Clinical observation of phacoemulsification through 1.8 mm coaxial microincision for treatment of complicated cataract after silicone oil infusion

Abstract

Objective To observe the clinical effect and safety of the coaxial 1.8mm micro incision cataract operation in treatment of complicated cataract after silicone oil infusion.Methods Thirty-six cases (36 eyes) of complicated cataract after silicone oil infusion in our hospital were randomly divided into two groups.Micro incision group:18 cases (18 eyes) received coaxial 1.8mm micro incisions for phacoemulsification combined with intraocular lens implantation operation; small incision group:18 cases (18 eyes) received traditional coaxial 3.0mm small incision phacoemulsification combined with intraocular lens implantation operation.Postoperative 1D,1 week,1 month,3 months follow-up,visual acuity,corneal topography,corneal endothelial cell count and complication was recorded.Results Postoperative visual acuity of the two groups was improved significantly.One week after operation,the best corrected visual acuity of micro incision group was increased than that of the small incision group,and there was significant difference between the two groups,(P ＜0.05); postoperative corneal topographic astigmatism in micro incision group less than in the small incision group,there was significant difference between the two groups (P ＜0.05); postoperative 1 D,corneal endothelial cell average density in micro incision group was higher than in the small incisiongroup and there was significant difference between the two groups (P ＜0.05).The two groups were successfully implanted intraocular lens without posterior capsular rupture of the membranes.After a follow-up of 3 months,2 cases with recurrent retinal detachment in the small incision group,and micro incision group did not occur.Conclusions The coaxial 1.8mm micro incision cataract operation in treatment of complicated cataract after silicone oil infusion is more safe and effective.It is worthy of clinical application.
