Purpose:
To analyze the 6-month outcomes of the treatment combination of the monocular bi-aspheric ablation profile (PresbyMAX) and contralateral aspheric monofocal laser in situ keratomileusis (LASIK) ablation profile for correction of myopia and presbyopia.
Setting:
Yonsei University College of Medicine and Eyereum Eye Clinic, Seoul, South Korea.
Design:
Retrospective case series.
Methods:
This was a retrospective case review of 92 patients (184 eyes) diagnosed with myopia who underwent uneventful simultaneous bi-aspheric ablation in the nondominant eye and aspheric monofocal regular LASIK in the dominant eye to correct myopia and presbyopia between January 2017 and August 2020. Monocular and binocular uncorrected distance visual acuity (UDVA) and near visual acuity (UNVA), and corrected distance visual acuity and near visual acuity were analyzed postoperatively.
Results:
At 6 months postoperatively, the mean UDVAs (logMAR) in the dominant and nondominant eyes were 0.01 ± 0.02 and 0.26 ± 0.15, respectively. Furthermore, all treated dominant eyes achieved 20/20 or better monocular UDVA, and 84% achieved 20/16 or better monocular UDVA. In the nondominant treated eyes, 89% achieved 20/50 or better monocular UDVA, 78% achieved 20/40 or better, and 34% achieved 20/32 or better. The binocular cumulative UDVA at 6 months postoperatively was 20/20 or better in all patients. All patients achieved J2 or better in binocular cumulative UNVA, and 83% achieved J1.
Conclusions:
Presbyopia correction using the combination of PresbyMAX in the near eye and aspheric monofocal regular LASIK in the distant eye is a safe and effective treatment for presbyopia in patients with myopia.
