PURPOSE: To analyze early clinical outcomes of aspheric micro-monovision LASIK for correction of presbyopia and myopia with or without astigmatism.
METHODS: Prospective, non-comparative case series of 80 eyes of 40 patients with a mean age of 43.4 +/- 4.9 years (range: 38 to 63 years) treated bilaterally using an aspheric micro-monovision protocol. The target refraction was plano for the distance eye and between -0.75 and -2.25 diopters (D) for the near eye. Visual acuity, ocular aberrations, contrast sensitivity, corneal topography, amplitude of accommodation, binocular sensorial function, and satisfaction score questionnaires were evaluated at 3 months after surgery.
RESULTS: Three months after surgery, the mean spherical equivalent (SE) refraction in the distance eye was -0.08 +/- 0.27 D, whereas the attempted and achieved SE in the near eye were -1.41 +/- 0.28 and -1.32 +/- 0.35 D, respectively. Ninety-three percent of eyes were within +/- 0.50 D of target correction of SE. The uncorrected distance visual acuity (UDVA) after surgery was -0.10 +/- 0.06 logMAR (20/15.5), 0.22 +/- 0.12 logMAR (20/34), and -0.11 +/- 0.06 logMAR (20/15), for distance eyes, near eyes, and binocularly, respectively. Ninety-five percent of patients achieved simultaneously uncorrected distance visual acuity 0.0 logMAR (20/20) or better and uncorrected near visual acuity J2 (20/25) or better. Stability was achieved from 1 week of follow-up. The overall satisfaction score for surgery was 92 +/- 6.
CONCLUSIONS: The aspheric micro-monovision protocol provided a well-tolerated and effective means for treating myopic astigmatism and alleviating presbyopic symptoms simultaneously.
