visual outcomes of toric implantable collamer lens for correction of compound myopic astigmatism

purpose : to assess the visual and refractive outcomes after implantation of toric implantable collamer lens (t-icl) in compound myopic astigmatism methods : in this prospective study, 28 eyes with manifest refraction spherical equivalent (mrse) errors of -10.94±4.09 diopter (d) and mean cylindrical errors of -3.47±1.39 d underwent t-icl implantation. six months after surgery, best corrected and uncorrected visual acuity (bcva, ucva), manifest refraction and surgical complications were assessed. results : the mean postoperative mrse was -0.35±0.34 d (range, -1.25 to 0.37), and the mean postoperative refractive cylinder was -0.78±0.45 d (range, -1.50 to 0.00). postoperatively, manifest spherical equivalent (se) was within ±1.00 d in 96% of eyes, and refractive cylinder was equal or less than 1.00 d in 79% of eyes. fourteen eyes (50%) had uncorrected distance visual acuity (udva) of 20/20 or better, and 27 eyes (96%) had udva of 20/40 or better. all changes in visual and refractive data were statistically significant (p<0.05). conclusion : t-icl is safe and effective for correction of compound myopic astigmatism in patients who are not good candidate for corneal refractive surgery.    iranian journal of ophthalmology 201325(2):155-162 © 2013 by the iranian society of ophthalmology
