Parajumpers Kodiak Down Parka,Parajumpers Gobi CanadaPURPOSE: To compare the results of wavefront-guided custom LASIK and the Toric Implantable Collamer Lens (TICL) in the correction of myopic astigmatism.METHODS: This observational, non-randomized study compared clinical efficacy results Parajumpers Gobi Canada from the TICL's US Food and Drug Administration Clinical Trial and published Summaries of Safety and Effectiveness of two wavefront-guided lasers: STAR S4 CustomVue excimer laser system (VISX Inc) and LADARVision4000 CustomCornea excimer laser system (Alcon Laboratories Inc). Preoperative myopic refractive error was divided into two groups: -3.00 to -7.00 Parajumpers Kodiak Down Parka diopters (D) and -7.00 to -11.00 D.RESULTS: The percentage of eyes with uncorrected visual acuity (UCVA) of 20/20 and 20/40 and predictability of manifest refraction spherical equivalent within +/- 0.50 and +/- 1.00 D in the three groups was similar with only one statistically significant difference (TICL versus Alcon within +/- 1.00 D: 97% versus 82%; P = .008). The TICL had significantly better postoperative best spectacle-corrected visual acuity (BSCVA) compared to preoperative BSCVA than both the VISX CustomVue and Alcon CustomCornea (P < .001). The TICL postoperative UCVA outcomes compared to preoperative BSCVA were significantly better than Alcon CustomCornea outcomes (P < .001). Additionally, almost half (48%) of the TICL cases had improvement in postoperative UCVA compared to preoperative BSCVA, whereas only 23% of the Alcon CustomCornea eyes showed improvement.CONCLUSIONS: Although comparable in clinical efficacy outcomes, the TICL had a significantly better postoperative improvement in BSCVA and significantly better postoperative UCVA than preoperative BSCVA. The TICL can be considered as an alternative to LASIK through the full range of use.
