RESUMO
The aim of this study was to assess the changes in visual function (VF) and quality of life (QOL) among patients following blindness prevention surgery in a rural area of Eastern China. The prospective study selected cataract patients via mobile eye screening camps. VF and QOL questionnaires originally developed by Fletcher et al were completed prior to and 6 months after surgery. Small-incision cataract surgery (SICS) with posterior chamber intraocular lens (IOL) implantation was performed on patients by a blindness prevention surgery group. The VF and QOL scores of 178 cataract patients preoperatively were 48.58±31.18 and 65.97±26.77, respectively. The scores decreased in proportion to decreasing vision status. The VF and QOL scale scores were significantly correlated with the vision grade of the patient (rVF=-17.2093, t=-10.87, P<0.001, rQOL=-13.1399, t=-8.87, P<0.001) and age (rVF=-0.6505, t=-3.87, P<0.001, rQOL=- 0.3309, t=-2.10, P=0.037). A total of 131 patients responded to the second survey, VF and QOL scores increased significantly over a six-month postoperative period (VF=83.21±16.40, P<0.001; QOL=86.53±16.33, P<0.001). The VF scale scores were correlated with the grade of vision and residence area, the QOL scale scores were correlated with the grade of vision and gender. The VF and QOL of patients were significantly improved by performing SICS with posterior chamber IOL implantation collectively in a short period in rural areas of Eastern China. It is important to follow-up cataract patients postoperatively as untreated complications of the surgery may affect the stability of VF and QOL postoperatively.
