Abstract:
Objective To evaluate efficacy ,stability and safety after implantation of toric implantable collamer lens (TICL) to correct moderate to high myopic astigmatism .Methods This study evaluated 125 eyes of 71 patients with moderate to high myopic astigmatism who accepted TICL implantation .LogMAR uncorrected(UCVA) and best corrected(BCVA) visual acuity ,intraocular pressure ,cycloplegic refraction and manifest refraction examination were assessed preoperatively on 3 ,6 ,12 months postoperatively . The rotation of TICL axis were measured on 3 ,6 ,12 months postoperatively .Results 12 months postoperatively ,the logarithm of the minimum angle of resolution(LogMAR) UCVA were 0 .064 ± 0 .157 which were remarkably better than preoperative BCVA (P<0 .01) .119 eyes(95 .2% ) had postoperative UCVA better than or equal to preoperative BCVA .The manifest spherical refrac‐tion(absolute value) was (0 .36 ± 0 .41)D .105 (84 .0% ) eyes were within ± 0 .5 D .The mean manifest refractive cylinder was (-0 .63 ± 0 .61)D .109(87 .2% ) eyes had ≤ -1 .00 D .The mean rotation on 12 months postoperatively was (4 .76 ± 6 .14)° .The rotation of 101(80 .8% ) eyes were within 5 degrees .No vision threatening complications occurred during the observation period . Conclusion Implantation of TICL is safe and stable in the treatment of moderate to high myopic astigmatism .TICL is an ideal sur‐gical option to treat moderate to high myopic astigmatism .
