Abstract Details
Purpose:
To evaluate the visual outcomes and stability up to 10-years following bilateral Laser Anterior Excision (LaserACE) for restoring dynamic near and intermediate vision.
Setting:
Prospective single arm clinical study, Chang Gung Memorial Hospital, Linkou Taiwan.
Methods:
An Er:YAG laser was used in 4 quadrants on the sclera to improve pliability & biomechanical efficiency of the ciliary muscles in 3 critical zones, for 24 patients. Patients were over 40 years of age and showed loss of accommodative ability. Three patients were evaluated Visual outcomes were assessed using the Early Diabetic Retinopathy Study [EDTRS] logMAR charts at 1, 3, 6, 12, and 24 months for all patients, and after 10 years for 3 patients.
Results:
At 24 months postoperatively, distance corrected near visual acuity (DCNVA) was 20/30 or better in 83% of subjects; 67% 20/25 and 50% 20/20, uncorrected near visual acuity (UNVA) was 20/30 or better in 83% of subjects; 78% 20/25 and 33% 20/20. These improvements were stable over 10 years. Corrected distance visual acuity (CDVA), distance corrected intermediate visual acuity (DCIVA), and DCNVA for all patients remained at 20/20 or better after 13 years postoperatively. There was no statistical change in DCVA or UDVA. Mean stereopsis improved from 75.77” to 60”.
Conclusions:
LaserACE performed using the VisioLite Er:Yag laser appears to be a safe and effective procedure for restoring range of visual performance. LaserACE provided improvement in near vision functionality in these patients with long-term stability, and without compromising UDVA, CDVA, or binocularity. The LaserACE procedure is not on the visual axis, therefore these patients could still receive correction.
