Purpose: To evaluate dissatisfied patients and those with subjectively worse visual ability after cataract surgery and to analyze how these factors relate to poor visual acuity results (worse than 20/40). Setting: Department of Ophthalmology, Norrlands University Hospital, Umea Sweden. Methods: A prospective, population-based study of cataract surgery outcome was conducted. All patients (459 surgeries) who had cataract surgery during a 1 year period were studied using seif-administered questionnaires and data from patient records. Outcome measures were (1) patient degree of satisfaction with the result, (2) subjective visual ability after surgery of visually demanding tasks such as reading, television viewing, orientation in unfamiliar surroundings, and distance estimation far and near, and (3) visual acuity results, Results: After surgery, 37 of the 459 cases (8%) were dissatisfied. These patients had a significantly lower age-corrected visual acuity in the operated eye than the satisfied patients (P < .0001). Ten percent said 1 or more visual ability was worse after their cataract surgery, logistic regression analysis revealed that the visual acuity in the better eye before surgery and age-related maculopathy were the most significant risk factors. Poor visual acuity after surgery in the operated eye was found in 22%, mostly as a result of concurrent age-related maculopathy, diabetes, or glaucoma. Four percent had no improvement in visual acuity in the operated eye. Conclusions: Dissatisfaction seemed to rely mostly on visual acuity in the operated eye. Low visual acuity in the better eye before surgery and age-related maculopathy were the most significant risk factors for subjectively worse visual ability after surgery. The degree of satisfaction after cataract surgery and changes in visual ability differed in important ways from visual acuity as a measure of visual function. (C) 1999 ASCRS and ESCRS.

Objective: To improve current clinical practices and ways of thinking about the problem of curable Third-World blindness resulting from cataract. Design: A two-site prospective, nonrandomized, comparative clinical trial. Participants: Patients from 2 distinct surgical venues underwent cataract surgery following the same carefully outlined protocol: 62 consecutive cases from the Tilganga Eye Centre in Katmandu, Nepal, and 207 cases from a remote eye camp in rural Chaughada, Nepal. Intervention: Extracapsular cataract extraction with posterior chamber intraocular lens (IOL) implantation surgery using a technique developed by Dr. Sanduk Ruit of the Tilganga Eye Centre in conjunction with the Medical Directorate of the Fred Hollows Foundation of Australia. Also presented is the teaching method used to help make local doctors proficient in this technique. Main Outcome Measures: Visual acuity recorded at 2 months after surgery as well as surgical complications. Results: Preoperative visual acuities for the 62 patients from the Tilganga Eye Centre ranged from 20/60 to light perception only (4 patients were untested), At 2 months after surgery, 87.1% had a best-corrected visual acuity of 20/60 or better. There were zero major surgical complications reported from the Tilganga group. Of the 207 patients at the Chaughada eye camp, preoperative visual acuities (recorded for 177 [85.5%]) ranged from 20/200 or greater to light perception only. One hundred eighty-nine (91.3%) of the patients returned for an examination at 2 months after surgery, at which time 54.5% had an uncorrected visual acuity of 20/60 or greater, improving to 74.1% with correction. There were six (2.9%) surgical complications documented at Chaughada. Conclusions: Because the average operative time using the technique presented here is less than 10 minutes per case and the cost per surgery is less than $20, the surgical results are significant in addressing the massive problem of cataract blindness in the Thir
