Clinical research of implantation of phakic anterior chamber intraocular lens for high myopia

[Objective] To evaluate the effect of anterior chamber intraocular lens implantation for high myopia.[Methods] One hundred ten eyes in 57 patients with 8.00 to 23.00 diopters of myopia were implanted with the intraocular lenses.These eyes then were checked with uncorrected visual acuity,corrected visual acuity,intraocular pressure(IOP) and corneal endothelial cells for 12 months post surgery.[Results] All surgeries of the 110 eyes were successful.The uncorrected visual acuity was 0.01 to 0.1 pre-operatively.The corrected visual acuity was improved to 0.3 in 82.3%,and 0.6 in 33.64% of those patients post-operatively.Pre-and post-operative IOP were (13.54±0.64) mmHg and(14.23±0.79) mmHg respectively.Endothelial cells were(3108±197)/mm2 and(2877±201)/mm2,with no significant difference.[Conclusions] The implantation of phakic anterior chamber IOL for high myopia is effective,safe and predictable.
