Abstract :

Statement of the Problem: Ophthalmic viscosurgical devices (OVDs) are viscoelastic solutions used in cataract surgery to create and maintain space in the anterior chamber of the eye during phacoemulsification and implantation of the intraocular lens (IOL). They can be classified into two general categories: cohesive and dispersive. Cohesive OVDs maintain the anterior chamber during the capsulorhexis and IOL implantation and dispersive OVDs protect corneal endothelium during the phacoemulsification. In general, it is necessary to use a dye prior to filling the anterior chamber with OVDs. The most used dye in cataract surgery is the Trypan Blue. Because they are separate substances, it is mandatory to perform two different surgical steps during the phacoemulsification. Combined OVDs are a recent innovation and they allow the execution of two surgical steps simultaneously. The purpose of this study is to evaluate the use of a new combined viscoelastic agent in patients undergoing phacoemulsification. Methodology & Theoretical Orientation: A longitudinal and prospective study of 20 eyes of consecutive patients with cataract was conducted at the Hilton Rocha Foundation, Brazil. All patients underwent a complete ophthalmologic examination before the phacoemulsification. During the perioperative period, a combined solution containing the viscosurgical HPMC 2% with 0.0012% trypan blue was used to fill the anterior chamber and stain the anterior lens capsule simultaneously. The efficacy of capsule staining was analyzed. Findings: Capsulorhexis was performed in all eyes without any difficulty. Filling of the anterior chamber and visualization of the anterior lens capsule were possible because of the HPMC and trypan blue, respectively. In the postoperative period there were no cases of toxicity or persistent corneal edema. Conclusion & Significance: The combined solution containing the viscosurgical HPMC 2% with 0.0012% trypan blue has the ability to fill spaces and blush the capsule simultaneously, resulting in greater safety, greater speed, simplicity and convenience in cataract surgery.
