Presbyopia Correction Using The Presbymax Monocular Bi-Aspheric Ablation Profile In Myopic Eyes

To analyze the 6-month outcomes of a combination of the monocular bi-aspheric ablation profile and contralateral aspheric monofocal laser in-situ keratomileusis (LASIK) in myopia patients with presbyopia. 

Restrospective case series in Eyereum Eye Clinic and Yonsei University College of Medicine, Seoul, Korea. 

92 Patients (184 eyes) who underwent uneventful simultaneous bi-aspheric ablation in the dominant eye and aspheric monofocal regular LASIK in the non-dominant eye to correct myopia and presbyopia by a single surgeon between January 2017 and August 2020 were studied as a retrospective case review. Monocular and binocular near visual acuity (UNVA) and uncorrected distance visual acuity (UDVA), and corrected near visual acuity and near visual acuity were analyzed postoperatively.

The mean UDVA (logMAR) in the dominant and non-dominant eye was 0.01±0.02 and 0.26±0.15, respectively, at 6-months postoperatively. In addition, all treated dominant eyes achieved 20/20 or better monocular UDVA, and 84% achieved 20/16 or better monocular UDVA. In the non-dominant treated eyes, 89% achieved 20/50 or better monocular UDVA, 78% achieved 20/40 or better, and 34% achieved 20/32 or better. At 6-months postoperatively, the binocular cumulative UDVA was 20/20 or better in all patients. Of the patients, 83% achieved J1, and all patients achieved J2 or better in binocular cumulative UNVA. Of the non-dominant eyes, 86% maintained unchanged CDVA, 8% lost one line, and 2% lost two lines of CDVA in this 6-month period.

Performing presbyopic correction in patients with myopia using the monocular bi-aspheric ablation profile (PresbyMAX) in the near eye, combined with aspheric monofocal regular LASIK in the distant eye, resulted in safe and effective outcomes, which was comparble to the outcomes in patients with hyperopia.
