Abstract:
Objective To explore the influencing factors of visual acuity recovery in patients with high myopia after posterior chamber phakic intraocular lens(ICL)implantation.Methods A prospective study was conducted on 210 pa-tients(420 eyes)with high myopia who underwent ICL implantation at the Second Affiliated Hospital of Zhengzhou Univer-sity from May 2021 to March 2023.The patients were divided into a good recovery group[best corrected visual acuity(BC-VA)recovery ≥0.3 D]and a poor recovery group(BCVA recovery＜0.3 D)based on their visual acuity recovery status three months after surgery.The baseline data of patients in the two groups were compared,and the factors affecting visual acuity recovery were analyzed using Logistic regression.The receiver operating characteristic(ROC)curve was used to an-alyze the predictive value of the Logistic regression model for poor visual acuity recovery in patients with high myopia after ICL implantation.Results Three months after surgery,149 patients(298 eyes)were in the good recovery group,and 61 patients(122 eyes)were in the poor recovery group.There were no significant differences in gender,age,years of myopi-a,body mass index,and academic performance between the two groups(all P＞0.05).The proportions of patients with corneal astigmatism＜1.30 D(55.74％),corneal diopter＜45 D(59.02％),Pittsburgh Sleep Quality Index(PSQI)＜7 points(63.93％),and average central radius of curvature[(7.82±0.27)mm]in the poor recovery group were lower than those in the good recovery group[83.89％,81.88％,85.91％,and(7.90±0.24)mm,respectively].The central flat me-ridian curvature(k1)of the anterior corneal surface[(43.27±1.43)D],steep meridian curvature(k2)of the anterior corneal surface[(44.84±1.53)D],and arch height[(628.49±67.28)μm]in the poor recovery group were higher than those in the good recovery group[(42.73±1.42)D,(44.12±1.47)D],and[(417.56±80.14)pm],with significant differences(all P＜0.05).Logistic regression analysis showed that corneal astigmatism,corneal diopter,k1,k2,arch height,and PSQI score were independent influencing factors of poor visual acuity recovery after ICL implantation in pa-tients with high myopia(all P＜0.05).ROC curve analysis showed that the area under the ROC curve for predicting poor visual acuity recovery after ICL implantation in patients with high myopia by Logistic regression model was 0.938(95％CI:0.896-0.966),the sensitivity was 83.61％,and the specificity was 91.95％(P＜0.05).Conclusion The visual acuity recovery after ICL implantation in patients with high myopia is affected by corneal astigmatism,corneal diopter,k1,k2,arch height,and PSQI score.The Logistic regression model based on these factors has high predictive value for visual acui-ty recovery after ICL implantation.
