Visual Outcome after Cataract Surgery at the University College Hospital; Ibadan

Aim: The aim of this study was to determine the visual outcome of patients who had cataract surgery in the University College Hospital Ibadan. Methodology: This is an observational descriptive; longitudinal study of consecutive patients undergoing cataract surgery at the University College Hospital conducted between May and October 2007. A total of 184 patients who presented to the hospital and met the inclusion criteria were recruited into the study. Patients were examined preoperatively; 1st day postoperatively and 8th week postoperatively. Results: The mean age was 66.5 years; and the male to female ratio was 1.2:1. Preoperatively; 137 patients (74.5) were blind in the operated eye; while 39 patients (23.6) were blind in both eyes at presentation. At 1st day postoperatively; 87 patients (47.3) had pinhole visual acuity of 6/6-6/18. Best corrected vision after refraction eight weeks postoperatively showed that 127 patients out of 161 patients (78.8) had good vision while 28 patients (17.4) had borderline vision; and six patients (3.8) had severe visual impairment after refraction. The number of bilaterally blind patients also reduced from 39 (23.6) to one (0.6). Uncorrected refractive error was the commonest cause of poor vision prior to refraction. Glaucoma was the commonest ocular co-morbidity accounting for poor vision in 9.1of patients eight weeks after cataract surgery. Conclusion: This study demonstrates that good results can be obtained with cataract surgery and intraocular lens implantation in the developing world. More attention should be directed towards ensuring that successful outcomes are indeed being realized by continued monitoring of postoperative visual outcomes and prompt refraction for all patients

Clinical Evaluation of a Self-Etch Adhesive System in Non-Carious Cervical Lesions

Background: All-in one adhesive systems reduce the number of steps and thus possible soures of error that may occur in clinical wage of adhesives; it is hoped that they also have good clinical performance. Objective: To evaluate the clinical performance of a selfetch adhesive system - Adper's Prompt L-Pop in noncarious cervical lesions over a six months period. Method: One hundred and eighty-one (181) restorations were placed by one operator for 35 patients. The self-etch adhesive was applied to the cavity and composite was used to restore the teeth. The restorations were evaluated at baseline; 3 months and 6 months according to the modified Ryge's criteria. Restorations were monitored for postoperative sensitivity; retention rates and marginal adaptation. Results: At six months; 160 restorations were available for evaluation in 32 patients. The retention rate was 96.3; postoperative sensitivity was scored Alpha for all restorations (no sensitivity); and 3.7restorations had marginal adaptation failure at six months. Conclusion: The adhesive system tested exhibited very good clinical performance at the end of six months
