LASIK for Myopia with Presbyopia Using the Aspheric Micro-Monovision Technique

Purpose: To evaluate the efficacy, safety, and satisfaction of patients who underwent the aspheric micro-monovision protocol for the correction of myopia with presbyopia. Methods: A retrospective, noncomparative study included 40 eyes of 20 consecutive patients with myopia and presbyopia who were treated with LASIK-induced micro-monovision. Monocular and binocular visual outcomes of uncorrected and best-corrected distance, intermediate, and near visual acuity were measured. Depth of focus, spherical aberration, stereopsis and satisfaction were evaluated before surgery and 3 months after surgery. Results: Mean patient age was 48.7 years. Monocular uncorrected distance visual acuity was 0.8 in 94% of dominant eyes, and monocular uncorrected near visual acuity was J3 in 94% in non-dominant eyes. Binocular uncorrected near visual acuity was J2 in 94% and J5 in 100% of dominant and non-dominant patient eyes, respectively. Binocular uncorrected distance visual acuity was 1.0 in 100% of patients, and binocular uncorrected near visual acuity was J2 in 94% of patients. Our results showed a significant improvement in depth of focus and a positive shift in spherical aberration in dominant eyes; however, there were no significant changes in the non-dominant eyes. There was no change in stereopsis or contrast sensitivity at any of the tested spatial frequencies. Satisfactory scores were achieved in all eyes. Conclusions: The aspheric myopic micro-monovision protocol was well-tolerated, stable, and effective for treating patients with presbyopia in myopic astigmatism.
