Objective To evaluate the clinical efficacy of surgical correction for high myopia using phakic intraocular lens.Methods Clinical data about 80 eyes of 41 patients who had implantation of implantable contact lenses (ICL) for the correction of high myopia in Chinese PLA General Hospital from September 2011 to march2012 were retrospectively analyzed. There were 15 males and 26 females with the average age of (27.0±6.2) years old (range: 19-41 years old). The uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction spherical equivalent (MRSE), intraocular pressure (IOP), endothelial cell density (ECD), anterior chamber depth (ACD), space between crystalline lens and intraocular lens (vault) were tested and recorded preoperatively and followed at different time points postoperatively.Results The mean follow-up time was 12.3±3.1 months. Postoperative UCVA were improved in all eyes by 9 lines in snellen chart, with 91.3%≥0.5 and 71.25%≥1.0. BCVA were maintained or improved in all eyes, with 56.3% (45/80) improved by 1 line, 22.5% (18/80) by 2 lines, 3.7% (3/80) by 3 lines. The surgery efficacy index and safety index were 1.13±0.33 and 1.25±0.35, respectively. The mean MRSE was -11.62±3.37 D preoperatively and -0.15±0.96 D postoperatively, 68 eyes (87.5%) were within 1D of emmetropia, 51 eyes (63.8%) were within 0.5 D of emmetropia. Transient IOP elevation occurred in 7 eyes (8.75%) within 1 week postoperatively and stabilized after proper management. ECD was 2 861±413 /mm2 preoperatively and 2 682±498 /mm2 postoperatively, which showed no statistically significant difference (P>0.05). ACD was 3.21±0.25 mm preoperatively and 2.91±0.30 mm postoperatively, which showed statistically significant difference (P<0.01). The mean vault 1 month postoperatively was 711 +/- 354 μm with 8 eyes (10%)≥1 000 μm and 3 eyes (3.75%)≤200 μm. One eye (1.25%) reported glare and halo postoperatively.ConclusionICL implantation for the correction of high myopia is effective, safe and predictable.
