Kết quả thị lực và khúc xạ sau phẫu thuật phaco với công suất thể thủy tinh nhân tạo tính bằng các công thức thế hệ mới

Abstract

Objective: To evaluate the visual acuity and refractive result after phacoemulsification surgery with the intraocular lens (IOL) power calculated by using the modern formula. Subject and method: Descriptive study performed on cataract patients who would be passed a phacoemulsification at Glaucoma Department, Vietnam National Institute of Ophthalmology from November 2015 to June 2016. Using the 3^rd and 4^th generation formulas to calculated the power of IOL. Result: 140 eyes were enrolled, 35% male, 65% female, and 67.82 ± 17.72 years old. After 3 months AV uncorrected were 55.7% above 20/30; 32.9% from 20/70 - 20/30 and 11.4% below 20/70; corrected AV were 63.3% above 20/30; 30.7% from 20/70 - 20/30 and 5.7% below 20/70. Residual refraction was low and fast on stability. After 3 months average spherical refraction was 0.29 ± 0.06, average equivalent sperical refraction was 0.39 ± 0.09. Good refractive results after 1 week of in 116 eyes (82.9%) after 1 month in 127 eyes (90.7%). Rose to 93.6% after 3 months. Conclusion: The phacoemulsification treatment with IOL power calculated by modern formulas has good visual acuity and residual refration after surgery.
