Retinal protection using a viscoadaptive viscoelastic agent during removal of a luxated crystalline lens by intravitreal phacoemulsification

Intravitreal Phacoemulsification with Pars Plana Vitrectomy for Management of Posteriorly Dislocated Nucleus or Lens Fragments

“…Our results show more patients with visual acuity of 0.5 (equivalent to 6/12 Snellen notation) or better than what had been reported by Margherio et al (17), who agent as a safeguard has been reported in a case report. It allowed for protection of the posterior pole without rolling down the lens fragments towards the periphery of the retina, which is a clear advantage over perfluorocarbon use, but the results need further confirmation (14).…”

Use of viscoelastic substance in ophthalmic surgery — focus on sodium hyaluronate

“…A similar technique was also reported for prevention of the contact between indocyanine green and the retinal pigment epithelium in a macular hole (Saito and Iida 2006). Regarding mechanical protection of the retina, Hanemoto et al (2004) reported that intravitreously injected Healon ® 5, which covered the posterior pole, prevented retinal damage during removal of a luxated crystalline lens by intravitreal phacoemulsification.…”

Experimental measure of retinal impact force resulting from intraocular foreign body dropped onto retina through media of differing viscosity

“…This is encountered commonly while attempting to extract an irregularly shaped piece of metal through a sclerotomy, whether performing magnetic or forceps extraction. Some authors have recommended using perfluorocarbon liquids (PCLs), silicone oil, or viscoelastics to protect the retina in similar surgical scenarios 3–9…”

“…Some authors have recommended using perfluorocarbon liquids (PCLs), silicone oil, or viscoelastics to protect the retina in similar surgical scenarios. [3][4][5][6][7][8][9] PCLs have a set of physical properties like high specific gravity, immiscibility in water, low viscosity, transparency and a refractive index close to that of water; that makes them useful intraoperative adjuncts in the management of complicated vitreoretinal conditions. 10 During vitrectomy for IOFB extraction, less dense objects such as intraocular and crystalline lenses, rubber and plastics float on the surface of the PCL, assisting in their safe removal.…”
