VITREOUS LOSS IN CATARACT SURGERY: GENERAL ANESTHESIA VS LOCAL ANESTHESIA
Abstract
Introduction. Vitreous loss (VL) is one of the most serious ocular complications during cataract surgery without correct management may causes other serious complications and sometimes visual loss. By selecting the correct method of anesthesia (general or local anesthesia) it is possible to reduce the incidence of this complication and consequent events. The aim of this research is to determine the incidence of VL in cataract surgery with local and general anesthesia and comparing them with each other.
Methods. This survey was conducted in 210 patients over 40 years old who had been operated for cataract surgery. Subjects were randomized in two groups (general vs local anesthesia). There is no premeditations in anyone.
Findings. The incidence of VL in general and local anesthesia was 3.6 and 9.1 percent, respectively (P<0.05). The groups were similar with respect to demographic data and potential confounding variables.
Conclusion. The incidence of vitreous loss during cataract surgery under local anesthesia is more than general anesthesia. If general anesthesia is contraindicated, it is better to use sedative drugs during local anesthesia for cataract surgery to prevent vitreous loss.
