Abstract Details


To evaluate accommodative benefits for near and intermediate visual performance after bilateral LaserACE procedure. Stereoacuity and patient satisfaction are also assessed.


: A prospective single arm design clinical study .


LaserACE procedure was performed on 15 patients bilaterally. Results over 12 months were captured. Outcomes of 15 Subjects ≥40 years of age with a demonstrated loss of accommodative function that had good uncorrected distance vision with less than 1.0D of refractive astigmatism and otherwise healthy eyes we examined. Primary study targets were Binocular Defocus Curve and Unaided Near and Intermediate Visual Acuity with a secondary target of Stereoacuity and Patient Reported outcome Questionnaire. LaserACE procedure was performed using the VisioLite Er:YAG ophthalmic laser system. Results were also analyzed by iTracey objective wavefront aberrometry.


All patients achieved some improvement of Near & Intermediate Vision. An average of 4 lines of improvement of reading vision was seen with an average of 1.5D added accommodative reading power after the procedure. Patient satisfaction was in the 90th percentile for the patient group and stereoacuity was unaffected by the procedure


LaserACE procedure with VisioLite Er:YAG laser appears to be a safe and effective procedure for restoring range of visual performance for near and intermediate visual tasks. Average added accommodative power was approximately 1.5D which had clinical significance. Patient satisfaction was high post operatively and sustained over 6-12 months in this group.
