To efficacy and safety of the implantation of phakic anterior chamber intraocular lens in high myopia

Objective To investigate the efficacy and safety of the implantation of phakic anterior chamber intraocular lens to correct high myopia.Methods Phakic anterior chamber intraocular lensimplantation(AC-IOL-PM)through scleral tunnel incision was performed on 92 eyes of 51 high myopic patients.The average age of patients was 28 14 years(18～45 years)old.The preoperative corrected visual acuity was 0 15～1 0.The mean preoperative spherical equivalent and astigmatism was (-14 90±1 1)D and (-1 38±0 3)D respectively.The mean diopter of IOL was (-14 82±1 33)D.Results The uncorrected visual acuity improved in all cases postoperatively,with 79 eyes (85 87%) achieving ≥0 5.After surgery,the uncorrected visual acuity improved in 63 eyes (68 48%) than the mean best corrected visual acuity(BCVA).The mean postoperative shpherical equivalent and astigmatism was (-0 54±0 37)D and (-0 67±0 14)D respectively.The average follow up was 18 months(12～30 months).No severe complications happened.Conclusions The implantation of phakic anterior chamber intraocular lens to correct high myopia is a safe,effective procedure serving as a refractive surgery.It is worth to spread due to good outcome of visual acuity,low incidence of complications,high predictability and stability.
