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.

Purpose To present an alternative cataract surgical technique in patients with cataract and intravitreal hemorrhage. Methods Twelve cases with poor fundus reflex caused by severe vitreus hemorrhage were included in the study. All patients underwent combined phaco surgery and 23-gauge vitrectomy. Chandelier retroillumination was inserted into the infusion trochar during the cataract operations and was used with low power (50-75%) in necessary steps. Results We did not experience phaco complications or complications due to technique during surgery. Retroillumination assistance was especially useful during final stages of cataract surgery, particularly irrigation-aspiration of cortical material. Conclusion Retroillumination in absence of red fundus reflex may be helpful and can be practiced more often in cataract surgery combined with vitrectomy.

“…In addition, femtosecond laser facilitates anterior capsulorhexis in cases with no fundal red reflex (vitreous haemorrhage) or in eyes with narrow anterior chambers, preventing additional intraoperative complications. Previously, in cases without a red reflex, staining with trypan blue and endo-illumination of the vitreous chamber [30] or 23-gauge illuminated infusion chandelier [31,32,33] were used, practices that we consider obsolete now femtosecond laser is available. Femtosecond laser does require additional specific conditions: an acceptable palpebral fissure for appropriate placement of the cone [34] and good pharmacological mydriasis to perform a capsulorhexis of the desired size.…”

Background: The aim of this study was to assess the safety and surgical results of femtosecond laser-assisted phacovitrectomy. Methods: A retrospective analysis of the medical records of patients over 50 years of age with vitreoretinal pathology, who had undergone pars plana vitrectomy using 23-gauge instruments and femtosecond laser-assisted cataract surgery and implantation of an intraocular lens, was performed at the Instituto de Microcirugía Ocular between June 2012 and September 2013. The diameter of the anterior capsulorhexis was set at 4.8 mm in cases where a gas tamponade was used and at 5 mm in all other cases. During the pars plana vitrectomy, posterior capsulotomy was performed on all eyes. An assessment was carried out of preoperative characteristics, surgical indications, postoperative results and complications. Only patients with a minimum of 3 months of follow-up were included. Results: A total of 21 eyes in 21 patients (71.4% women) were treated. Mean age (±SD) was 65.8 ± 6.4 years (range 53-76). The most common indication for surgery was epiretinal membrane (61.9%), followed by vitreous haemorrhage (23.8%) and macular hole (14.3%). The mean preoperative best corrected visual acuity (BCVA) was 0.81 ± 1.01 logMAR and the mean postoperative BCVA was 0.12 ± 0.19 logMAR (p = 0.003). 85.7% of patients improved their visual acuity. The remaining patients maintained their visual acuity. The only intraoperative complication related to femtosecond laser was 1 case of suction loss (4.8%). A patient with rhegmatogenous retinal detachment discovered during surgery required an additional circular scleral procedure and developed synechiaes in the early postoperative period (<1 month). There were no cases of subluxation of the intraocular lens. Mean follow-up was 6 months (range 3-14). Conclusions: The application of femtosecond laser in phacovitrectomy is a safe and effective technique that presents advantages compared to conventional techniques in cases of macular pathology and/or vitreous haemorrhage.
