Ocular trauma is among the common causes of dislocation of lens. An eleven year old male child having history of getting operated on his right eye for congenital cataract with implantation of intraocular lens as well as for subsequent retinal detachment in later phase of life, presented with complains of decreasing vision and pain in right eye after having encountered a blunt trauma. Alongside an anteriorly dislocated IOL and herniated silicone oil bolus in the anterior chamber gave the appearance of a polypseudophakia. Complete clinical examination along with a detailed history is the way for avoiding gross clinical misdiagnosis and thus employing appropriate management.

An 11-year-old male child presented with complaints of ocular pain and gradual diminution of vision in the right eye (RE) for 2 months. His father revealed a history of blunt trauma by sibling's fist while playing 2 months back.
Best-corrected visual acuity (BCVA) in RE was 20/400. At first glance, on slit-lamp examination, anterior chamber (AC) in RE appeared accommodating two intra-ocular lens (IOL) optics, one over another resembling dislocated piggyback IOL [Figure 1]. After retracting the upper lid, emulsified silicone-oil droplets were found deposited superiorly in AC. This led to the diagnosis of a herniated silicone-oil bolus lying in front of IOL optic. IOL might have dislocated into AC due to trauma along with herniation of oil from the posterior segment [Figure 2]. B-scan confirmed silicone-oil filled vitreous cavity. IOP was 34 mmHg on applanation tonometry. Fundoscopy revealed silicone-oil-filled vitreous cavity, well-attached retina, and CDR of 0.7:1 indicating glaucomatous optic disc damage. Left eye examination showed BCVA 20/20, well-placed IOL in the capsular bag, and unremarkable posterior segment.

This child was started on antiglaucoma medication to reduce IOP and advised for silicone oil removal and IOL explantation with scleral-fixated IOL implantation.
The patient's old record revealed congenital cataracts in both eyes which were extracted followed by IOL implantation. The patient later had rhegmatogenous retinal detachment in RE for which vitreoretinal surgery was done and silicone oil was injected 1 year back elsewhere. He was advised for silicone oil removal to which he did not comply.
This is a case of “reverse-hypopyon” or “hyperleon.” It can develop when silicone oil used during vitreoretinal surgery if not removed on time gets emulsified and enters into AC. It blocks the trabecular meshwork leading to a rise in IOP. Long-standing raised IOP damaged optic nerve. Silicone oil being lighter than aqueous humor appears like a layered hypopyon in the superior quadrant of AC., The aim of silicone oil use as a vitreous substitute is to provide tamponade to a detached retina.
A major drawback of silicone oil is its tendency to emulsify. Emulsification means formation of oil droplets at the interface between oil-bubble and intraocular fluid. It leads to dispersion of these droplets into aqueous and vitreous humor with a consequently higher risk of proliferative vitreoretinopathy, retinal re-detachment, inflammation, secondary glaucoma, and keratopathy.
