To investigate the efficacy and safety of the implantation of phakic anterior chamber intraocular lens (IOL) for high myopia.

A consecutive group of 73 eyes in 41 patients with -7.00 to -30.00 diopters (D) of myopia were implanted.

All of 73 eyes were implanted successfully and have been followed-up for 3 m (months). The uncorrected visual acuity was from FC/33 cm to 0.2 pre-operatively and 0.1 to 1.03 m post-operatively. The best corrected visual acuity (BCVA) was from 0.05 to 1.0 pre-operatively and 0.1 to 1.03 m post-operatively. The post-operative BCVA of every eye was not worse than the pre-operative one. The refractive diopters were from -7.00 to -30.00 D pre-operatively and -6.00 to +2.50 D 3 m post-operatively. There were no significant differences between pre- and 3 m post-operative mean corneal astigmatism (t=1.751, P=0.082) and mean intraocular pressure (IOP) (t=1.181, P=0.240), respectively. The mean counts of endothelial cells was (2680±538)/mm² pre-operatively and (2514±420)/mm² 3 m post-operatively. There was no significant difference (t=1.182, P=0.242) though it decreased 6.19%. No severe complications occurred.

The implantation of phakic anterior chamber IOL for high myopia is predictable, reversible and controllable with simple manipulation. No severe complication occurred in 3 m post-operatively, and long-time follow-up is still required.
