Abstract
Objective To explore the surgical approach and effectiveness of the cataract extraction after manual fragmentation and emulsification of nucleus with 3.0 mm tunnel limbus incision through predicted bulbar conjunctiva after surface anesthesia,integrated with the implantation of preloaded foldable artificial intraocular lens.Methods Mter surface anesthesia,a 3.0 mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 50 eyes of 50 cases with Ⅰ ～ Ⅲ nuclear cataract.And after the fragmentation and emulsification of nucleus which consists of splitting,separating,smashing,and disturbing of the nucleus,the preloaded foldable intraocular lens was implanted.After the operation,without enswathement,the eye was monitored for postoperative complications and variation of eyesight.Results 6 hours after the operation,26 eyes had their eyesight ≥0.3,taking up 52％ of the whole; one day after operation,41 eyes had their eyesight ≥0.5,taking up 82％ of the whole ; one week after operation,46 eyes had their visual acuity ≥0.5,taking up 92％ of the whole; one month after operation,48 eyes had their visual acuity ≥0.5,taking up 96％ of the whole.There was no complication during-operation or postoperatively.Conclusion Manual fragmentation and emulsification of nucleus with foldable intraocular lens implantation is a fairly ideal and practical surgery.
