To evaluate the effect of toric intraocular lens implantation in cataract patient with corneal opacity and high astigmatism. Thirty-one eyes of 31 patients who underwent cataract surgery with toric intraocular lens implantation were included. All patients had corneal opacity with astigmatism. Preoperative total corneal astigmatism was determined considering posterior astigmatism using a rotating Scheimpflug camera (Pentacam®: Oculus, Wetzlar, Germany). At 2 months after toric intraocular lens implantation, we evaluated residual astigmatism, uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA). Postoperative UCVA and BCVA (0.30 ± 0.17, 0.22 ± 0.16LogMAR) were statistically improved compared to preoperative UCVA and BCVA (1.2 ± 0.34, 1.1 ± 0.30LogMAR, respectively) (P < 0.01). Postoperative residual refractive astigmatism (1.2 ± 0.35D) was statistically reduced compared to preoperative refractive astigmatism (2.4 ± 0.65D) (P < 0.05). Preoperative and postoperative total corneal astigmatism values were not statistically different. All eyes achieved postoperative visual acuity as good as or better than preoperative one. The size of corneal opacity covering pupil had significant negative correlation with postoperative UCVA and BCVA (logMAR) (R = 0.91 P < 0.05 and R = 0.92 P < 0.05, respectively). Toric intraocular lens implantation can improve UCVA, BCVA, and refractive astigmatism in cataract patient with corneal opacity. The size of corneal opacity covering pupil is the major prognostic factor for postoperative visual improvement. Therefore, toric intraocular lens implantation should be considered for cataract patients who have corneal opacity with high astigmatism.

白内障角膜混浊患者复曲面人工晶状体植入

要评估复曲面人工晶状体植入术对白内障角膜混浊和高散光患者的疗效。包括31例接受了复曲面人工晶状体植入术的白内障手术患者的31只眼睛。所有患者均患有角膜混浊并散光。考虑到后散光，使用旋转的Scheimpflug相机（Pentacam®：Oculus，Wetzlar，德国）确定术前总角膜散光。复曲面人工晶状体植入后2个月，我们评估了残留散光，未矫正视力（UCVA）和最佳矫正视力（BCVA）。与术前UCVA和BCVA（分别为1.2±0.34、1.1±0.30LogMAR）相比，术后UCVA和BCVA（0.30±0.17，0.22±0.16LogMAR）有统计学上的改善（P <0.01）。术后残余屈光散光（1。与术前屈光散光（2.4±0.65D）相比，统计学上降低了2±0.35D（P <0.05）。术前和术后角膜总散光值无统计学差异。所有眼睛的术后视力都达到或优于术前。角膜混浊覆盖瞳孔的大小与术后UCVA和BCVA（logMAR）呈显着负相关（分别为R = 0.91 P <0.05和R = 0.92 P <0.05）。复曲面人工晶状体植入可以改善患有角膜混浊的白内障患者的UCVA，BCVA和屈光散光。覆盖瞳孔的角膜混浊的大小是术后视力改善的主要预后因素。因此，
