Clear lens phacoemulsification with foldable intraocular lens implantation in middle and old people for correction of high myopia

Objective To assess phacoemulsification with foldable intraocular lens implantation as an effecgtive,safe technique for the correction of high myopia in middle and old people.Methods A series of 55 eyes of 34 high myopia patients in middle and old people had clear lens extraction by phacoemulsification and foldable intraocular lens implantation through clear cornea incision.The average age of patients was 54.7 years(42～68 years).The preoperative corrected visual acuity was 0.1～0.6.The mean preoperative spherical equivalent was -14.31±4.73D.The mean postoperative follow-up was 28.5 months ±3.81(8～37 months).Results The uncorrected visual acuity and the corrected visual acuity was improved in all cases postoperatively.The best corrected visual acuity was from 0.2 to 1.0 3m postoperatively.49 eyes having achieved the best corrected visual acuity of 0.5 or better were accounted for 89.1%.The mean postoperative spherical equivalent was -1.82±0.52D.There were no significant difference between preoperative and 3m postoperative mean corneal astigmatism(t=1.813,P0.05).The 4 eyes of all case occurred posterior capsular opacification(7.3%).No other complications occurred.Conclusions phacoemulsification with foldable intraocular lens implantation for the correction of high myopia in middle and old people is a safe,effective procedure as a refractive surgery.It is necessary for careful examination of retinal periphery.The technique is associated with low incidence of intraoperative and postoperative complication and good outcome of visual acuity.
