Patients' Preoperative Expectation and Outcome of Cataract Surgery at Jimma University Specialized Hospital -Department of Ophthalmology

BACKGROUND Patient's satisfaction for a given treatment is an important clinical outcome because a satisfied patient is more likely to comply with treatments, attend follow-ups and advocate the service to others. Therefore, knowing patients' expectations before a planned procedure or treatment and the actual level of satisfaction and fulfillment of their initial expectations thereafter is much helpful. As far as the knowledge and experience of the researchers is concerned, there has not been any study conducted in Ethiopia to find out about patients' preoperative expectations and postoperative level of satisfaction for actual outcomes. This study was therefore, conducted to describe and find out the relationship between preoperative expectations of cataract patients and the actual postoperative experience and their satisfaction level following the surgery at ophthalmology department in Jimma University Specialized Hospital. METHODS A prospective cohort study of patients undergoing first eye cataract surgery was conducted from July 10 to Oct., 10, 2007 in the Ophthalmology department of Jimma University Specialized Hospital. Detailed interviews that included general and vision specific health status measures and patients' preoperative expectations for cataract surgery outcomes were performed followed by visual acuity testing. Postoperatively, visual acuity testing was taken again and patients' level of satisfaction with attained postoperative vision was assessed. Data were collected and filled in a separate questionnaire form for each patient, and entered into a computer and analyzed using SPSS for Windows version 12.0. RESULTS Of the 200 patients operated for cataract, 179 (89.5%) were followed for the whole five weeks. The average expected preoperative Visual Function-15 score was 96.3, compared to an achieved (postoperative) Visual Function-15 score of just 96.2. However, the most unrealistic expectations observed were reading small prints and doing fine handiwork. The final pinhole visual acuity postoperatively was ≤ 6/18 in 126 (70.4%) patients. Of the 78 (39%) patients who were bilaterally blind preoperatively, 5 (2.5%) patients remained blind postoperatively. CONCLUSIONS Significant improvements were obtained in clinical, functional, and perceived vision by cataract surgery involving extracapsular cataract extraction with posterior chamber intraocular lens implantations. Expectations regarding visual functioning after cataract surgery were very high, and in most cases and in most cases they were fulfilled.
