To investigate the effects and safety of a novel posterior scleral reinforcement (PSR) in the treatment of pathological myopia.
This study included 34 highly myopic eyes of 19 patients who underwent a novel PSR. Axial length, refractive error, best corrected visual acuity (BCVA), macular scans and the incidence of complications were recorded at baseline and examined postoperatively at yearly intervals for three years.
The mean value of axial elongation was 0.55±1.01mm over the 3 years, approximately 0.18mm per year, similar to the findings in normal schoolchildren(0.25 mm per year). There was no significant difference in refractive error before and after the surgery in the 3-years visit(P=0.548).The postoperative refractive error almost maintained stable with a mean change of +0.28±1.60D, during the 3 years after the surgery. Statistical results showed significant differences in best corrected visual acuity (BCVA) between the pre-operation and postoperative status during the 3 years(P=0.006). Among them, the BCVA improved in 29 eyes(82.86%), remained stable in 5 eyes(14.29%) and there were no records of visual decline in any postoperative patient. There were no serious complications during the 3 year follow-up period.
The novel PSR is a safe and effective treatment in controlling the pathological process of pathological myopia.
