Objective To evaluate the one-year results of LaserACE laser scleral surgery in the treatment of presbyopia. Methods This was a retrospective case study. LaserACE laser scleral surgery was performed on 16 eyes of 8 patients. The follow-up time was 12 months. Uncorrected near, intermediate and distance visual acuity (VA), near add, reading speed, spherical equivalent and intraocular pressure were measured at 1, 3, 6, and 12 months after surgery. The patients′ subjective experience was evaluated with the Catquest-9SF questionnaire. The data were analyzed with repeated measures analysis of variance and paired t test. Results All cases were uneventful. No patient lost BCVA lines after surgery. Mean binocular and monocular uncorrected near visual acuity (UNVA) increased significantly at 1, 3, 6 and 12 months after surgery (F=10.79, 26.64, P<0.01). Mean UNVA 12 months postoperatively improved from preoperative UNVA (P<0.05). Mean binocular and monocular uncorrected intermediate visual acuity (UIVA) increased after the surgery (F=5.11, 8.10, P<0.05). Mean binocular UIVA at 12 months postoperatively was not different from preoperative UIVA (P>0.05). No significant differences in binocular or monocular uncorrected distance visual acuity (UDVA) were detected postoperatively. Mean postoperative near add was significantly reduced (F=69.79, P<0.01). Mean reading speed was faster after the surgery (F=11.27, P<0.01). Conclusion LaserACE laser scleral surgery appears to improve intermediate and near visual acuity for presbyopic patients and has no effect on distance visual acuity postoperatively. It is safe and has the potential to improve patient intermediate and near vision over a 12-month follow-up period.
