| Abstract | ||
| Purpose: To assess the efficacy of the Toric Implantable Collamer Lens (ICL) to treat moderate to high myopic astigmatism. Design: Prospective nonrandomized clinical trial. Participants: Fifty eyes of 34 patients with between -2.5 and -19.0 diopters (D) of myopia and-1 to -6 D of astigmatism participated in this clinical trial of the Toric ICL. Intervention: Implantation of the Toric ICL. Main Outcome Measures: Uncorrected visual acuity (UCVA), refraction, best spectacle-corrected visual acuity (BSCVA), postoperative UCVA, BSCVA and refraction , adverse events, and postoperative complications. Results: At 12 months postoperatively, the proportion of eyes with 6/12 or better UCVA (50%) was identical to the proportion of eyes with preoperative 6/12 or better BSCVA (50%);82% percent of eyes achieved 6/18 or better 12-month UCVA, whereas 66% of eyes had 6/18 or better BSCVA preoperatively . The mean manifest refractive cylinder dropped from 3.38 DC at base line to 0.455 DC postoperatively. Furthermore, 84.0% had< or= 0.5 D and 80.0% had 0.25 D or less of refractive cylinder postoperatively. The mean MRSE improved from -12.26 D preoperatively to 0.05 D to 0.195 at 12 months postoperatively. Postoperatively 36% of eyes had a BSCVA of 6/9 or better, compared with a preoperative level of 24%.Best pectacle-corrected visual acuity improved more than 2 lines in 9 eyes at 12 months postoperatively; a 2-lines improvement was observed in 8 eyes. At the 12-month follow-up, 26 eyes had an increase in BSCVA, in contrast to only 3 eyes with a 1-line loss and 17 eyes with no change. The reported complications in this study were one eye with visually insignificant cataract, one eye with partial patency of peripheral iridoctomy which was treated with YAG laser and rotation of the toric ICL in 6 eyes. Despite visual compromise after rotation of ICL, nobody needed reoperation for replacement of lens. Conclusion: The results support the efficacy and predictability of Toric ICL implantation to treat moderate to high myopic astigmatism. | ||
