Staining the Anterior Capsule with Indocyanine Green or Trypan Blue for Capsulorhexis in Eyes with White Cataract

Aim: To assess the efficacy and safety of indocyanine green (ICG) 0.5% and trypan blue 0.1% for anterior capsule staining in cases of white cataract. Methods: This prospective study comprised 55 eyes of 55 patients with white cataract that had phacoemulsification with foldable intraocular lens implantation. ICG in 30 eyes and trypan blue in 25 eyes were used under air to stain the anterior lens capsule. The staining patterns and the ease of creating a continuous curvilinear capsulorhexis (CCC) were assessed; the intraoperative and postoperative complications were noted. The mean follow-up was 17.68±1.65 months. Result: Either ICG or trypan blue stained the anterior capsule uniformly. However, the staining provided by trypan blue was slightly superior. A CCC was successfully achieved in 25 eyes (100%) with trypan blue, and 29 eyes (96.7%) with ICG, respectively. There was no significant postoperative reaction in any eye. Conclusion: The use of vital dyes such as ICG and trypan blue guarantees a complete CCC and makes it possible to deliver the benefits of phacoemulsification in the patients with white cataract.     

Trypan-blue- and endoillumination-assisted phacoemulsification in eyes with vitreous hemorrhage during combined cataract and vitreous surgery

PURPOSE: To study the safety and usefulness of trypan blue application and conventional endoillumination for enhancing visualization during phacoemulsification and foldable intraocular lens implantation in cases of cataract with vitreous hemorrhage. METHODS: Ten eyes of 10 patients with cataract and coexisting vitreous hemorrhage underwent combined trypan-blue- and endoillumination-assisted phacoemulsification and foldable intraocular lens implantation with vitrectomy. In a two-step surgery, after staining the anterior capsule with trypan blue, continuous circular capsulorhexis was performed; then, phacoemulsification was performed using conventional endoillumination. Specular microscopy was performed before and 3 months after surgery on eyes that underwent trypan-blue- and endoillumination-assisted phacoemulsification and on control eyes that underwent standard phacoemulsification to evaluate the toxic effect of trypan blue on corneal endothelial cells. RESULTS: Trypan blue application improved visualization of the anterior capsule, and a complete capsulorhexis could be performed in all eyes. In all 10 eyes, endoillumination was required to visualize the lens structure, and phacoemulsification could be accomplished. Specular microscopy revealed that there was no significant difference in the level of corneal endothelial cell loss between the trypan-blue- and endoillumination-assisted phacoemulsification group and the control group. CONCLUSION: The described double visualization technique may assist phacoemulsification in selected cases of cataract with vitreous hemorrhage.     

老年性白内障超乳术中晶状体囊相关风险研究

目的 评估不同程度老年性白内障超声乳化手术中晶状体囊相关的手术风险。方法 回顾性分析老年性白内障的超声乳化手术432例（566眼）。根据白内障成熟程度分为研究组（成熟期和过熟期白内障）和对照组（未熟期白内障）,记录术中发生的相关并发症,以Fisher精确概率法将两组间的数据进行对比分析。结果 在研究组232眼中,撕囊失败12眼（5．2％）,后囊破裂6眼（2．6％）,其中4眼（1．7％）人工晶状体固定在睫状沟;在对照组334眼中,所有病例均成功完成了撕囊,2眼后囊破裂（0．6％）,所有病例的人工晶状体均成功植入囊袋。结论 成熟期和过熟期老年性白内障超声乳化手术晶状体囊相关并发症发生率较未熟期高（X^2=18．54,P〈0．01）,尽管应用囊染色剂可以方便撕囊操作,但是撕囊仍是成熟期和过熟期白内障的超声乳化手术中最困难的步骤。     

Trypan-blue-assisted anterior continuous curvilinear capsulorhexis in a case of ocular pemphigoid

PURPOSE: To report on trypan-blue-assisted anterior continuous curvilinear capsulorhexis (ACCC) in a case of ocular pemphigoid. METHODS: Interventional case report. RESULTS: Due to the reduced visibility especially in the corneal periphery caused by the ocular pemphigoid, trypan blue 0,06% (Acri.Blue) was used to stain the anterior capsule of the lens. Then anterior continuous curvilinear capsulorhexis was performed. Due to the blue staining, the visualization of the margin of the rhexis was always good and phacoemulsification procedure was successfully performed afterwards. During the follow-up period of 12-months-postsurgically, no exacerbation of the ocular pemphigoid occurred. CONCLUSIONS: The use of trypan blue staining of the anterior capsule enabled the surgeon to perform a safe anterior continuous curvilinear capsulorhexis and a subsequent phacoemulsification in ocular pemphigoid. No progression of the ocular pemphigoid was seen within the 12-months-post-surgery period.     

Anterior capsule staining for capsulorhexis in cases of white cataract: comparative clinical study

PURPOSE: To compare the safety and efficacy of trypan blue 0.1%, gentian violet 0.001%, indocyanine green 0.5% (ICG), fluorescein 2%, and the patient's autologous blood for anterior capsule staining in cases of white cataract. SETTING: Rajendra Prasad Center for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India. METHODS: Fifty eyes of 50 patients with age-related white cataract had anterior capsule staining with trypan blue, ICG, or gentian violet under an air bubble or subcapsularly with fluorescein or autologous blood followed by phacoemulsification with foldable intraocular lens implantation. Each stain was used in 10 eyes. The ease of creating a continuous curvilinear capsulorhexis (CCC) and the complications during the surgery were noted. Postoperative examinations at 6 hours, 1 day, 1 week, and 1 month included slitlamp microscopy, uncorrected visual acuity, and best corrected visual acuity (BCVA). The staining patterns on the anterior capsule, side port, corneal tunnel, and anterior cortex were assessed intraoperatively and within 6 hours and at 1 day. The intraocular pressure (IOP) was assessed at 1 day; pachymetry, at 1 day and 1 month; and the endothelial cell count, at 1 month. RESULTS: The surgeon had best visualization during the anterior capsulorhexis with trypan blue, ICG, and gentian violet, and a complete CCC was achieved in all eyes in the 3 groups. Two eyes each in the fluorescein and autologous blood groups had extension of the CCC so that the capsulorhexis was complete but not curvilinear. Anterior capsule fibrosis was detected with trypan blue (1 eye) and ICG (2 eyes). The anterior vitreous was stained with fluorescein in 2 eyes. All eyes achieved a BCVA of 20/30 or better from 1 week postoperatively to the last follow-up. The side port and corneal tunnel were stained most intensely with gentian violet followed by trypan blue and ICG and less intensely with fluorescein and autologous blood. The IOP, pachymetry, and endothelial cell loss were comparable between the stains. CONCLUSION: Although trypan blue, ICG, gentian violet, fluorescein, and autologous blood were safely used to stain the anterior capsule for phacoemulsification in eyes with white cataract, trypan blue, ICG, and gentian violet were more effective in staining the capsule.     

Phacoemulsification in anterior megalophthalmos

This case outlines the phacoemulsification technique used to overcome the challenge of the hyperdeep anterior chamber, weak zonules, abnormal anterior capsule, and large capsular bag. Key steps included trypan blue staining of the anterior capsule, a large capsulorhexis, prolapse of the nucleus into the anterior chamber with phacoemulsification anterior to the capsulorhexis, and a posterior chamber-placed iris-clip intraocular lens. Successful visual rehabilitation is achievable in these anatomically challenging eyes.
