Purpose: In this paper, we present a case of acute clouding of a trifocal intraocular lens (IOL) that resolved spontaneously by the day after surgery.

Observations: A 68-year-old woman with a nuclear cataract in the right eye was scheduled for cataract surgery with +21.00 diopter trifocal IOL (AT LISA tri 839MP, Carl Zeiss Meditec AG, Germany) implantation. Phacoemulsification was uneventful until the implantation of the IOL. Although the IOL was initially transparent, we observed acute clouding of the IOL optic immediately upon implantation into the eye, and the IOL remained cloudy at the end of the surgery. On the day after surgery, we observed that the clouding was completely resolved.

Conclusions And Importance: We think that the sudden temperature change of the IOL upon implantation into the anterior chamber may have caused acute clouding. If a similar situation is encountered, clinicians should avoid explantation or replacement of the Zeiss AT LISA trifocal IOL, as the clouding resolves spontaneously.

This case report details a 12-year-old male diagnosed with Hurler syndrome, a rare autosomal recessive disorder caused by a deficiency in the enzyme alpha-L-iduronidase. The patient exhibited typical symptoms, including developmental delays, ocular clouding, and distinctive skeletal deformities, along with mild cognitive abnormalities. Despite the presence of traditional clinical signs and elevated urine heparin and dermatan sulfate levels confirming the diagnosis, access to advanced treatments such as enzyme replacement therapy was severely limited due to socioeconomic constraints and a lack of diagnostic facilities in the region.

Rationale: Corneal opacity can be caused by various disease. Generally, the opacity gradually increases as the disease progresses. Sudden corneal opacity is mainly caused by corneal trauma, toxic drugs entering the cornea, or acute edema of the keratoconus.
