| PURPOSE To observe the changes of refraction,visual quality,the morphology of anterior capsule and intraocular lens(IOL)position in cataract patients with high myopia after phacoemulsification.METHODS A total of 9 cataract patients(15 eyes)with high myopia were enrolled as high myopia group(an axial length of ≥26mm),and 9 age-related cataract patients(15 eyes)with normal axial length(an axial length of ≥22mm and ≤24mm)were enrolled as control group.The phacoemulsification combined with IOL implantation was performed by the same experienced cataract surgeon.At 1 day,1 week,1 month,3months and 6 months follow-up after operation,data of two groups was collected,including modulation transfer function cutoff(MTFcutoff)by the optical quality analysis system(OQAS II),the area of the anterior capsular opening with dilated pupil by the slit-lamp photography,and tilt and decentration of IOL and anterior chamber depth(ACD)by Pentacam,which is compared between two groups.RESULTS In the high myopia group,best corrected visual acuity(BCVA)decreased at 3 and 6 months after operation,diopter decreased at 1week after surgery and increased followed,MTFcutoff decreased at 1 week to 6 months after surgery.The area of the anterior capsular opening decreased at at 1 month to 6 months after operation significantly,and the reduction range and duration were greater than the control group.The tilt and decentration of IOL in the high myopia group increased continuously after operation.CONCLUSIONS Cataract patients with high myopia were more prone to have anterior capsular contraction,which may lead to increased tilt and decentration of IOL after operation.At the postoperative follow-up of cataract patients with high myopia,the morphology of anterior capsule and IOL position should earn significantly respect. |
