1.What is posterior scleral reinforcement? Posterior scleral reinforcement, also known as posterior scleral pocket banding, posterior scleral support or posterior scleral strengthening, is the application of materials to reinforce the sclera at the posterior pole of the eye to stop or relieve the continuous dilatation of the posterior sclera. 2.What are the improvements of posterior scleral reinforcement? In order to improve the safety and effectiveness of posterior scleral reinforcement surgery, we have improved the surgical instruments, procedure and materials for posterior scleral reinforcement, and the materials were awarded the national invention patent (patent number: 201420207273). 3.What is the difference between the improved posterior scleral reinforcement surgery and the traditional posterior scleral reinforcement surgery? The improved surgery can make the posterior sclera fixed and contracted, which can be called posterior scleral reinforcement contraction surgery. 4.What are the clinical applications of PSRC? It is mainly used for the prevention and treatment of fundus lesions caused by the continuous growth of the pathological myopia axis, and is also an effective method to stop the continuous increase of myopia in pathological myopia. The treatment items include: control of high myopia deepening in children and adults, reset of macular cleft in high myopia eye, reset of macular cleft in high myopia eye, reset of macular detachment in high myopia eye, treatment of macular hemorrhage in high myopia eye, reset of macular cleft and retinal detachment in high myopia eye, reset of recurrent retinal detachment after high myopia ophthalmoplasty, silicone oil dependence and high intraocular pressure treatment after high myopia ophthalmoplasty, etc. 5.What are the advantages of PSRC for high myopia macular degeneration? This surgical method for the external eye is different from biosketch stripping silicone oil filling surgery, with less damage and no restrictive postoperative position, which usually does not cause serious complications such as cataract, glaucoma and corneal endothelial loss, and is not easy to recur. Visual acuity can generally be preserved and improved. 6.What are the common adverse effects of surgery? Visual deformation is common, mainly caused by the postoperative macular retinal folds, generally after half a year, the folds gradually subsided and the visual deformation gradually improved or disappeared. The occurrence of macular retinal folds is the evidence of posterior scleral contraction, which is also the key to the effectiveness of the surgery.
