Trypan blue capsular staining to “find” the leading edge of a “lost” Capsulorhexis
American Journal of Ophthalmology, 2002Co-Authors: Peter W.t De Waard, Camille J. Budo, Gerrit R. J. MellesAbstract:Abstract PURPOSE: To describe an effective surgical technique to visualize an obscured leading edge of a Capsulorhexis. DESIGN: Prospective, interventional case series. METHODS: In six eyes of six patients in which the Capsulorhexis was started but could no longer be seen during surgery, the anterior chamber was irrigated to remove all viscoelastic, and 0.3-ml trypan blue 0.06% was applied onto the anterior lens capsule to stain and visualize the leading edge of the Capsulorhexis. RESULTS: In all patients, the leading edge of the Capsulorhexis was quickly visualized by using the dye. No adverse reactions were observed up to 1 year after surgery. CONCLUSION: Trypan blue staining of the anterior lens capsule is an effective and apparently safe technique to “find” a “lost” Capsulorhexis during surgery.

Trypan blue capsule staining to visualizethe Capsulorhexis in cataract surgery
Journal of Cataract & Refractive Surgery, 1999Co-Authors: Gerrit R. J. Melles, Peter W.t De Waard, Jan H. Pameyer, W. Houdijn BeekhuisAbstract:A Capsulorhexis may be difficult to perform in the absence of a red fundus reflex. Using 0.1 mL of trypan blue 0.1% to stain the anterior capsule in 30 patients with a mature cataract enabled us to visualize the Capsulorhexis during phacoemulsification. No adverse reactions were observed up to 12 months after surgery. Trypan blue staining of the anterior capsule appears to be a safe technique to facilitate the performance of a Capsulorhexis in the absence of a red fundus reflex.

lens capsule related complications of femtosecond laser assisted capsulotomy versus manual Capsulorhexis for white cataracts
Journal of Cataract and Refractive Surgery, 2019Co-Authors: Xinyi Chen, Peiqing Chen, Wen Xu, Xingchao Shentu, Yibo YuAbstract:Purpose Comparison of lens capsule-related complications resulting from femtosecond laser–assisted capsulotomy and manual Capsulorhexis in patients with white cataracts. Setting Eye Center, Second Affiliated Hospital, Zhejiang Medical School, Hangzhou, China. Design Prospective consecutive nonrandomized comparative cohort study. Methods Selected patients were divided into a femtosecond laser–assisted cataract surgery group (FLACS group) and a conventional phacoemulsification cataract surgery group (CPCS group). Each case was recorded as either a type I or type II white cataract. Here, type I was characterized by the presence of a liquefied cortex, whereas type II had a solid cortex. Five experienced phacoemulsification surgeons conducted all surgeries. Lens capsule-related events, including anterior capsule tears, posterior capsule ruptures (PCRs), incomplete capsulotomies, and irregular capsulorhexes were recorded; surgical parameters, postoperative visual acuities, and intraocular lens (IOL) decentrations were evaluated. Results The study comprised 132 eyes of 132 patients (66 in each group). Anterior capsule tears were significantly more common in the CPCS group than the FLACS group (12.1% versus 0%). All 8 cases of anterior capsule tears were type I cases. Six FLACS cases developed incomplete capsulotomies, four of which were type I cases. The incidences of PCRs and vitreous loss were the same. Capsulotomy produced better circularity index and diameter stability than Capsulorhexis. IOLs were better centered in the FLACS group than the CPCS group. The mean ultrasound power, absolute phaco time, effective phaco time, and postoperative visual acuities were similar in both groups. Conclusions Compared with CPCS, FLACS decreased the risk for anterior capsule tears in white cataracts, especially in type I cases. However, it did not reduce the incidence of PCR. Incomplete capsulotomy during FLACS could happen in white cataracts. Using FLACS on white cataracts enabled more precise capsulotomies and better-centered IOLs.
