“…Several reports described the opacification occurred after intravitreal gas injection during pars plana vitrectomy (PPV), the surgical procedure performed for treating diseases of the posterior segment of the eye [ 6 , 23 , 32 , 36 , 68 , 69 , 70 , 71 , 72 ]. The typical appearance of the opacification in most cases was similar to that occurring after DSAEK/DMEK [ 6 , 17 , 23 , 32 , 36 , 62 , 68 , 69 , 70 , 71 , 72 ]. Because the opacification appears mainly on the anterior surface of the IOL, although gas is injected into the vitreous, it is presumed that gas is likely to migrate into the anterior chamber through damaged zonular fibers [ 70 ].…”

“…Opacification of hydrophilic acrylic IOLs following intraocular gas injection has been described not only after intracameral injection of air or gas. Several reports described the opacification occurred after intravitreal gas injection during pars plana vitrectomy (PPV), the surgical procedure performed for treating diseases of the posterior segment of the eye [6,23,32,36,[68][69][70][71][72].

Physicochemical Analysis of Sediments Formed on the Surface of Hydrophilic Intraocular Lens after Descemet’s Stripping Endothelial Keratoplasty

An intraocular lens (IOL) is a synthetic, artificial lens placed inside the eye that replaces a natural lens that is surgically removed, usually as part of cataract surgery. The opacification of the artificial lens can be related to the formation of the sediments on its surface and could seriously impair vision. The physicochemical analysis was performed on an explanted hydrophilic IOL and compared to the unused one, considered as a reference IOL. The studies were carried out using surface sensitive techniques, which can contribute to a better understanding of the sedimentation process on hydrophilic IOLs’ surfaces. The microscopic studies allowed us to determine the morphology of sediments observed on explanted IOL. The photoelectron spectroscopy measurements revealed the presence of organic and inorganic compounds at the lens surface. Mass spectroscopy measurements confirmed the chemical composition of deposits and allowed for chemical imaging of the IOL surface. Applied techniques allowed to obtain a new set of information approximating the origin of the sediments’ formation on the surface of the hydrophilic IOLs after Descemet’s stripping endothelial keratoplasty.

Intraocular lens opacification after Descemet's stripping automated endothelial keratoplasty

Compared with conventional penetrating keratoplasty, Descemet's stripping automated endothelial keratoplasty (DSAEK) more effectively maintain global integrity and rapid vision rehabilitation with less ocular surface disorders in patients with endothelial dysfunction. Here, we report a case of a 76-year-old woman who experienced opacification of a hydrophilic intraocular lens (IOL) approximately 10 months after DSAEK. The patient with no history of systemic disease developed pseudophakic bullous keratopathy in the right eye 2 years after undergoing cataract surgery. The best-corrected visual acuity (BCVA) of the right eye was Snellen 0.01 when presented to our hospital. DSAEK was arranged and performed smoothly. However, the graft detached over the upper part of the cornea on postoperative day 1. Thus, rebubbling was performed immediately. After the procedure, the graft was well attached, and the cornea became clear gradually. The BCVA returned to Snellen 0.6. However, progressive opacification over the anterior surface of the IOL was observed 10 months postoperatively. Vision deteriorated to 0.5 with various refractive errors during 2-year follow-up. IOL exchange may be considered if the vision is getting worse. IOL opacification may result from a direct contact between the IOL surface and exogenous air, particularly in a hydrophilic IOL, and can be a rare but significant complication after DSAEK. Clinicians planning to perform DSAEK should consider the composition of the IOL, the amount of intracameral air, duration of air filling, and high intraocular pressure.
