Visual outcomes and incidence of vitreous loss among third-year ophthalmology residents performing manual small incision cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM:To determine the visual outcome and the incidence of vitreous loss in patients undergoing manual small incision cataract surgery(MSICS)by third-year ophthalmology residents.METHODS:Hospital records of 799 consecutive patients undergoing MSICS at Department of Ophthalmology,Prapokklao Hospital by third-year ophthalmology residents between July 2005 and June 2007 were reviewed.Bestcorrected visual acuity(BCVA)were compared between the eyes operated by residents and those operated by the staffs.For the complication of vitreous loss,the study group(patients with vitreous loss)were compared with the control group(patients without vitreous loss)using analytic case-control study.RESULTS:One month postoperatively,91.0%of patients in resident group and 92.5%in the staff group had visual acuity of 6/18 or better.The difference in visual outcome between the two groups was not statistically significant(P =0.526).The incidence of vitreous loss among residents was 5.01%(20/399)and 1.00%(4/400)among the staff.The overall incidence of vitreous loss was 3.0%.The odds that the eyes in the resident group would have an intraoperative complication of vitreous loss were 5.22 times,the odds that the eyes in the staff group would have such a complication(P = 0.002,95%confidential interval(Cl)of relative risk =1.769-15.426).CONCLUSION:Good visual acuity can be achieved after resident perfoming MSICS.The vitreous loss rate in this study is high.
