Silicone oil is the one of the artificial materials used in vitreoretinal surgery for retinal detachment treatment. Since the silicone oil is sometimes applied along with intraocular lens (IOL) implantation the direct influence of silicone oil on the artificial implant should be taken into account. Presented study was performed in order to determine the time-dependent impact of silicone oil on hydrogel based ophthalmic materials. Two kinds of IOLs based on hydroxyethyl 2-methacrylate (HEMA) hydrogel material were immersed in silicone oil based on linear poly(dimethylsiloxane) (PDMS)...

Endophthalmitis following intraocular surgery can be devastating. This case report demonstrates successful management of late-onset Streptococcus mitis endophthalmitis treated by vitrectomy, panretinal photocoagulation (PRP) and silicone oil tamponade. A 75-year-old man presented with painful vision loss in his right eye. The patient had uneventful phacoemulsification and intraocular lens implantation in the right eye at an outside clinic 6 weeks prior. Examination disclosed hypopyon and vitritis, as well as discrete inflammatory collections in the vitreous...

PURPOSE: To assess the decentration and angle of tilt of the intraocular lens (IOL) according to the intravitreal tamponade types used in combined phacoemulsification and vitreoretinal surgery. METHODS: This prospective and randomized clinical study involved 73 eyes of 69 patients who underwent combined vitreoretinal surgery. Eyes with intravitreal tamponades formed the study group and eyes without intravitreal tamponades formed the control group. The study group was further divided into silicone oil and gas tamponade subgroups...

We describe a case of femtosecond laser-assisted cataract surgery (FLACS) in an eye with multiple comorbidities, including retinal detachment surgery, high myopia, posterior chamber phakic intraocular lens (PC pIOL) and residual, emulsified, silicone oil located in the anterior chamber. FLACS was affected by the optical blockage, but the incomplete capsular tear was recoverable. The case suggests that silicone oil bubbles concentrated at the dome of the posterior corneal surface, along with the PC pIOL optic edges and scars after corneal astigmatic relaxing incisions can lead to incomplete anterior capsulotomy...

Rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD) is a special type of complex retinal detachment, and usually has a poor prognosis. This study aimed to assess the anatomical outcomes of 23-gauge pars plana vitrectomy (23G PPV) combined with phacoemulsification (phaco) and capsulotomy without intraocular lens (IOL) implantation in patients with RRDCD.Seventy-six consecutive patients with RRDCD, who underwent retinal repair surgery from January 2010 to December 2014, were retrospectively analyzed...

PURPOSE: The management of chronic ocular hypotony and complicated proliferative vitreoretinopathy-related retinal detachment represents a challenge. Being non-absorbable and non-biodegradable, a silicone oil implant is expected to restore the volume and the intraocular pressure of the globe, as well as to approximate the detached retina. Further advantages could be a long-term tamponade potential, absence of toxicity, and prevention of silicone oil emulsification or anterior chamber oil-prolapse...

Deposition of dystrophic calcifications on the posterior surface of silicone intraocular lenses (IOLs) has been reported in patients with asteroid hyalosis. Accumulation of silicone oil droplets on the posterior surface of silicone IOLs in silicone-filled eyes has also been reported. Recently, a novel technique to manually remove dystrophic calcifications using a nickel titanium loop (Finesse Flex Loop; Alcon, Fort Worth, TX) was described, obviating the need for IOL exchange. Here, the authors report their outcomes with this technique in five eyes with IOL dystrophic calcifications as well as one eye with IOL silicone oil droplet accumulation...

Migration of intraocular silicone oil, used in the treatment of complicated retinal detachment, has been rarely described, but when it happens it can arise with a differential diagnosis with scleral buckling extrusion, tumor, dermoid, ocular cysticercosis, and abscess. The presence of silicone oil in the eye gives very ugly echographic pictures, but these kinds of pictures can be very useful in making a differential diagnosis in the above-mentioned cases. A 39-year-old white female complained of the presence of conjunctival hyperemia and tearing in the right eye (RE); her visual acuity was hand motion, and the intraocular pressure was 14 mmHg...

BACKGROUND: Silicone oil (SO) is used as an intravitreal tamponade agent in vitreoretinal surgery for rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy or with large, multiple retinal tears. Usually, SO is left in the eye for at least 3 months. Although its use can lead to well-known complications, intraocular SO is generally well tolerated. Some studies have reported unexpected central vision loss after SO use or removal. OBJECTIVE: To investigate and analyze the reason for visual loss after the use or removal of intraocular SO in patients who underwent vitrectomy surgeries for RRD...

Posterior capsular opacification (PCO) is common after cataract surgery. Recurrence is very rare after a successful Yttrium aluminium-garnet (YAG) capsulotomy in adults. We report a case of visual axis re-opacification after a successful YAG capsulotomy for PCO in an adult. A 60-year male underwent phacoemulsification with +20.0 D acrylic hydrophobic intraocular lens implantation and silicon oil removal (SOR) five months after a successful retinal detachment repair. He underwent a capsulotomy after two months of surgery; however, the visual axis re-opacified after three more months...

We present a case of bilateral choroidal and exudative retinal detachment with hypotony in a patient with septicaemia. Our patient after initial hospitalisation was treated by the local ophthalmologist as a case of sterile pan uveitis with systemic and topical steroids that did not have any effect. Our patient responded well to timely surgical intervention of choroidal drainage and vitrectomy with silicone oil tamponade followed by steroids and antibiotics. Cataract progression in both eyes occurred due to hypotony, inflammation, use of steroids and the vitreous surgery...

An 18-year-old boy with an obsessive-compulsive disorder of eye rubbing presented with forme fruste keratoconus (KC) and posterior subcapsular cataracts. After evaluation, he underwent phacoemulsification in his left eye with intraocular lens implantation. The aggressive eye rubbing, however, aggravated the rapid progression to established KC, and further acute corneal hydrops within 3 months. Within the next 3 months, the eye rubbing precipitated rhegmatogenous retinal detachments (RDs) in both eyes. Furthermore, after undergoing a combined cataract and RD surgery with belt buckling and silicone oil endotamponade in his right eye, the repeated eye rubbing caused extrusion of the implanted silicone oil into the subconjunctival space and within the corneal stroma...

Recognizing imaging characteristics after ophthalmic surgery is necessary for radiologists to prevent misdiagnosis. We review typical appearances of intraorbital implanted devices and materials on CT and MRI with demonstration of the common surgical procedures. EX-PRESS glaucoma filtration devices appear as punctate areas of metal attenuation on CT and are typically placed at the corneoscleral junction. The imaging manifestations after cataract extraction are absence of the native lens of ovoid mass and the intraocular lens with high attenuation on CT and low signal intensity on MRI...

BACKGROUND: Refraction change of silicone oil (SO) tamponade in phakic and aphakic eye has been studied thoroughly; however, it is rarely studied in pseudophakic eye. In this paper we aimed to deduce a theoretical formula predicting refractive shift of silicone oil tamponade in pseudophakic eye and compared it with clinical findings. METHOD: A theoretical formula was deduced through strict geometric optical principles under the Helmholtz Schematic eye model. Pre/postoperative refractive status of patients who previously underwent phacoemulsification, intraocular lens (IOL) implant, vitrectomy, SO tamponade and required SO extraction was studied...
