Effect of lens capsular tension ring on preventing capsular contraction syndrome in the surgery of retinitis pigmentosa combined with cataract: Retrospective case series

Abstract

Retinitis pigmentosa (RP) is a clinically common congenital retinal disease, with an incidence of about 1/4000. 1 The pathological manifestations include progressive dysfunction of retinal pigment epithelial cell and photoreceptor cell, and patients tend to be night blind and have reduced vision field and poor vision. Currently, there is no effective treatment or prevention measures for RP, and interventions such as stem cell transplantation and gene therapy are still in the research stage. 2,3 In addition to primary retinal damage, RP is usually accompanied by other eye diseases. Cataract is one of the most common complications of RP. 4 Patients with RP complicated with cataract are young in age and progress rapidly, which has a great impact on the remaining vision of patients, and usually, patients would need surgical treatment. This paper retrospectively analysed the vision, intraocular pressure (IOP), corneal endothelial cell count (ECC), macular morphology and postoperative complications of 63 patients (84 eyes) who underwent phacoemulsification

Effects and Prognosis of Cataract Surgery in Patients with Retinitis Pigmentosa

“…One Chinese article [13] was excluded because of insufficient data (no duration of follow-up) and two English articles were excluded because the results had been repeatedly reported by the same research group [14,15]. The remaining 16 studies [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] were included for data analysis. The flowchart of the selection process is shown in Fig.…”

Exploring anterion capsular contraction syndrome in cataract surgery: insights into pathogenesis, clinical course, influencing factors, and intervention approaches

“…This helps to maintain the effective position and stability of the IOL, improve higher-order aberrations, and enhance visual quality ( 91 ). Therefore, we recommend the intraoperative implantation of CTR for cataract patients who have risk factors, as a preventive measure against postoperative ACCS ( 30 , 92 ). For instance, a retrospective study conducted on patients undergoing cataract surgery with RP revealed that the incidence of ACCS was lower in those who received CTR implantation compared to those without CTR ( 93 ).…”

Retinitis Pigmentosa: Current Clinical Management and Emerging Therapies

“…Furthermore, higher rates of posterior capsular opacification and anterior capsule phimosis have been described following cataract surgery in patients with RP, which may also negatively influence visual outcomes if left untreated [ 178 ]. Despite the challenges regarding cataract surgery in RP, several studies have demonstrated its benefit, showing average BCVA improvements between studies ( Table 1 ) [ 105 , 162 , 178 , 179 , 180 , 181 , 182 , 183 , 184 , 185 , 186 ]. Subjectively, visual improvement was reported in 44.8–96.7% of patients included in these studies [ 177 ].…”

“…Large capsulorrhexis can assist with optimal maneuvering, while also reducing the risk of capsular phimosis. The use of a capsular tension ring may also provide stability and decrease the risk of IOL (sub)luxation and anterior capsular phimosis, although the insertion itself of the capsular tension ring may also cause strain on the lens zonule system, so prophylactic insertion of such a ring may not be indicated [ 177 , 182 ]. IOL (sub)luxation at short- or long-term follow-up in RP has been reported in several case studies, and these cases were managed using scleral suture fixation or by replacing them with a range of anterior chamber IOLs after the (sub)luxated IOL had been removed, often requiring accompanying vitrectomy [ 191 , 192 , 193 ].…”
