The effectiveness and safety of modified posterior scleral reinforcement in Chinese children with high myopia

Background To evaluate the effectiveness and safety of modified posterior scleral reinforcement in controlling the progression of myopia in patients with high myopia and provide reference information on surgical treatment for these patients.Methods The study included 32 patients (55 eyes) with high myopia who were treated with modified posterior scleral reinforcement and were followed up at 3 months, 6 months, 1 year and 2 years after the operation.The axial length, refractive error, best corrected visual acuity (BCVA) and fundus colour photographs after the operation were compared with those before the operation, and whether there were any complications was recorded.Results The axial length of the eye increased by 0.07 mm, 0.12 mm, 0.31 mm and 0.19 mm at 3 months, 6 months, 1 year and 2 years after the operation, respectively. The refractive error increased by 0.05 D, 0.28 D, 0.53 D and 0.50 D at 3 months, 6 months, 1 year and 2 years after the operation, respectively, and the differences were not significant (P > 0.05). There were no statistically significant changes in BCVA, but there was an upward trend. No severe complications occurred.Conclusion Modified posterior scleral reinforcement can effectively delay the worsening of the ocular axis and refractive error, without severe complications in the short term.
