Visual quality after presbyopia correction with excimer laser ablation using micromonovision and modulation of spherical aberration.

PURPOSE: To evaluate the quality of vision after excimer laser (MEL 80) correction of presbyopia using micromonovision and aspheric aberration patterns.

SETTING: Hospital Universitario QuirónSalud, Madrid, Spain.

DESIGN: Prospective case series.

METHODS: Patients were assigned to 1 of 3 groups based on the preoperative spherical equivalent. Visual acuity, spherical aberration, contrast sensitivity, quality of vision, and safety of the procedure were assessed preoperatively and at the end of the study. The dominant eye was treated for distance vision and the nondominant eye for near vision, with modulation of spherical aberration.

RESULTS: The study comprised 50 patients (100 eyes). The mean patient age was 46.84 years ± 4.17 (SD). Stereopsis at the end of the study improved in Group 3, from 215.29 ± 99.63 seconds of arc (arcsec) and 169.41 ± 71.10 arcsec (P = .025); no changes were seen in the other groups. Contrast sensitivity at 18 cycles per degree increased in Group 2 (P = .021), with no changes in the other groups. Group 1 and Group 2 had the best optical quality of vision after the surgery based on Optical Quality Analysis System frequency of the modulation transfer function values of 100%, 20%, and 9% and the Strehl ratio.

CONCLUSION: The correction of presbyopia by micromonovision and aspheric aberration ablation with an excimer laser led to minimal changes in stereopsis, contrast sensitivity, and optical quality.
