AIM:To present a technique of transcapsular scleral fixation of the standard capsular tension ring(CTR)through equatorial capsulotomy and in-the-bag intraocular lens(IOL)implantation in subluxated lenses.METHODS:This retrospective consecutive case series included patients with subluxated lenses by more than 180 degrees who underwent lens extraction,transcapsular scleral fixation of the standard CTR through equatorial capsulotomy,in-the-bag IOL implantation and with at least 6mo follow-up.Preoperative and postoperative best corrected visual acuity(BCVA),intraocular pressure(IOP),complications,and postoperative IOL tilt and decentration were recorded.RESULTS:Nine eyes of 7 patients with a mean followup of 11.0±3.7mo were included in this study.The BCVA was significantly improved from 0.64±0.22 logMAR preoperatively to 0.21±0.19 logMAR postoperatively(P<0.001).The IOP was within the normal range postoperatively.The mean tilt of the IOL was 4.30°±2.31°(range,1.0°to 8.9°)and the mean decentration of the IOL was 0.37±0.12 mm(range,0.14 to 0.50 mm).No visually threatened intraoperative and postoperative complications were detected during the follow-up period.CONCLUSION:This is a safe and effective surgical technique for managing patients with severely subluxated lenses.It has achieved favorable outcomes with fewer surgical manipulations and less need for advanced capsular support devices. 展开更多

AIM:To compare the rotational stability of Toric intraocular lens(IOLs)implantation combined with foureyelet or two-eyelet capsular tension rings(CTRs)in eyes with high myopia and cataract.METHODS:This prospective randomized controlled interventional study in cluded 33 eyes which had preoperative corneal astigmatism≥1.5 D and ocular axial length≥25.5 mm.These eyes were randomly divided into two groups to undergo phacoemulsification and toric IOL implantation with either four-eyelet CTR implantation(group A,n=16)or two-eyelet CTR implantation(group B,n=17).Uncorrected visual acuity(UCVA),best-corrected visual acuity(BCVA),phoropter examination results,and toric IOL rotation degrees were tested 6 mo after the surgery.RESULTS:In both groups,the toric IOL was in the capsular sac 6 mo after surgery.The difference between the two groups in terms of visual outcome was not found to be statistically significant(P>0.05)at a follow-up of 6 mo.The mean residual astigmatism values were 0.56±0.22 D and 0.92±0.24 D in A and B groups,respectively(P<0.001).The mean rotation degree of IOL was 1.00°±0.73°in group A and 3.53°±1.46°in group B(P<0.001).CONCLUSION:In cataract patients with high myopia and astigmatism,four-eyelet CTR can effectively increase the rotation stability of toric IOLs,achieving the desired goal of correcting corneal astigmatism. 展开更多

AIM:To investigate the effect of Cionni-modified capsular tension ring(CTR)implantation in patients with severely traumatic subluxated cataracts.METHODS:All patients who totally had traumatic cataracts and lost zonule support and underwent cataract surgery were retrospectively analyzed.Corrected distance visual acuity(CDVA),extent of zonulysis,intraocular lens(IOL)position,intraoperative presentation,and complications were assessed.The primary outcomes included IOL centration stability and other postoperative complications.RESULTS:Twenty patients(20 eyes)were included in this study.The mean age in this study was 58.0±11.3y,and the average follow-up time was 17.3±12.8mo.Capsule bags were saved by Cionni-modified CTR.Nine eyes(45%)underwent simultaneously anterior vitrectomy due to the presence of vitreous in the anterior chamber.The preoperative mean CDVA was 0.83±0.24 log MAR,and the postoperative average CDVA was 0.23±0.30 log MAR(P<0.05).The horizontal and vertical IOL decentration after surgery was 0.27±0.12 mm and 0.41±0.19 mm,respectively;the vertical and horizontal IOL tilt after surgery was 5.5°±2.5°and 6.1°±2.2°,respectively.None of the eyes had obvious IOL decentration during the follow-up time.Eight eyes(40%)had posterior capsule opacification(PCO)that was severe enough to cause poor vision.Neodymium:YAG laser capsulotomy were performed on these eyes when the CTR was stabilized.CONCLUSION:With the help of Cionni-modified CTR,capsular bag preservation and better IOL concentration can be achieved without major complications in patients with severely traumatic subluxated cataracts. 展开更多

