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.
