| Background: One typical cause of vision loss is myopia. It has already been observed that high myopia is becoming more and more common. The prevalence of myopia rose from 20.3% in 1990 to 28.3% in 2002, Purpose: This study aimed to compare the efficiency and safety of posterior scleral reinforcement and scleral collagen cross linkage in treatment of progressive myopia Patients and methods: A prospective study that was conducted on 40 eyes of 40 patients suffering from progressive myopia (24 males, 16 females). They were divided into two groups: The first group contained 20 eyes that underwent posterior scleral reinforcement. The 2nd group contained 20 eyes that underwent scleral collagen cross linkage Results: At the postoperative follow-up, we discovered that both groups' best corrected visual acuity (BCVA) had significantly improved from preoperative to postoperative measurements. In the first group, the BCVA improved in 15 eyes (75%) and stayed stable in five eyes (25%). In the second group, it improved in 13 eyes (65%) and was stable in seven eyes (35%). No postoperative patient's vision status had declined, according to any of the documents. At the last follow-up, BCVA performed noticeably better than it had before to the procedure. There were no statistically significant difference between gender and BCVA. Conclusion: In conclusion, the two management approaches were equally effective at slowing the progression of myopia and nearly equally effective at improving subjective symptoms. PSR, which directly reinforces the eyeball's wall mechanically, is crucial for slowing the growth of myopia, particularly in cases of high myopia. Scleral collagen cross linking is a safe and efficient way to avoid axial elongation and stabilize vision, but the first group's long-term impacts are still better. | ||||
