Opacification of a hydrophilic acrylic intraocular lens with exacerbation of Behc¸et’s uveitis Chan Y. Kim, MD, Shin J. Kang, MD, Sung J. Lee, MD, Sung H. Park, MD, Hyoung J. Koh, MD Behc¸et’s disease is 1 of the most common causes of uveitis in the Eastern world. Its common ocular complications are uveitis, cataract, and obliteration of retinal vessels. Phacoemulsification with intraocular lens (IOL) implantation in patients with Behc¸et’s disease is known to be a safe procedure. We managed a patient with Behc¸et’s disease who had aggravated uveitis and opacification of a hydrophilic acrylic IOL (ACRL-C160, Ophthalmed) 4 months after cataract surgery. Recalcitrant uveitis despite maximum tolerable medication and IOL opacification with vitreous opacity necessitated an IOL exchange and trans pars plana vitrectomy. After the procedure, the eye became quiescent. However, the visual acuity was 20/200 because of the obliteration of retinal vessels.

he ocular complications in Behc¸et’s disease consist of uveitis, cataract, and obliteration of retinal vessels. Because uveitis and steroid medication increase the incidence of cataract in Behc¸et’s disease, cataract is 1 of the most common complications that occurs in ocular Behc¸et’s disease.1 Phacoemulsification with intraocular lens (IOL) implantation is reported to be a safe procedure in patients with Behc¸et’s disease, although there could be an ocular inflammatory attack after the cataract surgery.2 Recently, foldable IOLs have been reported to be safe in uveitis patients.3 However, we report a patient with Behc¸et’s disease who had aggravated uveitis and opacification of an implanted hydrophilic acrylic IOL.

Ophthalmed) in May 2000. On examination, the visual acuity in the left eye was 5/200. Although the cornea was clear and the anterior chamber quiescent, the vitreous showed many cells behind a uniformly opacified IOL (Figure 1). Extensive vitreous opacity as well as opacification of the IOL hindered visualization of the fundus. Oral colchicine and steroid were prescribed; however, the vitreous reaction did not improve after 5 months of the maximum tolerable medication. A reaction began to occur in the anterior chamber. Because the patient wanted to stop the oral medication, IOL exchange and trans pars plana vitrectomy were planned.

Case Report A 62-year-old woman was referred because of uncontrolled inflammation after cataract surgery in September 2000. Behc¸et’s disease had been diagnosed in March 2000. The patient had uneventful cataract surgery in the left eye with implantation of a hydrophilic acrylic IOL (ACRL-C160, Accepted for publication March 12, 2002. Reprint requests to Hyoung J.

An infusion cannula was introduced into the inferotemporal sclera 3.5 mm from the limbus. After a corneoscleral incision was made, sodium hyaluronate (Healon威) was injected into the anterior chamber. A Vannas scissor was introduced into the anterior chamber, and the IOL was divided and removed. As the irrigating solution was introduced into the vitreous cavity, the vitreous opacity was removed. The vitreous opacity was dense, and there was a posterior vitreous detachment. After the vitreous opacity was removed, the inferior temporal retinal vessels were found to be occluded. A single-piece heparin-surface-modified poly(methyl methacrylate) (PMMA) IOL (CeeOn威, Pharmacia & Upjohn) was fixated in the ciliary sulcus. One week after surgery, the eye was quiescent. At 3 months, the visual acuity was 20/200. The explanted IOL, including the haptics, was diffusely opacified (Figure 2). Scanning electron microscopy of the cut section of the optic showed granular deposits in a region about 5.0 ␮m beneath the anterior and posterior optic surfaces (Figure 3,A). Energy dispersive x-ray analysis was performed on the deposits in the same section and showed that calcium and phosphate peaks were present (Figure 3,B). However, there were no calcium or phosphate peaks in the surface and central area of the cut section (not shown).

There are several reports of opacification of the Hydroview威 model H60M IOL (Bausch & Lomb)4 – 6 and the foldable hydrophilic acrylic lens SC60BOUV (MDR Inc.).7,8 We report opacification in a different type of hydrophilic acrylic IOL.

x-ray analysis suggest that the IOL opacification in our case was the result of granular deposits composed at least in part of calcium and phosphate within the IOL optic, similar to the opacification in the SC60BOUV IOL.8 It is not clear whether intraocular inflammation causes opacification of the hydrophilic acrylic IOL or the hydrophilic acrylic IOL causes an attack of intraocular inflammation in patients with Behc¸et’s disease. In our patient, the posterior uveitis was not relieved by colchicine and steroid medication; however, the eye became quiescent after an IOL exchange. Therefore, we think the responses may be associated with use of the hydrophilic acrylic IOL in Behc¸et’s disease. We do not know why the vitreous opacity with posterior reaction was so severe while the anterior segment was relatively quiescent. Behc¸et’s disease was diagnosed in our patient 2 months before cataract surgery. In this relatively short time, the retinal vessel occlusion is an unusual finding in Behc¸et’s disease. We think the vitreous reaction with resultant vessel occlusion of the inferior temporal retinal vessel occurred after cataract surgery. Although this case cannot be applied to all Behc¸et’s disease patients or all hydrophilic acrylic IOLs, we recommend caution in the use of this hydrophilic acrylic IOL in patients with Behc¸et’s disease. Patients with Behc¸et’s disease who have this IOL should be followed carefully.
