[Implantation of phakic anterior chamber intraocular lens for high myopia]

OBJECTIVE: To investigate the efficacy and safety of the implantation of phakic anterior chamber intraocular lens for high myopia. METHODS: A consecutive group of 29 eyes in 16 patients with (-7.00 to -30.00) D of myopia were implanted. RESULTS: All of the 29 eyes were implanted successfully and followed-up 3 approximate, equals 6 months. The mean best corrected visual acuity was 0.50+/-0.26 pre-operatively and 0.73+/-0.263 months post-operatively, there was no significant difference t=2.043, P=0.051 . The mean refractive diopter was -18.03+/-5.54 D pre-operatively and -0.82+/-1.54 D post-operatively t=30.899 P=0.000 ; The mean intraocular pressure was 2.091+/-0.380 kPa pre-operatively and (1.734+/-0.572)kPa post-operatively t=1.98 P=0.07 ; The mean counts of endothelial cells was (2704+/-390 /mm2 pre-operatively and (2 519+/-278)/mm2 post-operatively (t=1.16 P=0.26). CONCLUSION: The implantation of phakic anterior chamber intraocular lens for high myopia is predictable, reversible and controllable with simple manipulation. Long- time following-up is still required.
