PURPOSE To study the safety, effectiveness and predictability of phakic IOL (ICL Visian) to correct Chinese patients with high myopia.
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. |
