Analyze The Cost-effectiveness Of Phacoemulsification Underwater And With Ophthalmic Viscoelastic Agent

Objective: To evaluate the clinical effects and cost-effectiveness of of two different surgical methods of phacoemulsification underwater and viscoelastic cataract.To evaluate the application of anterior chamber maintenance in cataract phacoemulsification Intraoperative potency analysis.Method: 74 cases age-related cataract patients were randomly divided into 34 patients in group A(ACM group)which was performed by phacoemulsification with continuous anterior chamber infusion,and 40 patients in group B(Viscoelastic group)by phacoemulsification with an ophthalmic viscoelastic agent.Uncorrected visual acuity(UCVA)、Best corrected visual acuity(BCVA)、Corneal endothelial cell density were measured preoperatively and on postoperative days 7 and 30 before and postoperative.And the intraocular pressure were measured preoperatively and on postoperative days 1 and 7.Intraoperative and postoperative complications were recorded in both groups.The cost of surgery was recorded.This study evaluated the clinical effect of phacoemulsification with continuous underwater cataract;the difference between the uncorrected visual acuity of the two groups of cataract patients before surgery and one month after surgery was taken as the improvementamount to compare the surgical effect of phacoemulsification.The ratio of the average cost of surgery to the average improvement in visual acuity in the two groups of cataract patients was used to extrapolate the cost-effectiveness of phacoemulsification under ACM and viscoelastic cataract surgery.Result: There was no significant difference in the uncorrected visual acuity(UCVA),corrected visual acuity(BCVA),corneal endothelial cell density,corneal endothelial cell loss at days 7 and 30,and intraocular pressure at days 1and 7 after operation between group A and group B.The cost-effectiveness ratios for the first month after surgery in the two groups were 11,205.30 yuan for the ACM group and 12,127.32 yuan for the viscoelastic group.The cost-effectiveness of the viscoelastic group was 922.02 yuan higher than that of the ACM group,which has clinical significance.Conclusion: The phacoemulsification and drainage of phacoemulsification can achieve the same clinical effect of viscoelastic,and reduce the cost of surgery.It has a higher cost-effectiveness ratio and is worthy of promotion in developing countries and primary hospitals.
