METHODS  The study involved 59 patients (104 eyes) with high myopia (spherical equivalent between -8.0 and -26.0 diopters). The mean patient age was 29.0 years. All the eyes received implantation of phakic IOL (ICL Visian), 28 eyes of which receiving Toric ICL. Followed-up examinations were scheduled for 1 day, 1 week, 1 and 3 months postoperatively.  

RESULTS  The preoperative BSCVA ranged from 1/20 to 20/20. At 3 months, 7 eyes (67%) which were under-corrected attained postoperative UCVA 1 line lower than preoperative BSCVA. 97 eyes (93.3%) achieved postoperative UCVA better than or equal to preoperative BSCVA. The  improvement in BSCVA ranged between 0 and 7 lines. The mean residual spheroequivalent was -0.73 ± 1.22D. The corneal endothelial cell showed no statistically significant difference to the preoperative level, with a loss of 4.0% (P > 0.05). The mean postoperative intraocular pressure (IOP, 14.7mmHg) was higher than the preoperative IOP (12.9mmHg, P <0.01).  6 eyes (5.8%) of 3 patients showed an increase in IOP from baseline of 10 mmHg and all were controlled to nomal range with topical medication. 5 patients (9 eyes) complained glare and night vision problems. Anterior Subcapsular Opacities were noticed in 1 eyes of a 46-aged female patient.

CONCLUSIONS  Phakic IOL (ICL Visian) implantation showed good safety, efficacy and predictability for correction of Chinese patients of high myopia with or without astigmatism.
