Quantitative Study Of Anterior Chamber Angle With Ultrasound Biomicroscopy After High Myopia Cataract Surgery

Objective: With the development of small-incision phacoemulsification and foldable intraocular lenses implantation , more and more cataract patients have received such operation, including high myopia. Because of vitreous chamber elongation high myopia have some other complications such as: scleral staphyloma, vitreous degeneration, zonular weakness. Therefore, cataract surgery of high myopia was considered to have more risks of retinal detachment, glaucoma postoperatively. Now small-incision cataract surgery have made it safer for high myopia. In this study, Ultrasound biomicroscopy is used to quantitatively measure ACD,AOD₅₀₀, AA, TCPD, ICPD before and after surgery. By comparing the changes, this study tries to explore the advantages of small-incision phacoemulsification and foldable IOL implantation for high myopia.Methods: Small-incision phacoemulsification and foldable IOL implantation were performed in 60 eyes of 60 patients, which was divided into two groups. Group 1 included 30 eyes of 30 senile cataract patients without other eye diseases. Group 2 included 30 eyes of 30 senile high myopic cataract patients whose axial length were between 26mm³0mm. The changes of anterior chamber angle , anterior chamber distance were determined quantitatively by using UBM before and post-operation 1month,...
