification clear corneal incisions showed 1.08 +/- 0.36 D and scleral pocket 1.23 +/- 0.71 D astigmatism.

Strontium aluminate (SrAl2O4) exhibits a monoclinic structure at room temperature (RT) and transforms to a hexagonal structure at above 650 °C, reported previously in the literature. In this article, we have shown a stable, high temperature hexagonal phase of SrAl2O4 (SAO) at RT by synthesizing a SAO-ZnO composite through a combustion technique. While SAO crystallizes in the monoclinic phase by adding 2.5 wt% of ZnO, a stable hexagonal phase of SAO at RT has been obtained for 20 wt% of ZnO. Further, the hexagonal phase of SAO transforms to a monoclinic phase after increasing the calcination temperature from 700 to 1200 °C. The role of ZnO in determining the structure and photoluminescence properties of these composites are discussed.
