摘      要：Background:To evaluate the effects on near and intermediate visual performance after bilateral Laser Anterior Ciliary Excision(LaserACE)***:LaserACE surgery was performed using the VisioLite 2.94μm erbium:yttrium-aluminum-garnet(Er:YAG)ophthalmic laser system in 4 oblique quadrants on the sclera over the ciliary muscle in 3 critical zones of physiological importance(over the ciliary muscles and posterior zonules)with the aim to improve natural dynamic accommodative *** was performed on 26 patients(52 eyes).Outcomes were analyzed using visual acuity testing,Randot stereopsis,and the CatQuest 9SF patient ***:Binocular uncorrected near visual acuity(UNVA)improved from+0.20±0.16 logMAR preoperatively,to+0.12±0.14 logMAR at 24 months postoperatively(p=0.0014).There was no statistically significant loss in distance corrected near visual acuity(DCNVA).Binocular DCNVA improved from+0.21±0.17 logMAR preoperatively,to+0.11±0.12 logMAR at 24 months postoperatively(p=0.00026).Stereoacuity improved from 74.8±30.3 s of arc preoperatively,to 58.8±22.9 s of arc at 24 months postoperatively(p=0.012).There were no complications such as persistent hypotony,cystoid macular edema,or loss of best-corrected visual acuity(BCVA).Patients surveyed indicated reduced difficulty in areas of near vision,and were overall satisfied with the ***:Preliminary results of the LaserACE procedure show promising results for restoring visual performance for near and intermediate visual tasks without compromising distance vision and without touching the visual *** visual function and visual acuity improvements had clinical *** satisfaction was high postoperatively and sustained over 24 months.
