Abstract
Objective To investigate the clinical effect of posterior chamber phakic intraocular lens implantation combined with astigmatic keratotomy for the correction of extreme myopia with astigmatism.Methods Thirteen patients ( n =18 eyes) with extreme myopia and astigmatism ( astigmatism≥1.5 D) were treated with posterior chamber phakic in-traocular lens implantation combined with astigmatic keratotomy.Observations of clinical effects included uncorrected visual acuity, best corrected visual acuity, refractive state, intraocular pressure and surgery related complications.Results Post-operative uncorrected visual acuity significantly improved and were better than preoperative best corrected visual acuity in all patients at 6 months after treatment.Average pre-and postoperative best corrected visual acuity at 1d, 1mo, 3mo, and 6mo were 0.62 ±0.21,0.74 ±0.20, 0.81 ±0.18, 0.85 ±0.18, 0.86 ±0.19, respectively.Average astigmatism were -1.88 ±0.35, -1.72 +0.60, -1.09 ±0.74, -0.83 ±0.52, 0.72 ±0.47 D, respectively.The difference is statisti-cally significant ( P <0.01) .No related complications, such as secondary glaucoma, cataract or others, were found in 6 months after operation.Conclusion Posterior chamber phakic intraocular lens implantation combined with astigmatic kera-totomy is a safe, effective and reliable way to correct high myopia with astigmatism.关键词