To evaluate the safety and stability of capsulotomy, changes in the size of posterior capsulotomy and anterior chamber depth(ACD) in three groups: the group without CTR, the group with 12 mm CTRs, and the group with 13 mm CTRs, at 1wk, 3, 12, and 15mo after capsulotomy, were compared. ·RESULTS: In the group without CTR and the group with 12 mm CTR, there was no significant change in ACD at every post-laser follow-up. In the group with 13 mm CTR, the ACD change was significant until 3mo after capsulotomy. In all groups, there was a significant increase in the area of capsulotomy between 1wk and 3mo post-laser. Between 3 and 12mo post-laser, only the group with 13 mm CTR showed a significant increase in the area of capsulotomy(P<0.01). ·CONCLUSION: Laser posterior capsulotomy is safe in all three groups. The capsulotomy and ACD become stabilized and have not shown significant changes since 1y postlaser, even with larger CTRs. The maintenance of centrifugal capsular tension can last longer with larger CTRs, and the stability of the capsulotomy site can be reached about 12mo after capsulotomy in pseudophakic eyes with larger CTRs. 展开更多

Background:To evaluate the efficacy and safety of placing dual capsular tension rings for the combined management of traumatic cyclodialysis cleft and zonular dialysis.Methods:A modified capsular tension ring was inserted into the ciliary sulcus and a capsular tension ring or modified capsular tension ring was inserted into the capsular bag in 20 eyes in 20 consecutive patients showing signs of ocular hypotony and ectopia lentis.Outcome measures included intraocular pressure,best-corrected visual acuity,and postoperative complications.Results:Dual capsular tension ring placement was performed in 20 patients with a mean age of 48.7 years.The cyclodialysis cleft extended over 2.9 clock hours(range 0.5-6.5).The modified capsular tension ring was successfully inserted into the ciliary sulcus and a capsular tension ring or modified capsular tension ring in the capsular bag in all eyes.At the last follow-up,the cyclodialysis cleft was closed in 16/20(80.0%)eyes.The intraocular lens was stable in all patients postoperatively.Best-corrected visual acuity,in terms of the logarithm of the minimal angle of resolution,improved from 1.3±0.8 before surgery to 0.4±0.3 after surgery(P<0.001).Intraocular pressure increased significantly from 10.6±3.2 mmHg before surgery to 13.0±4.8 mmHg after surgery(P=0.040).Postoperative complications included a painful reversible intraocular pressure spike in four patients(20.0%).Logistic regression revealed no significant factors associated with successful cleft closure and a stable final intraocular pressure of≥10 mmHg.Conclusions:The placement of two capsular tension rings into the ciliary sulcus and the capsular bag is a safe,successful procedure combined for repairing a traumatic cyclodialysis cleft and managing zonular dialysis. 展开更多

Posterior capsular opacification(PCO)is the leading cause of vision loss after cataract,mainly caused by the adhesion,proliferation and trans-differentiation of post-operative residual lens epithelial cells(LECs).Effective PCO prevention remains a huge challenge to ophthalmologists and researches for decades.Herein,we developed a“NIR-triggered ROS storage”intraocular implant(CTR-Py-Pp IX)based on capsular tension ring(CTR),which is concurrently linked with photosensitizer protophorphyrin IX(Pp IX)and energy storage2-pyridone derivative(Py),to guarantee instantaneous and sustainable ROS generation for LECs killing,aiming to achieve more efficient and safer photodynamic therapy(PDT)to effectively prevent PCO.The silylated Pp IX-Si and Py-Si were covalently conjugated to the plasma activated CTR surface to obtain CTR-Py-Pp IX.Results demonstrated that CTR-Py-Pp IX had dual functions of PDT and battery,in which Pp IX could generate ROS extracellularly under irradiation,with one part directly inhibiting LECs by lipid peroxidation(LPO)induction of cell membranes.Meanwhile,the excess ROS stored in Py could be continuously released to amplify LPO levels after the irradiation was removed.Ultimately,the proliferation of LECs in capsular bag was completely inhibited under mild irradiation conditions,achieving a sustainable and controlled PDT effect for effective PCO prevention with good biocompatibility.This NIR-triggered ROS storage intraocular implant would provide a more efficient and safer approach for long-term PCO prevention. 展开更多
