Efficacy of PC-PRL implantation in the treatment of high myopia and its complications
Objective: To study the effect of implantable posterior chamber phakic refractive lens (PC-PRL) in the treatment of high myopia and its effect on naked eye vision and retinal complications. Methods: A total of 110 patients (220 eyes) with high myopia admitted to our hospital from June 2017 to Feb...

Methods: A total of 110 patients (220 eyes) with high myopia admitted to our hospital from June 2017 to February 2019 were selected as subjects. All patients were treated with PC-PRL implantation. The UCVA, BCVA, intraocular pressure, corneal endothelial cell count and intraocular lens position (anterior chamber depth and arch height) were compared before and after the treatment. Results: 6 months after treatment, 68.18% of patients had UCVA between 0.6 and 0.9, 31.81% of patients had UCVA of more than 1.0, and 100.00% of patients had BCVA of more than1.0. The BCVA and UCVA values of patients at 1 week, 1 month, 3 months and 6 months after operation were significantly greater than those before surgery (P<0.05). There were no significant differences in BCVA and UCVA among 1 week, 1 month, 3 months and 6 months after operation (P>0.05). The intraocular pressure was significantly greater than that of the preoperative one week after operation (P<0.05). There was no significant difference between the intraocular pressure at 1 month, 3 months and 6 months after operation (P>0.05). There was no significant difference in corneal endothelial cell count and arch height before and after treatment (P>0.05). The depth of anterior chamber at 3 months and 6 months after operation was significantly less than that before operation (P<0.05). There was no significant difference in the anterior chamber depth between 3 months and 6 months after operation (P<0.05). There were 7 cases of corneal edema, 4 cases of high pressure eyes, 2 cases of refractive regression within 6 months, and 1 case of near-difficulty within 1 month. The total complication rate was 12.73%. Conclusion: PC-PRL implantation is effective in the treatment of high myopia, which can improve the naked eye and correct vision. At the same time, the incidence of retinal complications is low, which can be promoted and applied clinically.http://www.hnykdxxb.com/PDF/202002/9.pdfhigh myopiapc-prl implantationnaked eye visionretinal complications |

June 2017 to February 2019 were selected as subjects. All patients were treated with PC-PRL
implantation. The UCVA, BCVA, intraocular pressure, corneal endothelial cell count and
intraocular lens position (anterior chamber depth and arch height) were compared before and
after the treatment. Results: 6 months after treatment, 68.18% of patients had UCVA between
0.6 and 0.9, 31.81% of patients had UCVA of more than 1.0, and 100.00% of patients had
BCVA of more than1.0. The BCVA and UCVA values of patients at 1 week, 1 month, 3 months
and 6 months after operation were significantly greater than those before surgery (P<0.05).
There were no significant differences in BCVA and UCVA among 1 week, 1 month, 3 months
