Cost analysis of vitrectomy under local versus general anesthesia in a developing country.

PURPOSE: To report cost reductions of vitrectomy under local anesthesia. PATIENTS AND METHODS: This was a retrospective cohort study using medical records of consecutive patients undergoing vitrectomy surgery for retinal detachment under general or local anesthesia. Data of patient's fulfilling the inclusion criteria were included in the study. The patients were divided into two groups: Group 1 (local anesthesia) and Group 2 (general anesthesia). The preoperative data were checked and validated by a peer group consisting of two ophthalmologists, two internists, and two anesthesiologists independently in a blind manner. The calculation of the cost was done using the cost minimization analysis. The cost data were obtained from the finance division of the hospital for each individual treatment. The cost data included unit cost of laboratory tests, surgery, and medications. RESULT: There were 100 subjects (50 subjects in each group) assessed by peer groups and declared eligible to undergo surgery under either local or general anesthesia. Both groups were equal. The total average cost for vitreous surgery under general anesthesia for each patient was $322.17, whereas for local anesthesia it was $220.57. The mean difference was $101.60 (46.06%) saving on local anesthesia. CONCLUSION: Vitrectomy surgery under local anesthesia can reduce the cost by almost half that of general anesthesia. The present study showed that the type of anesthesia determined the ultimate cost for the surgery. Hence, surgery under local anesthesia appears affordable and cost-effective, especially in a developing country like Indonesia.

Learning curve of sutureless transconjunctival 20-gauge vitrectomy.

BACKGROUND: To report the learning curve of transition from 20-gauge (20 G) conventional vitrectomy to a 20 G sutureless vitrectomy technique. MATERIALS AND METHODS: This is a retrospective descriptive case study of 32 eyes from 32 consecutive patients who underwent sutureless 20 G pars plana vitrectomy. A 20 G microvitreoretinal blade was introduced, beveled transconjunctivally, slowly, parallel with the limbus, creating a conjunctivoscleral tunnel incision. Study participants were divided into three groups, and surgical time, induced astigmatism, and complications were compared. RESULTS: Of 32 consecutive patients, there was no significant difference in induced astigmatism or maneuvering between the early learning curve and other groups. The true learning curve was the first three patients. There were three cases where suturing the sclerotomy was necessary: one port in each case, three of 32 cases (9.3%), or three of 96 ports (2.9%). CONCLUSION: There were no significant difficulties in surgical maneuvers while performing 20 g sutureless vitrectomy.
