Abstract

Objective To evaluate the use of Lenstar LS900 in the implantation of an intraocular contact lens （Visian Implantable Collamer Lens， ICL）. Methods The clinical data of patients with hypermyopia who underwent ICL implantation from January 2012 to June 2013 were retrospectively analyzed. Comparisons between preoperative and postoperative visual acuity （logMAR）， intraocular pressure， and corneal endothelial cell were measured. Postoperative ICL vault， angle-opening distance 500 μm from the scleral spur （AOD 500）， and the shape of the anterior surface of the iris were evaluated. The measurement data were analyzed with a paired t test， and the correlation between preoperative spherical equivalent and predicted error （PE） was done with Pearson correlation analysis. Results Twenty-seven patients （54 eyes） were included. Postoperative uncorrected visual acuity （UCVA）（0.06±0.05） improved significantly compared with preoperative UCVA （1.22±0.33）（t=25.306， P＜0.01）， and there was no statistically significant difference with preoperative best corrected visual acuity （BCVA）（0.06±0.05）（t=-0.640， P>0.05）. Postoperative spherical equivalent （SE） error （-0.21±0.1 D） decreased significantly compared with preoperative SE error （-9.34±1.97 D）（t=34.304， P<0.01）. There was no significant difference between preoperative and postoperative intraocular pressure （13.82±1.83 mmHg and 14.93±2.12 mmHg， respectively）（t=1.851， P>0.05）. The endothelial cell loss rate at 3 months postoperatively was 2.69%±2.16%. ICL vault for 72% of the eyes was in the ideal range at 3 months postoperatively. No cataracts formed in any of the patients during the follow-up period. Conclusion The use of Lenstar LS900 in ICL implantation is safe and effective. Postoperative refractive error is accurate， and the ICL vault is in an ideal range in most patients.
