Abstract Objective: To analyze the changes of visual function and quality of life in the first eyes versus the second eyes with high myopia before and after cataract surgery, to provide a theoretical basis for cataract surgery for the second eyes with good vision. Methods: In this prospective clinical study, 48 bilateral highly myopic patients (axial length ≥ 27.0 mm, myopia exceeding-6.00 diopters) who underwent uneventful sequential cataract surgery (the eyes with worse visual acuity operated first) in Xi'an People's Hospital (Xi'an Fourth Hospital) from June 2019 to June 2020 were collected, the time interval between the first eyes and second eyes was 2-4 weeks.The visual acuity, visual function (VF) and quality of life (QOL) questionnaire was completed before the surgery, 1 week and 3 months after surgery, respectively. Objective scattering index (OSI) and modulation transfer function cutoff frequency (MTF cutoff) were compared by doublepass optical quality analysis system (OQAS-II) at each time point. Differences in the parameters were compared between the first and second eyes using independent t test. Results: The first eyes' postoperative BCVA logMAR was 0.20±0.35, the spherical equivalent (SE) was-2.42±0.84 D and the second eyes preoperative SE was -19.30±4.65 D, BCVA logMAR was 0.57±0.29. VF questionnaire showed that the subjective visual quality, peripheral visual field, visual adaptation and stereoscopic function scores were significantly improved after the first eyes' surgery (t=-16.16, -18.65, -9.79, -9.94, all P<0.001), and these four functions were further improved after the second eyes' surgery (t=-34.32, -14.87, -15.95, -21.36, all P<0.001), the peripheral visual field and stereopsis function were further improved after 3 months of the surgery for both eyes compared with 1 week after surgery of the second eyes (t=-2.27, P=0.030; t=2.37, P=0.020). QOL questionnaire showed that the patients' scores of self-care ability, activity ability, social ability and psychological status scale were significantly improved after the first-eye surgery compared with those before surgery (t=-31.52, -21.79, -19.68, -14.16, all P<0.001). Only the score of psychological status was improved significantly after the second-eyes cataract surgery compared with that after the first-eyes' surgery (t=-12.50, P<0.001). OQAS-II showed that the OSI values of the first and the second eyes were significantly lower at 1 week and 3 months postoperatively when compared with the preoperative values (t=17.15, -19.54, 9.61, 10.18, all P<0.001) and MTF cutoff value was significantly higher than that before surgery at 1 week and 3 months postoperatively (t=10.58, -11.65, -8.23, -9.15, all P<0.001). Conclusions: Cataract surgery of the first eyes can significantly improve the quality of life for the patients with high myopia, while second eyes surgery may significantly further improve visual function and quality of life especially the psychological status for cataract patients with high myopia.
