Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced? tip(n=207) or the IPS using the 30-degree Kelman? tip(n=205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis(NS) grade, cumulated dissipated energy(CDE), preoperative corrected distance visual acuity(CDVA), and CDVA at one month were recorded. RESULTS: CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS(n=70) compared with IPS(n=44)(P=0.010). Surgical complications were not statistically different between the two subcohorts(P=0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs(VOs) at one month for NS grade III and above cataracts were-0.17 log MAR(6/4.5) in the CPS and-0.15 log MAR(6/4.5) in the IPS subcohort respectively(P=0.033).CONCLUSION: CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei.展开更多

The deceased was both in military service as a centurion and in civil service as a decurion of the mentioned town. That it was a person of importance is indicated not only by the gravestone inscription but also by the relief depiction of the deceased, shown to be holding a volumen in his hand. Since the monument is chipped and damaged in the upper part, it can only be determined that it was a stela type funerary monument. The main goal of this work is to underline the importance of this monument as a great archaeological treaser, since it is the first written source from Roman period for the town with the three initial letters--Bal, as well as the source for further excavation and the researching of military units of the first word Nova. Two questions will stay open: when the settlement becomes municipium, and the full name of the town.展开更多
