Abstract:AIM: To assess the clinical outcome of the implantation of phakic posterior chamber Toric intraocular lens(TICL)for high myopia with astigmatism.
METHODS: Totally 50 eyes of 30 patients with high myopia and astigmatism were treated with TICL implantation from October 2009 to November 2011. The preoperative mean spherical equivalent was -10.75±2.65D, the mean cylindrical equivalent was -2.85±0.75D. All of the patients were followed up for 3 months to 2 years. Uncorrected and best-corrected visual acuity, refraction, intraocular pressure and endothelial cell morphometry, as well as the complications were observed.
RESULTS: The range of uncorrected visual acuity after operation was 0.5-1.2, mean 0.75±0.34. The range of preoperative best-corrected visual acuity was 0.3-1.0, mean 0.58±0.35. The mean best-corrected visual acuity after operation was 0.78±0.35. The uncorrected visual acuity after operation of 20 eyes was same and of 30 eyes was better than the preoperative best-corrected visual acuity. The mean spherical equivalent after operation was -0.52±0.35D, the mean cylindrical equivalent was 0.52±0.25D. Corneal endothelium counting before and after the operation had no significant difference. No serious complication was detected during the follow-up.
CONCLUSION: The implantation of phakic posterior chamber TICL for high myopia with astigmatism is safe and effective. It is a suitable treatment method for high myopia.
