Abstract
This retrospective review examined the results of laser in situ keratomileusis (LASIK) performed to correct hyperopia, and hyperopic and mixed astigmatism using wider ablation diameters (optical zone diameter and overall ablation diameter) than those commonly used with the same and other lasers. The results in 53 eyes of 33 consecutive patients who underwent LASIK (Alcon LADARVision 4000) using a 7-mm optical zone diameter and a 3-mm transition zone for an overall 10-0 mm total ablation diameter were included in the analysis. The mean spheroequivalent attempted correction was +2.34 ± 2.09D. Six months after surgery, the mean spherical equivalent refractive error was − 0.22D ± 0.41D. Forty-two (79.2%) eyes were within ± 0.50D and 52 (98.1%) were within ± 1.0D of intended correction. Uncorrected visual acuity of 20/40 or better was achieved in 50 (94.3%) eyes, including 28(53%) eyes with 20/20 or better. No significant subjective nighttime symptoms, such as haloes or glare, were reported. The conclusion is that large ablation zones for hyperopia and hyperopic and mixed astigmatism are associated good visual outcomes and refractive predictability.—Michael D. Wagoner
