Primary multipoint (segmental) custom ablation.

Abstract

PURPOSE:

We present our experience in resolving visual symptoms in refractive patients undergoing primary multipoint (segmental) custom ablation.

METHODS:

Twelve eyes with mixed myopic astigmatism underwent evaluation and primary treatment by multipoint (segmental) custom ablation for the correction of refractive errors and visual symptoms using the Nidek NAVEX platform.

RESULTS:

Twelve eyes showed resolution of visual symptoms following diagnosis and treatment with MCA using the NAVEX platform. No patient lost two or more lines of best spectacle-corrected visual acuity. The postoperative root mean square of higher order aberrations did not change in a predictable or reproducible fashion.

CONCLUSION:

Multipoint (segmental) custom ablation with the Nidek NAVEX system was safe and effective for correcting mixed myopic astigmatism and for resolving visual symptoms in selected refractive surgery candidates. Small changes in the root mean square of higher order aberration values were not always reflected in a patient's subjective assessment of vision quality.
