PURPOSE: To report the pre- and postoperative visual and topographical short-term results in hyperopic presbyopes, following asymmetrical Supracor LASIK.
SETTING: Clinical study at an ophthalmology clinic.
METHODS: A prospective, longitudinal, comparative case series of hyperopic patients with presbyopia treated using the Supracor technique. Preoperative data included dominant (DE) and non-dominant eye (NDE) mono- and binocular distance/near uncorrected and best corrected visual acuities (UCVA, BCVA), addition (Add), spherical equivalent (SE), pupillometry, mean topographic K (Km) and topographic astigmatism. Supracor (LASIK technique) was performed with the DE targeted to emmetropia and the NDE to –0.50 D. Postoperative results: mono- and binocular distance/near UCVA, BCVA, Add, accommodation range, SE, Km, topographic astigmatism and 3.0 mm / 5.0 mm area power. Statistical analysis of pre- and postoperative data included: mean, standard deviation, range, correlation coefficient and Student’s t-test (paired samples) (p ≤ 0.05 for statistical significance).
RESULTS: Twelve patients underwent uneventful Supracor LASIK. We enrolled 5 women and 7 men, mean age 52.2 years. Preoperative monocular distance UCVA was 0.51 ± 0.21, monocular near UCVA 0.40 ± 0.31, binocular distance UCVA 0.51 ± 21, binocular near UCVA 0.40 ± 0.25, pupil 5.6 ± 0.7, SE 1.2 ± 0.74, Add 2.0 ± 0.42, Km 43.1 ±1.2 and topographic astigmatism 0.7±0.4. Postoperative results: monocular distance UCVA 0.91 ± 0.15 (p < 0.001), monocular near UCVA 0.9 ± 0.2, binocular distance UCVA 1.0, binocular near UCVA 0.95 ± 0.13 (p < 0.001), SE –0.26 ± 0.35 (p < 0.001), Add 0.92 ± 0.5 (p < 0.001), Km 44.1 ± 0.9 (p < 0.001) and topographic astigmatism –0.83 ± 0.34 (p > 0.05).
CONCLUSIONS: Asymmetrical Supracor LASIK for hyperopic presbyopes significantly improved distance and near UCVA, both monocular and binocular, while eliminating or reducing spectacle dependence for near vision.
