    Co-Authors: Min Zhang, Michael Deng, Tianhui Chen, Zexu Chen, Yongxiang Jiang
    Abstract:

    PURPOSE To investigate the accuracy of intraocular Lens (IOL) formulas for the prediction of postoperative refraction in Lens Subluxation in Marfan syndrome. SETTING Eye and ENT Hospital of Fudan University, Shanghai, China. DESIGN Consecutive retrospective clinical observational case series. METHODS 60 eligible eyes with Lens Subluxation from 39 young patients with Marfan syndrome (8.53 ± 4.38 years) underwent phacoemulsification combined with single-eyelet modified capsular tension ring (MCTR) and IOL implantation. The prediction error values with mean zero out (relative prediction error) and their absolute values (AE) were calculated. RESULTS Generally, the SRK/T formula with Wang-Koch (WK) adjustment had the lowest median AE at 0.418 diopters (D), and the Holladay 1 with WK adjustment had the lowest mean AE at 0.499 D. The median AE of the other 10 formulas, in order from lowest to highest, were Haigis with WK (0.494 D), Holladay 1 with WK (0.495 D), Hoffer Q with WK (0.508 D), Haigis (0.525 D), T2 (0.542 D), Hoffer Q (0.624 D), SRK/T and Holladay 1 (0.660 D), Super (0.680 D), and Barrett Universal II (0.714 D) formulas. Haigis formula was found to be statistically significantly different from SRK/T, Holladay 1, and Barrett Universal II (all 3 P < .001) but not Hoffer Q (P = .236) formula. CONCLUSIONS The Haigis formula was recommended for young Marfan Lens Subluxation patients with in-the-bag IOLs and scleral-sutured single-eyelet MCTR implantation. WK adjustments were successful in those cases where the axial length was longer than 25.0 mm.

  • visual outcomes of Lens Subluxation surgery with cionni modified capsular tension rings in marfan syndrome
    Scientific Reports, 2021
    Co-Authors: Tianhui Chen, Jiahui Chen, Michael Deng, Min Zhang, Zexu Chen, Yongxiang Jiang
    Abstract:

    Marfan syndrome (MFS) is a hereditary disease with an incidence of 0.3% in the general population. Approximately 60% of MFS patients with FBN1 gene mutation will suffer ectopia lentis (EL) from the age of 3. With the development of EL, severe loss of vision will accrue because of Lens tilt and glaucoma. Cionni modified capsular tension rings (MCTR) has been applied in the surgery for EL in MFS patients. To evaluate visual acuity and safety of using MCTR during Lens Subluxation surgery in MFS patients, 66 MFS patients (110 eyes) were included in our study, with the mean duration of follow-up of 4.7 months (SD 1.76 months). The capsular bags were preserved in 101 eyes (91.81%) with MCTR implantation. There was an overall significant improvement in BCVA at 1-month follow-up which was maintained at 3 months. Multivariable linear regression revealed that older age at first visit was associated with greater postoperative BCVA at the 1-month follow-up (P = 0.007). A significant difference was found between different degrees of Lens Subluxation and the length of surgical time and complications. At follow-up, only two eyes (1.98%) were identified to have developed retinal detachments. In conclusion, better visual outcomes can be achieved when patients received an early operation with MCTR implantation.

  • Corneal Curvature, Astigmatism, and Aberrations in Marfan Syndrome with Lens Subluxation: Evaluation by Pentacam HR System
    Scientific Reports, 2018
    Co-Authors: Jiahui Chen, Qinghe Jing, Yating Tang, Dongjin Qian, Yi Lu, Yongxiang Jiang
    Abstract:

    Marfan syndrome (MFS) is associated with abnormalities of corneal biometric characteristics. We conducted a retrospective case-control study including 55 eyes of the MFS patients with Lens Subluxation and 53 normal eyes of the control subjects to evaluate the corneal curvature, astigmatism and aberrations using a rotating Scheimpflug camera (Pentacam HR). Compared with the control group, the anterior, posterior, and total corneal curvature were flatter in the MFS group. The anterior and total corneal astigmatism were higher in the MFS patients, whereas the posterior corneal astigmatism was not significantly different between the two groups. Regarding the total corneal aberrations, the root mean square (RMS) aberrations, RMS higher-order aberrations and RMS lower-order aberrations increased, whereas the spherical aberration decreased in the MFS patients. Corneal parameters had potential diagnostic values for MFS patients with Lens Subluxation and the more reasonable cutoffs were the values of corneal curvature 0.85 D and spherical aberration

Corneal biometric characteristics of MFS patients with Lens Subluxation include decreased corneal curvature, higher corneal astigmatism, larger corneal aberrations, and lower spherical aberration. Corneal curvature, corneal astigmatism, and spherical aberration are better diagnostic tools for suspicious MFS.

  • research progress on surgical management of Lens Subluxation
    Int Rev Ophthalmol, 2017
    Co-Authors: Jiahui Chen, Qinghe Jing
    Abstract:

    The surgical treatment is the main management for Lens Subluxation at present. In recent years, to retain and remodel the septum of the capsular bag and zonule to the fullest extent, some novel capsular auxiliary devices, such as capsular retractors, capsular tension rings, capsular tension segements, capsular anchors, and the femtosecond laser-assisted cataract surgery have been used, which makes the operation safer and leads to less postoperative complications. When treating patients with Lens Subluxation, the preoperative clinical evaluation, the selection of surgical approaches, the use of intraoperative equipment, and the implantation of intraocular Lens (IOL) need to be considered comprehensively by ophthalmic surgeons. In order to obtain the best effect of surgical management, surgeons should try to reduce the intraoperative and postoperative complications as much as possible, and maintain the stability of the capsular bag and IOL.(Int Rev Ophthalmol, 2017, 41: 101-105) Key words: Lens Subluxation; capsular tension devices; phacoemulsification

    Abstract:

    AIM:To investigate the safety and effect of femtosecond laser-assisted cataract surgery with Cionni modified capsular tension ring(MCTR)implantation in the management of traumatic Lens Subluxation.METHODS: Totally 11 patients(11 eyes)with traumatic Lens Subluxation were divided into three groups according to the severity of Lens dislocation, ranging from 90° to 120°(4 eyes), 120° to 180°(5 eyes)and 180° to 270°(2 eyes). The contact Lensx femtosecond laser cataract surgery platform was applied to create the capsulotomy, prepare nuclear fragmentation and make corneal wound creation. Anterior vitrectomy was performed in some patients during the surgery. After capsular retractors insertion and phacoemulsification, the MCTR was inserted to the capsular bag and fixed to the sclera. Finally, the IOL was implanted into the capsular bag. Postoperative visual acuity, intra- and post-operative complications, anterior capsular opening, IOL and MCTR position and intraocular pressure(IOP)were assessed.RESULTS:The duration of follow-up was 2mo. All the operations were completed successfully. Five eyes underwent cataract surgery combined with anterior vitrectomy. Four eyes had been inserted with 2-eyelet MCTR and seven eyes with 1-eyelet MCTR. The best corrected visual acuity(BCVA)after operation was better than 0.5 in 4 eyes, between 0.3 and 0.5 in 3 eyes, between 0.1 and 0.3 in 3 eyes, and less than 0.1 in 1 eye. Compared with preoperative BCVA, the difference was statistically significant(P
