Abstract:
Objective:To investigate the operative skill of phacoemulsification for cataract patients,to explore the best access at early learning stage and to study the related complications.Methods:Learning included attending lectures (theoretical study),animal experiments and case selections.97 consecutive cases(100 eyes) of early stage patients underwent phacoemulsification under peribulbar anaesthesia,continuous curvilinear capsulorhexis(CCC)or open capsulotomy,hydrodissection or hydrodelineation,one or two had nuclear phacoemulsification and IOL implantation.Results:During the first and second half of learning stage,CCC were performed successfully in 38%and 74% of the cases respectively;furthermore the incidences of posterior capsuletearing were 30% and 12% respectively.63 eyes (53%) with postoperative corrected visual acuities over 0.5 were observed. Conclusion:CCC method with maintenance of anterior chamber and emulsification within capsule must be adopted,furthermore posterior capsule tearing and corneal edema should be prevented.Phacoemulsification could be a safe procedure even during the learning curve by means of learning step by step,training followed an appropriate programme,selecting the suitable cases and managing complications correctly.The successful transition to phacoemulsification would be completed.
