N2  - Local or regional block is the preferred anesthetic technique for day case cataract surgery. Local  anesthesia has been associated with ischemic complication such as central retinal vascular occlusion and optic atrophy. Many factors may account for the dramatic reduction of pulsatile ocular blood flow after  anesthesia which may be due to volume effect or local anesthetic drugs causing  vasoconstriction. In the present study the target is to find the safest technique for anesthesia of  patients undergoing cataract surgery. It is now common that day case cataract surgery is done under different local anesthetic techniques. However, evidence is increasing that some of these techniques render hazardous to the patients' ocular circulation and can compromise the retinal blood flow, and this maybe more hazardous to patients in whom circulation is already compromised
