Abstract:
Objective To investigate the efficacy of phacoemulsification combined with intraocular lens implantation in the treatment of retinitis pigmentosa complicated with cataract.Methods A retrospective study was conducted in 52 patients (101 eyes) who admitted in Leshan People's Hospital from January 2012 to December 2016 after diagnosed with primary retinitis pigmentosa combined with cataract and underwent phacoemulsification combined with intraocular lens implantation,and then the clinical data were retrospectively analyzed.All patients were examined for the best corrected visual acuity (BCVA),intraocular pressure,slit lamp anterior segment examination,fundus examination under cycloplegia and optical coherence tomography before and after treatment.The preoperative and postoperative variables were compared by paired t-test,and the correlation between visual acuity and the macular thickness was analyzed by Pearson correlation test.Results Cataract surgery was completed successfully,and all patients were followed-up for (3-12) months,with an average (5.09 ± 2.20) months.The average BCVA of 101 eyes was increased from (0.12 ± 0.09)before surgery to (0.21 ± 0.16) after surgery,and the difference was statistically significant (t =-8.016,P =0.000).Postoperative visual acuity was significantly correlated with macular thickness.Furthermore,there was a negative correlation of macular thickness with macular cystoid edema,macular epiretinal membrane and visual acuity (r =-0.866,P =0.001),but a positive correlation with macular atrophy (r =0.928,P =0.000).Unfortunately,anterior capsule contraction occurred in 2 eyes after cataract surgery,and secondary intraocular hypertension appeared in 2 eyes.Visual acuity was improved and stable for a long time after radial incision of anterior capsule and medication control of intraocular pressure.Conclusion Phacoemuisification combined with intraocular lens implantation can improve the vision of patients,and is a safe and effective method for the treatment of retinitis pigmentosa complicated cataract.
