Abstract

Purpose

To evaluate the visual outcomes, visual performance, and stereoacuity in presbyopic patients following treatment by a change in the corneal asphericity and micro-monovision.

Methods

Presbyopic patients with diverse refractive errors and emmetropes (n = 30 eyes) were treated with a custom Q-ablation profile and micro-monovision in the non-dominant eye. There with a difference of Q − 0.30 in the Q profiles between dominant and non-dominant eyes. Patients were assigned in two groups based on the preoperative spherical equivalent (Group 1  + 4.00 to + 0.50, and group 2 neutral to − 3.00). Binocular uncorrected distance visual acuity (binocular UCVA), best-corrected visual acuity (BCVA), binocular uncorrected near visual acuity (binocular UNVA) preoperative and postoperative, spherical equivalent refraction, contrast sensitivity, and stereopsis were analyzed at 1, 3, and 6 months.

Results

The mean age was 52.6 ± 5.1 (SD) years. At six months post-operation, the mean binocular uncorrected distance visual acuity (binocular UDVA) was 0.15 ± 0.04 logMAR (20/25-) in group 1, and 0.11 ± 0.05 logMAR (20/25) in group 2, and binocular uncorrected near vision UNVA was 0.5 ± 0.1 M (20/25 J2) in group 1 and 0.45 ± 0.2 M (20/25 J2) group 2. An increase in stereoacuity was found in both groups.

Conclusions

The correction of refractive defects using customized corneal asphericity was an effective treatment in presbyopic patients. Furthermore, the treatment was well tolerated in this group of patients. Following surgery, the quality of vision was adequate, and the stereovision improved in this cohort of patients.
