Objective: To evaluate the changes of visual fatigue symptoms, accommodative functions, ocular surface conditions, and high-order aberrations (HOA) after implantation of Implantable Collamer Lens (ICL), and explore their effects on asthenopia. Methods: Design: prospective observational case series. Patients with ametropia who underwent ICL surgeries and completed 3-month follow-up periods in our hospital were enrolled. Asthenopia degrees, amplitude of accommodation (AA), positive/negative relative accommodation (PRA/NRA), accommodative facility (AF), the ratio of accommodative convergence and accommodation (AC/A), Schirmer I test, noninvasive breakup time (NBUT), and HOA were examined and analyzed preoperatively and at 1 week,1 month and 3 months postoperatively. Results: Symptoms of asthenopia: the symptoms of asthenopia were significantly worse at 1 week after ICL surgeries than those before surgeries but increased gradually as time went by. The asthenopia scores 1 month after surgeries were still higher than those before ICL surgeries, eventually recovered at 3 months postoperatively. AA, AF, AC/A decreased 1 week postoperatively, returned to the baseline at 1 month and were higher at 3 months after surgeries. NBUT at 1 week, 1 month and 3 months after surgeries were significantly decreased and was the lowest at 1 week postoperatively. PRA, NRA, Schiermer values and HOA had no significant change. 3. Correlation analysis showed that the worse AF and NBUT, the more severe the symptoms of asthenopia. Conclusion: The symptoms of asthenopia aggravate transiently after ICL implantation surgeries, but improved gradually with time. AF and NBUT were important factors affecting the changes of asthenopia.
