Popis: PURPOSETo compare the results of wavefront-guided custom LASIK and the Toric Implantable Collamer Lens (TICL) in the correction of myopic astigmatism. METHODSThis observational, non-randomized study compared clinical efficacy results 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 diopters (D) and –7.00 to –11.00 D. RESULTSThe 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 (PP CONCLUSIONSAlthough 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.
